8-32 x 3/8 18-8 Stainless Steel Button Head Socket Cap Screw with Nylon Insert is a compact socket-driven fastener for joints where a separate washer or adhesive is not desired. Its insert creates thread-friction resistance to backing out under vibration without requiring a separate locking washer.
The rounded button head can reduce exposed edges, spread bearing load over a broader face, and avoid counterbore machining when the assembly accepts a raised dome. In electronics enclosures, cabinet covers, or instrument panels, the internal hex drive supports top-side installation while the rounded head reduces surface projection.
The 18% chromium and 8% nickel austenitic stainless material is commonly chosen for general corrosion resistance, clean appearance, and ordinary moisture exposure. Plain 18-8 Button Head Socket Cap Screws may fit torque-once joints where the nylon insert is not required. Cold Headers supports distributors, maintenance teams, and OEM sourcing work when a precise button-head nylon-insert configuration is needed.
