1/4-20 x 3/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert is a headless socket set screw for compact shaft and component retention. The point focuses contact at the work surface, and the pellet creates prevailing torque after the screw is driven into the tapped hole. 18-8 stainless steel is commonly selected for clean appearance, general corrosion resistance, and ordinary moisture exposure.
For packaging equipment, indexing stops, or machine adjustments, check point contact, threaded engagement, and drive access before installation. If shaft protection matters more than cup-point bite, Nylon and Brass Tip 18-8 Socket Set Screws solve a different problem than nylon inserts. This 18-8 family is not a heat-treated alloy-steel substitute; review the alloy version where seating torque is the priority.
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.
