Value Collection 403312BR Hex Head Cap Screw 7/8-9 X 2-3/4 in

Product Description

The VALUE COLLECTION 403312BR is a fully threaded hex head cap screw designed for general-purpose fastening in industrial, mechanical, and structural applications. It measures 7/8-9 (7/8 inch diameter, 9 threads per inch) with a 2-3/4 inch length under head and follows the UNC (Unified National Coarse) thread standard. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener provides basic corrosion resistance suitable for indoor and mild-exposure environments. The 1-5/16 inch hex key size accommodates standard wrenches for installation and removal. Sold individually with a minimum order quantity of 10 pieces.

This screw is suited for light-to-medium duty assemblies where a full-thread grip length is required across the entire fastened joint. Common applications include mechanical equipment frames, brackets, utility fixtures, and general maintenance repairs in commercial and industrial settings. The UNC thread form is widely compatible with standard tapped holes and hex nuts in inch-measurement systems, making this fastener a practical stock item for maintenance technicians, millwrights, and mechanical contractors.

Installation Notes

Installation is performed with a standard 1-5/16 inch open-end, box-end, or socket wrench. Ensure mating threads are clean and free of debris before assembly. Follow applicable torque guidelines for Grade 2 steel fasteners as specified by the equipment manufacturer or applicable mechanical codes. Avoid overtightening, which can strip threads or yield the fastener shank.
