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.

Dog Point Set Screw: The Most Commonly Used Set Screw

A socket set screw is a specific type of threaded fastener, which usually does not feature a head. Unlike other kind of commonly used rivets, this metal piece is basically an adjustment device generally used to develop axial chunk. Such kind of screw comes handy and is used for multiple uses. Plus, it is also available in various types, the most common type, being the dog point set screw.

Such type of fastener is used to clutch body parts like collar, gear, sleeve, coupling etc. into an axle, so as to prevent relative oscillation. The socket feature helps such kind of screw to effectively rotate in a desired direction. The sockets are available in various types, including fluted socket, square head, screwdriver slot, hexagon socket and much more in the list.

You should always consider the point of your fastener before purchasing it. You should know which model is suitable for your job. The point of a rivet is the area, which rotates against the shaft during penetration. The point selection is usually done by determining the nature of the functionality. The point is available in various types, which are as follows:

Dog Point Set Screw:

It is the most common type, mostly used for fixing into any permanent location of one surface to the other. It features a broad flattened end, followed by its angular threads ending before just above the tail. The fastener’s end is placed in the already drilled hole in shaft or on a flat surface. It is often replaced with the dowel pinions and always works well against the must rugged surface or hollow tubing.

Flat type:

Such kind of point is used on those surfaces, where parts are always replaced or re-set. IN this frequent application, such kind of point helps prevent damage or any kind of wear and tear.

Knurled Cup:

This type of point is used for permanent locations, including collars, gears, knobs, pulleys and shafts. This particular head is able to resist more amount of vibration.

Plain Cup:

This point is used for style set screw. It is usually used in permanent as well as fluctuating locations mainly on shaft, featuring hardness differential of 10-15 Rockwell C points and in those areas, where the cutting of the cap is acceptable.

You can select any of these above set screws, determining the nature and requirement of your job.

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.
