1/4-20 x 1 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert supports flush stainless fastening where vibration can work on the threaded joint. The 82-degree flat head needs a matching countersink cut cleanly and concentrically so the cone bears correctly and the head seats true. A buyer moving from socket head cap screws should remember that flat heads are not measured from under the head.
In electronics enclosures, flush cabinet faces, or control panels, the internal hex drive supports top-side installation after the countersink is prepared. For higher preload potential and a deeper socket, review 1960 Series 18-8 SHCS with Nylon Insert.
The 18% chromium and 8% nickel austenitic stainless material is commonly selected for general corrosion resistance, clean appearance, and ordinary washdown exposure. Cold Headers helps industrial buyers confirm hard-to-find countersunk socket fastener sizes for maintenance and production work.
