Value Collection HCI20500125G-050BX Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION HCI20500125G-050BX is a fully threaded hex head bolt designed for general structural and mechanical fastening applications. Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt meets ASTM A307 standards for low-carbon steel fasteners. The 1/2-13 UNC thread and 1-1/4 inch length under head make it a common choice for light-to-medium structural connections, equipment mounting, and general assembly work. Licensed contractors, millwrights, and maintenance technicians keep this size on hand for everyday fastening tasks where corrosion resistance is required.

This bolt is suited for outdoor, damp, or mildly corrosive environments where a galvanized coating provides adequate protection. The fully threaded shank allows engagement along the entire length of the fastener, which is useful when joining thinner materials or when full thread engagement in a nut or tapped hole is needed. Typical applications include general construction framing connections, equipment bases, brackets, and structural steel assemblies where ASTM A307 Grade 2 compliance is specified. This SKU ships in a minimum order quantity of 50 units per box.

Compatibility

Designed as a standard 1/2-13 UNC fully threaded hex head bolt for use with any standard 1/2-13 hex nut or tapped hole conforming to UNC inch-series thread specifications.

Installation Notes

Installation is performed by mechanics, ironworkers, or maintenance technicians using a standard 3/4 inch hex wrench, socket, or impact driver. Always verify that mating nuts or tapped holes are also rated to ASTM A307 or equivalent and are the correct UNC thread series before installation. Torque to fastener manufacturer or project specification requirements — do not over-torque Grade 2 hardware, as it has lower proof and tensile strength than Grade 5 or Grade 8. Inspect galvanized coating for damage before installation; nicked or bare areas in corrosive environments should be treated with cold galvanizing compound.
