Eye Lag Screws: Ideal for Fixing Both Metal as well as Wooden Objects

An eye lag screw is basically used to fasten the back surface of your pole with the end of a guy wire. It is also used to fasten your desired anchor point to the end of a bungee cord. At Mutual Screw and Supply, we never encourage you to use such kind of fastener to anchor your main zip line cable. Instead, we suggest you to use an eyebolt or cable sling.

Eye Lag Screw

Before buying an eye lag screw, you should always measure the length from the base of the eye till the point where the threads end. For instance you can go for a 4″ lag screw, which features a shank length of 4 inches with its eye portion extending past this, especially if you are looking for attaching any suspended ceiling hanger wire to the wood.

These kinds of screws resemble eyebolts, except for the feature that they screw into objects, instead of passing through them. We would never suggest you to use them to anchor your zip line, but they feature a bunch of other applications, such as making hammocks and stuff.

We offer an array of such types of fasteners for fastening both metals as well as wooden objects, including installing various industrial tools. While the self-tapping & sharp-point rivets are inserted without pre-drilling holes in the receiving surface, these fasteners are drilled with an eye lag jig pole, along-with a 6.4 mm hex driver and a variable speed drill having a minimum speed of 200 rpm.

The sharp point ends of such screws get easily inserted by using the Eye lag installation tool (ELAT). These usually work from the floor by using the I-Lag telescopic pole and are ideal for hanging plants from patio ceilings.

Some basic features of stainless steel eye lag screws:

Easy installation

Their sharp eye points get easily and quickly inserted into wood

Ideal for both interior as well as exterior applications

Safe working Load = 120 pounds

Ideal for fixing ceiling hanger wire to wooden joists

Feature Self tapping sharp point

Salient Features of Clutch Head Screws

If you happen to see some kind of odd bow-tie shaped screw slots on your door or window pane, you’ve probably discovered the clutch head screws.  Such fasteners were extensively used in the auto industry from the 1940s through the 1960s. In 1970s, few of these screws also paved their way into travel trailer manufacturing industries as well.

10X High security clutch screws

Clutch head screws are also known as One Way Screws and ‘Security Screws‘. These specially designed fasteners are used for lasting installations. These are easy to use and can be installed using a normal screwdriver. The head of such kind of fastener features a normal drive and slanted rear face, which prevents the screwdriver from applying torque when trying to loosen these fasteners.

Once implanted, these rivets require typical drilling application for removal from the holes. However, you can even fetch for a special kind of driver bit to undo them.

Steel Clutch Head screws

In order to unscrew these rivers, you’re required to use a screwdriver bit of the same shape and size. The clutch head one way screws can be unscrewed in the clockwise direction by using a standard slotted screwdriver. This drive system was probably the worlds first security recess.

Unique Design

This unique feature enables such screws to be tamper-proof, thereby enhancing the security of your house and lessening the risk of robbery and making it impossible for the intruders to tamper the screws. Due to their unique design, there are even ideal for higher torque applications.

A Retrospect to the Standard Screw Sizes

The use of fasteners has grown extensively worldwide, increasing the need of coming up with standard screw sizes. Standardization prevents the use of improper screws, and ensures screws are compatible with the materials being used and are appropriate for the project at hand. Screw dimensions include the driver type — such as flat, Phillips or hex — length, shank diameter and threads per inch.

The demand for fasteners has extensively grown globally, especially in the world of online marketing. This growing demand has simultaneously increased the requirement for standard sizing of these hardware supplies.

By classification, the hassle of each time landing up with screws with different patterns and lengths can be greatly avoided. This even ensures that these rivets become comme il faut with the materials, being used in the construction or any build-up project. The various dimensions of these fasteners demand ofr use of various type of screwdrives, such as hex, Phillips, flat determining the shank diameter, length and threads per inch.

Screw’s numbering system

when standardization was done, the screws were put into 2 distinct numbering systems; the metric and U.S numbering systems. The metric measuring system lists out the diameter of these rivets in millimeters first and then secondly in thread pitch. The examples for this category include 6 mm x 1.0, 4 mm x 0.7, 5 mm x 0.8 etc. The U.S stadnard measurement system inlcudes screw with diameter sizes as 0, 1, 2 ,3, 4, 5, 6, 7, 8, 9, 10, 12, 14 and 16 and even in fractional sizes ranging from  1/4″ to 2″ in 1/16″. This is followed by threads and dash per inch falling between 6 and 80.

Diameter of screws

The first number metioned in the size charts for diameter must match the inner diamter of the washers ad nuts applied to them. The diameter of the rivet is measured at the shaft, just below the screw head. The diamter size ranging from 0 to 16 is declared by the American Society of Mechanical Engineers, thereby enabling the hardware sizing system to be extensively adopted worldwide. This kind of measurement made in standard U.S fractions was recently added and countries outside of America  are also seen following this standardization.

Length of screws

While the pan head screw’s length is measured from the flat end of its round head to its tip, the length of the flat head screws measure from the top of the head to the tip of the rivet.

The length is the third item typically listed in the size chart and is identified by an ‘x’ symbol. For instance, a #8-20 x 3/4″ screw features 20 threads per inch and a shaft measuring 3/4″ in length and a 5/8-24 x 1″ screw has a diameter of 5/8″, 24 threads per inch and has a 1″ shaft.

There are some fasteners, which are measured as per the threads per inch sizing, execpt for their length and diameter such as 5/16 x 1/2″ and #10 x 1″

Threading of screws

This kind of measurement is at number 2 in the chart of standard screw sizes. The hyphen refers to the number of threads of screw shaft per inch. For e.g. a 1/4-28 sized screw has diameter of 1/4″ along-with 28 threads per inch and a #6-32 screw has 32 threads per inch on its shaft.

