3/8-16 x 1/2 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert pairs a cup point for shaft contact with a nylon pellet in the thread. The cup point's hollow rim bears on the shaft or mating part, while the nylon insert presses against the female thread to help resist back-out. For final material selection, consider moisture, cleaning exposure, mating material, and whether 18-8 is suitable for the service conditions.
In food and beverage machinery adjustments, changeover stops, and equipment guards, the internal hex drive allows adjustment from the end of the tapped hole. If an all-metal holding feature is preferred, review Knurled Point 18-8 Socket Set Screws for mechanical ratchet-style grip.
Cold Headers supports hard-to-find socket set screw sourcing, including uncommon lengths and nylon-insert configurations. Review the thread size, length, hex key size, point style, and set-screw pellet location before matching the part to a service record or drawing.
