6-32 x 1 1/2 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert helps avoid length-selection errors common when switching from socket head cap screws. For example, a 1/4-20 x 1 flat head screw fits within one inch overall because the head is included in that length. A countersunk head bears on the cone rather than a broad underside, so clamp load should not be treated like a full socket head cap screw.

For display faces, fixture panels, or visible stainless hardware, confirm countersink geometry, thread engagement, and whether the nylon insert suits the service conditions. Plain 18-8 Stainless Flat Head Socket Cap Screws may fit torque-once joints where a nylon insert is not required.

The 18% chromium and 8% nickel austenitic stainless material is commonly selected for general corrosion resistance, clean appearance, and ordinary washdown exposure. For supported flat head cap-screw requests, nylon inserts are installed in-house at the Chicago facility.
