1/4-20 x 1/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert uses two locking interfaces in one headless fastener. 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.
Typical uses include marine-adjacent hardware after chloride review, collars, and component retention, where the set screw must hold position without an external head. If an all-metal holding feature is preferred, review Knurled Point 18-8 Socket Set Screws for mechanical ratchet-style grip.
