5/16-24 x 1/4 Flat Point Alloy Steel Socket Set Screw with Nylon Insert gives purchasing teams a specific alloy steel flat point nylon-insert size for replacement work. Because the point does not dig in by design, final holding action depends on the surface condition, load, and seating area. Use the heat-treated alloy steel body with the nylon locking pellet where the application calls for mechanical fastening rather than stainless material.
Drive collars and light hub assemblies may specify this style when shaft protection matters more than a point bite.
The nylon pellet is added to create thread drag while leaving the flat bearing face responsible for shaft contact. 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.
