8-32 x 1/2 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. Use 18-8 stainless where the drawing calls for stainless material in indoor machinery, washdown-adjacent equipment, or humid service.
Typical uses include outdoor equipment linkages, adjustable stops, and service hardware, where the set screw must hold position without an external head. A nylon tip protects the shaft surface from marring, while a nylon insert locks the screw in its thread; those are different features.
Cold Headers has supplied specialty socket fasteners since 1962 and helps confirm exact set screw sizes for drawings and repairs. 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.
