1/4-20 hex washer head thread cutting screws, Type F, in 410 stainless steel to ASME B18.6.3. Machine-screw thread with a blunt, slotted cutting point that cuts its own mating thread in pre-drilled or cored holes in sheet metal, castings and plastics, giving a thread that takes a standard machine screw. The hex head has a built-in washer face that spreads the load and protects the surface, with a 3/8" external hex for a nut driver or socket. 410 stainless is hardened for cutting into harder materials and is magnetic. 3 lengths (5/8" to 1"). Sold in production-volume bulk packs.
