1/4-28 x 1 Oval Point Alloy Steel Socket Set Screw with Nylon Insert gives designers a rounded-contact set screw for shafts, grooves, and seats that may not be perfectly square. 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.

Spline-adjacent and keyway-adjacent seating may call for a rounded point where sharp engagement would be too aggressive.

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.
