Value Collection 403202PR Hex Cap Screw 1/2-13 X 3-3/4 in Grade 2

Product Description

The VALUE COLLECTION 403202PR is a partially threaded hex head cap screw designed for general-purpose fastening in structural, mechanical, and industrial assemblies. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener provides reliable corrosion resistance in typical indoor and light-duty outdoor applications. The 1/2-13 thread size follows the Unified National Coarse (UNC) standard, and the 3-3/4-inch length under head accommodates a range of through-bolting and clamping applications. The partial threading allows the unthreaded shank to bear shear loads, making it suitable where shank engagement is important to joint integrity.

This hex cap screw is commonly used in light structural fabrication, equipment mounting, machinery assembly, and maintenance and repair operations (MRO) across a wide range of trades. The 1/2-13 UNC thread pattern is one of the most widely standardized sizes in inch-system fastening, making it readily compatible with standard hex nuts, locknuts, and threaded inserts found in commercial and industrial equipment. A 3/4-inch hex key drive allows installation with standard open-end, box-end, or socket wrenches.

Key Features

• 1/2-13 UNC thread meets Unified National Coarse inch-system standards
• Partial threading allows the shank to carry shear loads in bolted joints
• Grade 2 steel construction suitable for general-purpose, non-critical fastening
• Zinc-plated finish provides basic corrosion protection for light-duty service environments
• 3/4-inch hex drive compatible with standard wrenches and sockets

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1/2-13 UNC threaded nuts, inserts, and tapped holes conforming to Unified National Coarse thread specifications.

Installation Notes

Installation is performed with a 3/4-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 fasteners as specified by the applicable engineering standard or equipment manufacturer. Do not use impact tools at full torque without a torque-limiting socket to avoid overloading the Grade 2 material.
