1/4-28 x 1/4 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is suited to collars, knobs, and stops that may be loosened, rotated, and reset during service. Oval point geometry favors adjustable contact and re-seating rather than maximum bite into the mating part. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.

Typical uses include adjustment collars that are repositioned between production runs without changing the basic hardware.

Cold Headers focuses on exact-size socket fastener sourcing for production cells, repairs, and plant maintenance programs. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution. Socket-key access remains compact when the screw sits below the outside surface of a collar or hub.
