1/2-13 x 3 316 Stainless Socket Head Cap Screw provides a 316 stainless socket-drive fastener for production hardware exposed to water, humidity, or corrosive industrial conditions. 316 stainless steel is commonly chosen for better chloride resistance than general-purpose stainless grades. The drive style is useful when repeated maintenance requires controlled removal and reinstallation. Typical placements include assembly systems, stainless brackets, and manufacturing facilities where stainless corrosion resistance and internal-hex access are practical. Manufacturing facilities can standardize this size where corrosion-resistant socket-drive hardware is required.
