Button Head Hex Screw Black Zinc Plated Socket Head Screws Plastite

Button head hex screw is commonly used in machine parts, die fixturing, and clamping. The hex socket head enables driving where there is not sufficient space for wrenches or sockets and allows the screw head to sit flush with the surface. Ever Hardware provides custom-made fasteners and customizable packaging.

The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench, also known as an Allen wrench, Allen key, hex key or inbus as well as by a hex screwdriver (also known as a hex driver) or bit. Tamper-resistant versions with a pin in the recess are available.

Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated.

The PLASTITE screw is designed to facilitate thread-forming in less-compressible plastics while providing high resistance to strip-out and pull-out.
