6-32 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 a low-profile head without cutting a countersink, compare 18-8 Button Head Socket Cap Screws with Nylon Insert.
The nylon pellet presses against the mating thread to provide prevailing torque without changing the countersunk head geometry. Cold Headers can handle supported non-catalog pellet-size requests through in-house pelletizing.
