1/4-28 x 5/16 Oval Point Alloy Steel Socket Set Screw with Nylon Insert provides smooth point contact for mechanisms where the approach angle changes from one setup to another. The internal hex drive keeps the screw headless and accessible in collars, hubs, handles, and compact control parts. Specify the heat-treated alloy steel body with nylon pellet when the print calls for mechanical set screw hardware, not a stainless substitute.
Spline-adjacent and keyway-adjacent seating may call for a rounded point where sharp engagement would be too aggressive. Plain Oval Point Alloy Socket Set Screws may fit the job when the nylon insert is not required.
Cold Headers installs nylon locking pellets in-house at its Chicago facility for this oval point set screw family. For replacement work, Cold Headers keeps the thread, length, alloy material, rounded point, and insert requirement together. Check thread size, length, socket size, pellet dimensions, groove or seat condition, and surface-marking tolerance before substitution.
