5/16-24 x 5/8 Cone Point Alloy Steel Socket Set Screw with Nylon Insert is a heat-treated alloy steel cone point socket set screw with a nylon insert for thread drag after seating. 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.
Automation equipment may use this screw in compact hubs, guide collars, and actuator-linked parts with limited outside clearance.
Cold Headers supports exact-size and hard-to-find cone point nylon-insert sourcing for industrial repair, replacement, and production requirements. 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.
