The VALUE COLLECTION R63003640 is a hex socket cap screw designed for secure fastening in applications requiring corrosion resistance and precise torque control. Threaded to 5/16-18 UNC with a 1/2-inch length under head, this screw accepts a 1/4-inch hex drive. It is manufactured from Grade 316 stainless steel, making it well suited for marine, chemical, food-service, and outdoor environments where moisture or corrosive media are present. Machinists, maintenance technicians, and fabricators install these fasteners wherever a socket head drive style is required over a standard hex bolt.
This screw fits standard 5/16-18 UNC tapped holes and is appropriate for light to medium structural fastening in both residential and commercial applications. The socket cap head profile allows installation in recessed or tight-clearance locations where a wrench cannot reach. Typical uses include equipment enclosures, machine frames, brackets, and fixtures. Sold as a single piece with a minimum order quantity of 10 units.
Designed as a standard replacement or new-installation hex socket cap screw for any application specifying a 5/16-18 UNC thread pitch and a 1/2-inch length under head in 316 stainless steel.
Installation is performed with a 1/4-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Apply thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling. Do not exceed the torque rating appropriate for 5/16-18 stainless steel fasteners as specified by the equipment manufacturer or applicable fastener standards.
