8-32 x 3/8 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert is measured overall, so the listed length includes the flat head. Flat head screw lengths are measured overall, head included, so this listed length is the total installed screw length. The 82-degree flat head needs a matching countersink cut cleanly and concentrically so the cone bears correctly and the head seats true.

In food equipment surfaces, wipe-down panels, or stainless guards, 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.

Slight magnetism from cold working can be normal for 18-8 stainless, so final material selection should reflect the assembly conditions. The locking pellet is installed in-house on supported socket-cap sizes, with unusual requests handled through quoting.
