Value Collection HCI20620250G-025BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI20620250G-025BX is a 5/8-11 UNC hex head bolt with a 2-1/2 inch length under head, manufactured from Grade 2 steel with a hot-dipped galvanized finish. Designed for general structural and mechanical fastening applications, this partially threaded bolt meets ASTM A307 standards, making it suitable for low-carbon steel fastener applications where moderate tensile strength and corrosion resistance are required. The hot-dipped galvanized coating provides a durable layer of zinc protection against rust and environmental exposure. Tradespeople and contractors rely on this bolt type for structural assemblies, framing connections, and equipment mounting in both indoor and outdoor settings.

This bolt is suited for general construction, mechanical, and industrial fastening tasks. The partial threading allows for a smooth shank section that resists shear loading in bolted connections. At 5/8-11 UNC thread size and 2-1/2 inches in length under head, it fits standard hex nuts and flat washers in common structural applications. Typical installation scenarios include wood-to-steel connections, equipment bases, support brackets, and general structural framing where galvanized fasteners are specified for corrosion resistance.

Key Features

• 5/8-11 UNC thread size with partial threading for shear-capable bolted connections
• 2-1/2 inch length under head for standard structural fastening depth
• Hot-dipped galvanized finish provides corrosion resistance in outdoor and wet environments
• Grade 2 steel construction meets ASTM A307 fastener standard
• Inch measurement system, compatible with standard SAE hex nuts and washers

Compatibility

Designed as an OEM-style replacement or general-use hex head bolt compatible with standard 5/8-11 UNC hex nuts, flat washers, and lock washers in structural and mechanical fastening applications.

Installation Notes

Installation is typically performed by carpenters, ironworkers, millwrights, or general contractors using standard hand or power tools with the appropriate 15/16 inch hex socket or wrench. Tighten fasteners to the torque specification required by the governing structural or mechanical standard for the application. Follow applicable building codes and AISC or IBC guidelines when using bolts in structural steel connections. Do not reuse bolts that have been overtorqued or show signs of thread damage or corrosion.
