5-40 x 5/8 Oval Point Alloy Steel Socket Set Screw with Nylon Insert is a compact locking set screw for parts that need internal hex access and a rounded contact point. The internal hex drive keeps the screw headless and accessible in collars, hubs, handles, and compact control parts. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.

Linkage and lever assemblies may use this point style where the screw meets the mating part at an odd angle.

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.
