6-32 x 5/8 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert is built for a properly cut 82-degree countersink where the head can sit flush or slightly below the surface. When installed in the correct countersink, the flat head leaves little exposed hardware for covers, panels, or moving material to catch.

For walk plates, step surfaces, or low-snag equipment panels, 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.

Because the locking element is nylon, confirm the service temperature separately from the stainless screw selection; this listing does not state a limit. Cold Headers can help verify the exact 18-8 flat head nylon-insert configuration before quoting pricing and availability.
