1/4-28 x 1 1/4 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. Nylon and brass tips serve different jobs: nylon gives the softer touch, while brass provides a firmer metallic face. Nylon is the softer contact choice for delicate finishes and repeated adjustment.
Cold Headers is a useful source when the drawing calls for a less common tipped set screw length or fine-thread alloy body. For thread locking rather than surface protection, Alloy Set Screws with Nylon Insert solve a different job than nylon or brass tip screws.
