1/4-20 x 1/2 18-8 Stainless Steel Flat Head Cap Screw with Nylon Insert combines stainless material, internal hex drive access, and a nylon locking pellet. When installed in the correct countersink, the flat head leaves little exposed hardware for covers, panels, or moving material to catch. Flat head screw lengths are measured overall, head included, so this listed length is the total installed screw length.
This size is often reviewed for packaging machinery guards, changeover plates, and transfer covers 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.
Because the locking element is nylon, confirm the service temperature separately from the stainless screw selection; this listing does not state a limit. Since 1962, Cold Headers has helped distributors, repair teams, and OEM sourcing projects locate specialty socket products.
