Value Collection HCI20500175-050BX Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION HCI20500175-050BX is a 1/2-13 hex head bolt designed for general-purpose fastening in mechanical, structural, and trade applications. It features a partially threaded shank with a 1-3/4 inch length under head, manufactured from Grade 2 uncoated steel and certified to ASTM A307. The UNC (Unified National Coarse) thread form is the standard for most inch-system fastening work. This bolt is sold in a minimum order quantity of 50 units, making it practical for contractors and tradespeople stocking common fastener sizes. HVAC, plumbing, and electrical contractors regularly use Grade 2 hex bolts for equipment mounting, panel support, and structural attachment work.

This bolt is suited for light to moderate structural and mechanical fastening in residential and commercial construction environments. The partially threaded design provides a smooth shank section near the head, which is useful when a bearing surface or shear resistance is needed between joined materials. Applications include equipment bases, framing connections, ductwork supports, electrical panel mounting, and general utility fastening where ASTM A307 Grade 2 compliance is acceptable. The uncoated bright finish is appropriate for indoor or protected installations where corrosion exposure is minimal.

Designed as a standard inch-system hex head bolt suitable for use with 1/2-13 UNC nuts, washers, and tapped components meeting ASTM A307 Grade 2 requirements in general mechanical and structural fastening assemblies.

Installation Notes

Hex head bolts of this type are installed by general contractors, HVAC technicians, plumbers, and electricians during equipment mounting and structural attachment work. Use an appropriate wrench or socket driver sized for a standard 1/2-13 hex bolt head. Follow applicable building codes and equipment manufacturer torque guidelines when specified. Do not use in applications requiring higher-grade fastener standards such as ASTM A325 or A490 without confirming ASTM A307 Grade 2 is acceptable for the load case.