Features and Types of Black Carriage Bolts

Black carriage bolts are mainly used in fixing two wooden pieces and these are also known as plow bolts. These types of fasteners feature a domed head followed by a square base right beneath the top. These square necks prevent the fastener from spinning when the nut is applied. These are also available with ribbed neck.

Black Carriage Bolts

These fasteners, along-with timber bolts feature no drive and machine threads, which are used for a nut. Instead they feature a rivet, flaunting a square shoulder beneath their domed top, which withstands the spinning when the nut is fastened.

What are Sheetrock Screws?

A Quick Review

Sheetrock screws, which are also known as drywall screws are extremely sturdy and long enough to be applied on drywall or sheet rock surface. These are made up of black phosphate and comprises of finished steel.

The unique cornet-shaped angle present beneath the head enhances the bearing area against the easily ruptured drywall surface.
These fasteners render better holding capacity as compared to nails and hence reduce the chance of popping out, thereby preventing any damage to the panel. These are used for fastening drywall to wooden or metal studs.

Ad Nauseam

Sheetrock® is the business name for USG Corporation’s drywall product, which is also known by several other names in different nations, such as Gibraltar board, plasterboard, gypsum board, wallboard, GIB wall, ceiling linings and rock lath.

It is manufactured in specific designs, so as to meet the construction standards put forward in building codes. The most important feature of this fastener is that it saves considerable amount of time, which is required to upright, the ceilings and interior walls in any form.

Although there are various procedures involved in the sheetrock screws installation, there are certain techniques applied, particularly in new constructions.


What’s in a name?
The name “drywall” suggests that walls made of certain materials are constructed without using water. A long-prevailing issue with plaster was that it took considerable time for drying, as it was installed wet, and the workers had to wait for this layer to dry-up before proceeding for the next one. The word “gypsum” is derived from the Latin term “gypsos,” which means “plaster.”

Specifications

These screws are designed in various sizes, including 48 inches, 96 inches and even 144 inches. These rivets are used determining the various requirements by different building codes and studs, made up of hollow steel sheets or wooden beams. These studs are used to support the interior walls and are positioned at about 16 inches gap. While the general ceiling height is 8 feet, the sheetrock screws’ dimensions alleviate them both vertically and horizontally, with every step featuring several proponents.

This 16-inch gap signifies the center of each stud. After all the fasteners have been inserted, the walls are then constructed using joint compound. This compound is spread over both the joints and screw holes between each joint.

Once the composite dries up, the walls are then sanded smooth and ready for whitewash.
The countersunk heads of the drywall screws are the most essential features. The entire fastener lies smooth with the surface of the sheet, thereby creating a great finish. The countersunk head helps in restricting the screw from damaging the paper surface, which is usually a common problem with all the nails.

Types & Uses

The sheetrock screws are usually of two types: Type ‘W’ and Type ‘S’. While the first one includes the wooden screws, featuring coarse and wide threads, the later one includes metal rivets, which are used along-with the steel framing members.

Another great feature of these fasteners is that they feature an edged and notched head, which can easily insert into the steel framing and their fine threads help them even penetrate into the steel surface.

Formed Wire Eye Bolts with Hex Nuts

Process

The drop forging is a type of metalwork process, which helps in gradually shaping a heated piece of metal, known as ingot. This technique involves creation of ingot, by giving repeated blows from a hammer or a die. This is done by raising and then dropping the hammer on the metal piece, thereby either flattening it or molding it to a desired shape.

Special shank, Thread Lengths and other sizes of Eye bolts

Determining the intricacy of the required design, the procedure sometimes involves numerous dies and other steps as well.

The drop forged eye bolts are usually produced with a close approximation of the finished metal piece. In some cases, some additional method, such as machining is involved, so as to obtain the required tolerance. It is a type of manufacturing process, which is used to create objects out of metal. Click here to know more.

Shoulder Pattern Type Drop Forged Eye Bolts

The drop forged eye bolts are used extensively in the automotive industry in producing various engine parts, gears and axles.

The dies used in this method are typically made up of high alloy steel known as tool steel. Such dies are designed specifically to become resistant to daily wear and tear. These are also capable of withstanding repetitive rapid heating and cooling cycles.

Forged Eye Bolts Recommended Load Limits

The dies used in this technique are made into two halves. While the upper half, known as hammer, is fastened to the raised block, that is dropped into the ingot; the lower half, known as anvil, is a rather stationary die used against the ingot, that is forged.

Another commonly used drop forging method is the open-die type. In this method, the dies do not completely encircles the work-piece. This kind of die is usually flat unlike contoured dies and cutting dies and are far more superior than the normal dies.

Open Die type Drop Forging method

This kind of open design accounts room for the expansion of the ingot, when it is hammered to the desired thickness.

The drop forged eye bolts are also prepared under various other techniques such as cogging and edging, impression-die forging and closed-die forging known as flash-less forging.

These rivets, which are available in steel and C-1023 type, are usually supplied standard fasteners featuring a hot galvanized finish.

Steel drop forged Eye Bolt

Before being exposed to galvanizing, they are threaded and enabled with hex nuts tapped unshapely, which assist in galvanizing thickness. Special shank and thread sizes for these rivets are also available in the market. As per your requirements, you can choose accordingly.

For these fasteners, loads are applied on a safety factor from 5 to 1. When tested, all such eye bolts are easily pulled at a uniform rate of speed in a direct tension. However, be warned that any kind of deviations, including shock loads, angular lifts, modifications of the basic forging etc. will result in dramatically reduced maximum loads.
