5/16-18 x 1/2 Cone Point Alloy Steel Socket Set Screw with Nylon Insert combines heat-treated alloy steel construction, internal hex drive access, and a nylon insert in one cone-point set screw. The nylon insert does not contact the shaft; it works in the female thread to add friction during installation and removal. Use this alloy steel body with the nylon locking pellet where the drawing calls for a mechanical set screw, not a corrosion-focused stainless part.
Replacement assemblies with dimpled shafts can keep the original point style while adding a nylon insert for thread friction.
Cold Headers can help source hard-to-find cone point nylon-insert set screws while preserving the exact SKU requirement. Review thread size, length, hex key size, point style, and mating-surface marking tolerance before replacing it with another set screw. The internal hex recess also keeps installation access compact when the screw is recessed in a hub or collar.
