5/16-24 x 3/8 is specified for dry-service set-screw work where the screw must hold adjustment while reducing direct steel-on-part contact.
Typical uses include semiconductor tooling, electronics fixtures, and light mechanical assemblies with finished contact surfaces. 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 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.
