1/4-28 x 3/8 Half Dog Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel half dog point socket set screw with a nylon insert for prevailing torque. Use the half dog style where the receiving hole, slot, or groove is part of the assembly design.

Machine guards and access covers can use a prepared seat when slip control matters and an external screw head is not wanted. Check mating feature, hex access, screw length, and marking tolerance. Cold Headers can review non-catalog pelletized set screw requests when the item must retain half dog point geometry.

Cold Headers works with distributors, OEM teams, and maintenance programs that need exact socket set screw configurations. Review insert dimensions, hex key size, and ASME B18.3 before ordering this alloy steel socket set screw.
