The VALUE COLLECTION 403290BR is a partially threaded hex head cap screw designed for general-purpose fastening applications in mechanical assemblies, structural connections, and equipment fabrication. Built to Grade 2 steel specifications, this fastener measures 3/4-10 UNC thread by 5-1/2 inches under the head and carries a zinc plating for basic corrosion resistance. The 1-1/8-inch hex key size accommodates standard open-end, box-end, or socket wrenches. Partial threading provides a smooth shank section that resists shear loads and allows for controlled clamping in bolted joint assemblies. Suitable for a wide range of light-to-medium duty fastening tasks encountered in the field or shop.
This screw is commonly used in residential and commercial construction, HVAC equipment mounting, plumbing fixture support, electrical enclosure assembly, and general mechanical fabrication. Its 3/4-10 UNC thread is among the most widely standardized coarse-thread sizes in inch-system hardware, making it compatible with a broad inventory of nuts, washers, and tapped components already in use across trade applications. Zinc plating offers adequate corrosion protection for interior and sheltered exterior installations. Sold individually; minimum order quantity is 10 pieces.
Designed as a standard inch-system hex head cap screw compatible with 3/4-10 UNC nuts, flat washers, lock washers, and tapped holes conforming to UNC thread standards.
Installation is performed by machinists, maintenance technicians, electricians, plumbers, and HVAC mechanics using standard open-end, box-end, or socket wrenches sized to 1-1/8 inches. Always ensure the mating thread or tapped hole is clean and free of debris before installation. Verify material and grade suitability for the load and environmental conditions of the specific application before use. Do not apply excessive torque beyond the design limits of Grade 2 steel fasteners.
