For compact assemblies without an external screw head, 1/4-28 x 5/8 provides an internal-socket set screw with a nylon tip for controlled contact.

Typical uses include maintenance repairs, retrofit stops, and machine rebuilds where matching the original tip material matters. Because the tip is the contact element, the mating material and acceptable witness mark should guide final selection. Nylon is the softer contact choice for delicate finishes and repeated adjustment.

Cold Headers has supplied specialty socket fasteners since 1962 and keeps this category focused on exact size, tip material, and application fit. For maximum bite instead of surface protection, the related cup point alloy set screw family is the better comparison.
