Value Collection HCI31120650NG-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120650NG-005BX is a heavy-duty hex head bolt engineered for structural steel connections and high-load fastening applications. It features a 1-1/8-7 UNC thread size with a 6.5-inch length under the head and a partially threaded shank. The bolt is manufactured from steel to ASTM A325 specifications and finished with a hot-dipped galvanized coating for corrosion resistance in exposed or outdoor environments. Ironworkers, structural steel erectors, and licensed contractors install this fastener in demanding load-bearing assemblies where grade and certification matter.

This bolt is suited for structural steel fabrication, steel-to-steel connections, bridge construction, heavy equipment mounting, and similar high-strength applications governed by AISC and RCSC specifications. The ASTM A325 grade designation makes it appropriate for use in slip-critical and bearing-type structural connections. The hot-dipped galvanized finish extends service life in exterior or high-humidity environments. Sold individually, it is also available in box quantities for larger project needs.

Key Features

• 1-1/8-7 UNC thread form for compatibility with standard heavy structural hardware
• 6.5-inch length under head accommodates thick material stack-ups
• Partially threaded shank provides a bearing surface through the grip length
• ASTM A325 certified for structural steel applications
• Hot-dipped galvanized finish delivers corrosion resistance in exterior conditions
• Inch measurement system; thread standard UNC

Compatibility

Designed as an ASTM A325 structural hex bolt for use with standard heavy hex nuts and hardened washers in steel-to-steel structural connections per applicable AISC and RCSC guidelines.

Installation Notes

Installation should be performed by qualified ironworkers or structural contractors following RCSC Specification for Structural Joints requirements. Shut down or de-energize adjacent systems before working in close proximity to electrical infrastructure. Use calibrated torque wrenches or tension-control tools as required by the applicable structural specification. Do not reuse galvanized structural bolts that have been fully tensioned.
