1/4-20 x 5/8 316 Stainless Steel Flat Head Socket Cap Screw provides recessed attachment for OEM machinery, instrumentation faces, and enclosure panels exposed to demanding environments. The flat head profile is useful where exposed screw heads would create clearance problems or trap residue. 316 stainless steel provides excellent corrosion resistance for marine equipment, coastal installations, and saltwater environments. Internal hex drive access is useful in compact equipment where a clean outside face still needs secure tightening. It may be used on food and beverage machinery, inspection plates, and washdown-compatible equipment assemblies. Distributors and OEM buyers can align the FHCS-316 designation with 316 stainless flat head socket cap screw inventory.
