8-32 x 1/4 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert uses an 82-degree countersunk head for fastening where surface projection must be minimized. The 82-degree flat head needs a matching countersink cut cleanly and concentrically so the cone bears correctly and the head seats true.
Typical applications include sliding machine covers, flush access panels, and service plates, where nothing proud should catch passing material or hands. For a low-profile head without cutting a countersink, compare 18-8 Button Head Socket Cap Screws with Nylon Insert.
Slight magnetism from cold working can be normal for 18-8 stainless, so final material selection should reflect the assembly conditions. Cold Headers has supported specialty socket fastener sourcing since 1962, including exact stainless sizes and uncommon lengths.
