10-24 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 inch-series flat head angle is 82 degrees; metric flat heads are commonly 90 degrees, so the countersink angle should be checked before substitution.
In food equipment surfaces, wipe-down panels, or stainless guards, the internal hex drive supports top-side installation after the countersink is prepared. Plain 18-8 Stainless Flat Head Socket Cap Screws may fit torque-once joints where a nylon insert is not required.
The nylon pellet presses against the mating thread to provide prevailing torque without changing the countersunk head geometry. For supported flat head cap-screw requests, nylon inserts are installed in-house at the Chicago facility.
