1/2-20 x 1/2 Flat Point Alloy Steel Socket Set Screw with Nylon Insert provides flat-face contact for controlled friction hold in machinery where shaft scarring is a concern. The internal hex drive keeps the screw headless and accessible in collars, hubs, and compact machine details. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.

Instrument and control components may need the no-mark behavior of a flat point along with an internal hex drive. When maximum bite matters more than shaft protection, compare Cup Point Alloy Set Screws with Nylon Insert.

For replacement work, Cold Headers helps keep thread, length, material story, point style, and insert function aligned. Check thread size, length, socket size, pellet dimensions, shaft-flat condition, and surface-marking tolerance before substitution.
