For finished parts that need a softer bearing face, 1/2-13 x 1/2 supplies an alloy steel socket set screw with a nylon tip matched to the row's verified dimensions.
Typical uses include machine-tool stops on finished ways, fixture pads, and locating features used during setup. The 3A thread fit keeps the screw in the precision set-screw class while the tip changes the way the end contacts the part. Nylon is the softer contact choice for delicate finishes and repeated adjustment.
The Chicago tip-installation service lets Cold Headers support both catalog tipped screws and related cap screw tipping work. For humid or washdown service, compare the Nylon and Brass Tip 18-8 Stainless Socket Set Screws family; this page remains the alloy-body route.
