Salient Features of Hammer Drive Screws
U-drive self-tapping screws, which are also known as hammer drive screws, are unslotted fasteners featuring round-shaped head and numerous start threads along-with a huge corkscrew-shaped angle and an unthreaded pilot point.
This particular fastener is hard-as-nails and is far more rigid than the pairing part and is to be either screwed or hammered into any substrate, say castings, plastics or sheet metals for a fastener diurnal assembly. Besides, this kind of rivet also requires a miniature pre-drilled hole to render maximum adhesion.
This special type of screw is available in zinc or black oxide coated steel material and also in stainless steel in sizes ranging from #00 – #8 and lengths between 1/8 and ¾.
