1/4-28 x 1 1/2 316 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 high-humidity facilities, stainless housings, and equipment panels where stainless corrosion resistance and internal-hex access are practical. Manufacturing facilities can standardize this size where corrosion-resistant socket-drive hardware is required.
