Value Collection HCI20500175G-050BX Hex Head Bolt 1/2-13

Product Description

The VALUE COLLECTION HCI20500175G-050BX is a Grade 2 galvanized steel hex head bolt with a 1/2-13 UNC thread and a 1-3/4 inch length under head. It is partially threaded and carries an ASTM A307 designation, making it appropriate for general structural and mechanical fastening applications where a hot-dipped galvanized finish is required for corrosion resistance. This bolt is sold in a minimum order quantity of 50 units per box. It is a standard inch-system fastener installed by contractors, maintenance technicians, and tradespeople across construction, mechanical, and industrial service work.

This bolt is suited for use in general construction, structural connections, and equipment assembly where corrosion resistance is a priority. The hot-dipped galvanized finish provides a durable zinc coating that holds up in outdoor, wet, and moderately corrosive environments. Partial threading allows the unthreaded shank to bear shear loads in lap joints and bolted connections. ASTM A307 Grade 2 covers bolts intended for general-purpose use in non-critical structural and mechanical assemblies.

Installation Notes

Installation is performed by qualified tradespeople using standard hex wrenches or impact tools appropriate for 1/2-inch fasteners. Confirm hole clearance and thread engagement before final tightening. Follow applicable building codes or structural specifications for proper torque and joint requirements. Do not substitute Grade 2 hardware in applications that specify higher-grade fasteners such as Grade 5 or Grade 8.
