1/4-28 x 3/8 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 rounded oval point can make tangent contact on flat, angled, curved, or grooved mating surfaces. 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 can help identify the correct rounded-point alloy set screw when a drawing calls out a nylon insert. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
