The stainless steel socket cap screw has a plain finish and a flat head with an internal hex drive. Stainless steel resists corrosion and may be magnetic. The flat head is cone shaped for use in countersunk holes and has a flat top that fits flush with the mated surface. 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.General Product Information:Head Style: FlatDrive Style: Allen Hex KeyDrive Size: 5/16"Screw Size: 1/2-13Length: 1-1/2"Quantity of Fasteners in Package: 25Detailed Product Information:Head Diameter: 0.882"Head Height: 0.265"Countersink Angle : 82 DegreeThread Diameter: 0.500"Thread Per Inch (TPI): 13Thread Style: CoarseThread Coverage: Full ThreadThread Length: 1-1/2"
