Product Description

The alloy steel socket cap screw has a black oxide finish and a button head with a pin-in-head hex drive, meets American Society of Mechanical Engineers ASME B18.3 and American Society for Testing and Materials ASTM F835 specifications, and is made in USA. Alloy steel is often used in applications where strength is the primary consideration. The black oxide finish offers mild corrosion resistance and lubricity. The button head is round with a low profile and short vertical sides, and is suitable for light duty applications. The pin-in-head hex drive has a hexagonal indentation with a center pin that resists tampering by requiring a special driver to tighten or loosen the screw.

Socket cap screws are threaded fasteners that have a cap head with an internal socket drive for installing in areas with limited side clearance. These screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles, which determine the type of tool required to install the screw.
