The VALUE COLLECTION C703316 is a 9/16-12 x 3-inch hex head cap screw manufactured from Grade 8 steel in an uncoated finish. It features partial threading and conforms to ASME B18.2.1 standards, making it a reliable fastener for high-strength bolted connections in industrial, mechanical, and structural applications. The Unified National Coarse (UNC) thread form ensures broad compatibility with standard nuts and tapped holes. Licensed tradespeople and maintenance technicians rely on Grade 8 hardware when joints require elevated tensile and proof load ratings compared to lower-grade alternatives.
This fastener is suited for use in heavy equipment assembly, structural steel connections, machinery mounting, and general mechanical fabrication where high-strength fastening is required. The partially threaded shank provides a smooth bearing surface in the grip zone, reducing stress concentration in shear-loaded joints. Sold in a package quantity of 25, the C703316 is appropriate for both single-repair tasks and small-batch production work in shops and field service environments.
Designed as a standard 9/16-12 UNC hex head cap screw suitable for use with any 9/16-12 threaded nut or tapped hole conforming to ASME B18.2.1 specifications in inch-measurement fastener applications.
Installation should be performed by a qualified mechanic or maintenance technician using a properly rated hex socket or open-end wrench. Always verify the mating thread and material specifications before installation to ensure grade compatibility with the joint design. Derate the connection appropriately when installing into softer base materials. Follow applicable industry torque guidelines for Grade 8 fasteners based on joint design requirements.
