18-8 Stainless Steel Set Screw, Plain Finish, Hex Socket Drive, Cup Point, Meets ASME B18.3/ASTM F880, 1/2" Length, 1/4"-28 UNF Threads, Imported (Pack of 100)

The 18-8 stainless steel set screw with plain finish has a hex socket and cup point, and meets American Society of Mechanical Engineers ASME B18.3 and American Society for Testing and Materials ASTM F880 specifications. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The hex socket drive has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench. The cup point has an edge that grips the mating surface with enough power for use in permanent and semi-permanent applications.

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.
