10-24 x 2 1/4 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert should be ordered by total screw length because the head is part of the measurement. Overall-length measurement matters on countersunk joints because the head occupies part of the thickness stack. When installed in the correct countersink, the flat head leaves little exposed hardware for covers, panels, or moving material to catch.

This size is often reviewed for washdown covers, processing guards, and inspection doors when stainless material, a flush head, and locking friction are all specified. For higher preload potential and a deeper socket, review 1960 Series 18-8 SHCS 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. For supported flat head cap-screw requests, nylon inserts are installed in-house at the Chicago facility.
