1/4-20 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. For a low-profile head without cutting a countersink, compare 18-8 Button Head Socket Cap Screws with Nylon Insert.
Because the locking element is nylon, confirm the service temperature separately from the stainless screw selection; this listing does not state a limit. The locking pellet is installed in-house on supported socket-cap sizes, with unusual requests handled through quoting.
