1/4-20 x 5/8 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert places the cup rim at the workpiece and the nylon insert at the mating thread. The point focuses contact at the work surface, and the pellet creates prevailing torque after the screw is driven into the tapped hole. Slight magnetism from cold working can be normal for 18-8 stainless, so verify the material requirement against the actual assembly.
Typical uses include pulleys and sprockets in humid plants, light drives, and hub 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.
Since 1962, Cold Headers has helped industrial buyers locate specialty socket products and replacement 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.
