Alloy Steel Set Screw, Black Oxide Finish, Hex Socket Drive, Cone Point, Meets ASME B18.3/ASTM F912, 3/8" Length, #4-40 UNC Threads, Imported (Pack of 100)

The alloy steel set screw with black oxide finish has a hex socket and cone point, and meets American Society of Mechanical Engineers ASME B18.3 and American Society for Testing and Materials ASTM F912 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 hex socket drive has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench. The cone point is conical with a sharp point for penetrating material and providing a strong, permanent hold.Set screws hold objects in place by use of pressure at the point, and are often used in semi-permanent applications and where fine adjustment is needed. Set screws are available with a variety of point styles, which determine how the screw interacts with the object it is placed against. These threaded fasteners typically do not have an external head.
