1/4-28 x 1/4 Cup Point 18-8 Stainless Steel Socket Set Screw with Nylon Insert is selected where a stainless cup point set screw also needs a thread-locking pellet. This double-lock arrangement separates the shaft-holding role of the cup point from the thread-locking role of the nylon insert. 18-8 stainless steel is commonly selected for clean appearance, general corrosion resistance, and ordinary moisture exposure.

In instrumentation knobs, stainless stops, and control components, the internal hex drive allows adjustment from the end of the tapped hole. 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.

For distributors, OEM sourcing, and maintenance work, Cold Headers can help match the thread, length, point style, material, and insert location. 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.
