Use the 4-40 x 5/16 full dog point 18-8 stainless socket set screw when a component must seat in a prepared hole or milled slot. The pilot end locates the part rather than biting or indenting the mating surface.

Common application reviews include positioning parts that must be removable without shaft damage. Compared with a flat point, the full dog point is used when the assembly needs pilot-tip engagement rather than broad bearing on a finished surface.

18-8 stainless steel is an 18% chromium and 8% nickel austenitic stainless material referenced to ASTM F880 for general plant environments, moisture exposure, and clean appearance. Cold Headers' socket-fastener focus is useful when thread, length, material, and point style must line up precisely.
