Product Description

The alloy steel socket cap screw has a plain finish and a button head with an internal hex drive, and meets American Society of Mechanical Engineers ASME B18.3 and American Society for Testing and Materials ASTM F835 specifications. Alloy steel is often used in applications where strength is the primary consideration. The button head is round with a low profile and short vertical sides, and is suitable for light duty applications. The internal hex drive, also known as a hex-socket drive, has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench.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.
