The VALUE COLLECTION HCI20430450G-025BX is a Grade 2 steel hex head bolt with a 7/16-14 UNC thread and a 4.5-inch length under head. It features a hot-dipped galvanized finish that provides corrosion resistance in exterior and wet environments. The bolt is partially threaded, making it well suited for clamping applications where a smooth shank is required in the grip area. This fastener conforms to ASTM A307 standards and is sold in minimum order quantities of 25 pieces. It is a standard inch-system fastener used by tradespeople across HVAC, plumbing, electrical, and general construction applications.
This bolt is appropriate for light- to medium-duty structural and mechanical connections in both residential and commercial settings. The hot-dipped galvanized coating makes it a practical choice for outdoor installations, treated lumber connections, and other corrosive environments where plain steel fasteners would degrade prematurely. Electricians, plumbers, and HVAC technicians commonly use this bolt size when securing equipment supports, hangers, and brackets to structural members.
Designed for use with standard 7/16-14 UNC hex nuts and washers in inch-system mechanical and structural assemblies.
Install with an appropriate 7/16-inch drive socket or wrench. Use flat washers and a properly rated nut to distribute load and achieve full clamping force. Follow applicable building or mechanical codes, such as the IBC or IFGC, for torque and connection requirements specific to the application. Do not reuse fasteners that have been overtightened, visibly damaged, or exposed to high heat.
