1/4-28 x 1 1/4 316 Stainless Steel Flat Head Socket Cap Screw supports flush-mounted construction in equipment that must be handled, wiped down, or positioned near moving components. Countersunk seating allows covers and plates to close cleanly without raised hardware disrupting the surface. 316 stainless steel supports demanding service around salt spray, cleaning fluids, and many industrial washdown environments. The internal drive supports controlled torque application in panels, housings, and cover plates. It may be used on food and beverage machinery, inspection plates, and washdown-compatible equipment assemblies. OEM manufacturers can document the exact size while keeping stainless flat head hardware consistent across builds. The listing helps buyers match a required thread and size without changing the assembly design. Call Cold Headers at 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote.
