Value Collection HHCSI20500200-025BX Hex Head Bolt

Product Description

The VALUE COLLECTION HHCSI20500200-025BX is a 1/2-13 UNC hex head bolt with a 2-inch length under head, manufactured from uncoated steel to ASTM A307 specifications. This is a partially threaded fastener, meaning the shank near the head remains unthreaded, which helps resist shear forces in structural and mechanical connections. Grade A307 designates low-carbon steel with defined tensile strength requirements, making it a standard choice for general-purpose bolted assemblies in construction, mechanical, and utility applications. Tradespeople and contractors select this bolt when an A307-compliant fastener is called out on drawings or specifications.

This bolt is suited for residential and commercial construction framing, structural steel connections, mechanical equipment mounting, and general-purpose fastening applications where ASTM A307 compliance is required. The 1/2-13 thread size is one of the most common UNC fastener sizes used by plumbers, pipefitters, electricians, and general contractors for pipe hangers, equipment supports, brackets, and unistrut connections. The uncoated bright finish is appropriate for interior or protected installations. This SKU is sold in a minimum order quantity of 25 bolts.

Key Features

• ASTM A307 Grade A307 low-carbon steel construction meets defined tensile requirements for general-purpose structural use
• Partially threaded shank provides shear resistance in bolted joint applications
• 1/2-13 UNC thread form is the industry-standard coarse thread for this diameter
• 2-inch length measured under head accommodates common stack-up thicknesses in structural and mechanical assemblies
• Uncoated bright finish suits interior and dry-environment installations
• Sold in multiples of 25, reducing per-unit cost for service and installation jobs

Compatibility

Designed as a general-purpose hex head bolt for use in any application calling for a 1/2-13 UNC partially threaded fastener meeting ASTM A307 Grade A307 requirements.

Installation Notes

Installation is performed by carpenters, ironworkers, pipefitters, electricians, and other trades using standard 3/4-inch drive or hand tools sized for a 1/2-inch hex bolt. Always confirm that the mating nut, washer, and base material are rated to match or exceed the A307 grade before assembly. Follow applicable building codes and torque requirements specified by the engineer of record or equipment manufacturer, as none are defined by this product listing alone. Do not substitute this uncoated fastener in exterior or corrosive environments without verifying finish suitability.
