3/8-16 x 5/8 supports positioning and retention tasks where the drawing calls out a nylon tipped socket set screw instead of a bare alloy point.
Typical uses include jig and fixture adjustment, workholding details, and service parts that return to the same location. The soft tip concentrates contact at the end of the screw while avoiding the harsher bite of an untreated alloy point. Nylon is the softer contact choice for delicate finishes and repeated adjustment.
Cold Headers installs nylon and brass tips at its Chicago facility for set screws and cap screws when a tipped configuration is required. A nylon insert acts on the thread; a nylon or brass tip acts on the mating surface, so the two product families should not be substituted blindly.
