For finished parts that need a softer bearing face, 4-40 x 3/16 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. Buyers should confirm the tip material, thread fit, thread size, and threaded body length against the drawing before substitution. Nylon is the softer contact choice for delicate finishes and repeated adjustment.
Cold Headers supports set-screw users with application-aware sizing help and a catalog built around specialty socket products. That makes it useful when the set screw must bear on a finished or plated part and later be adjusted again.
