4-40 x 1/8 is a nylon tip alloy steel socket set screw built for set-screw fastening where a soft contact face is preferred over a hardened point.

Typical uses include polished shaft collars, small hubs, and replacement collars on finished round stock. 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. The soft tip concentrates contact at the end of the screw while avoiding the harsher bite of an untreated alloy point.
