Value Collection R52001258 Hex Head Bolt 5/8-11 3in Grade 2

Product Description

The VALUE COLLECTION R52001258 is a 5/8-11 UNC hex head bolt manufactured from Grade 2 steel with a hot-dipped galvanized finish. The bolt measures 3 inches under the head and features partial threading, making it well suited for through-bolt and clamping applications where a smooth shank is required in the grip area. The 15/16-inch hex drive allows use with standard wrenches and impact tools. This fastener meets ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2 dimensional standards. Installers working in plumbing, HVAC equipment mounting, structural framing, or general mechanical assembly will find this a straightforward, code-compliant bolt for light-to-medium duty connections.

This bolt is appropriate for residential and light commercial applications requiring a corrosion-resistant fastener. The hot-dipped galvanized coating provides durable protection in outdoor, damp, or exposed environments such as equipment pads, pipe hangers, structural connections, and utility mounting. Partial threading suits applications where shank bearing is preferred over full thread engagement through the grip length.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, electricians, or general contractors depending on the application. Power down or de-energize any equipment before fastening components in electrical or mechanical assemblies. Use a properly sized 15/16-inch wrench or socket to avoid rounding the hex.
