5/16-18 x 1 1/2 is an alloy steel socket set screw fitted with a nylon tip for machinery and tooling locations where surface marking must be controlled.

Typical uses include anodized frames, plated components, and other assemblies where a softer contact face is useful. 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. When the need is a self-locking thread element, compare Alloy Set Screws with Nylon Insert instead of a surface-protecting tip screw.
