1/2-13 x 1/4 316 Stainless Steel Flat Head Socket Cap Screw is designed for finished assemblies where a smooth surface reduces catching points and improves service access. Countersunk installation can make maintenance areas cleaner and reduce catching points around removable covers. Its chloride resistance is valuable for marine hardware, pump covers, valve covers, and exposed equipment panels. The drive style gives OEM manufacturers a repeatable installation method for countersunk stainless hardware. The product suits coastal equipment, valve covers, OEM housings, and instrument panels where corrosion resistance matters. Distributors and OEM buyers can align the FHCS-316 designation with 316 stainless flat head socket cap screw inventory. It also supports standardization across related covers, guards, and enclosure assemblies. Call Cold Headers at 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote.
