Product Description

The alloy steel socket cap screw has a black oxide finish and a button head with an internal hex drive, has a nylon patch, and meets American Society of Mechanical Engineers ASME B18.3, American Society for Testing and Materials ASTM F835, and Industrial Fasteners Institute IFI 124 specifications. 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 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. The nylon patch on the threads locks the screw in place once installed and prevents loosening due to vibration.

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.
