Value Collection HCI30620300NG-010BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI30620300NG-010BX is a 5/8-11 hex head bolt manufactured from Grade A325 steel with a hot-dipped galvanized finish. It measures 3 inches in length under the head and features partial threading along the shank. The bolt conforms to ASTM A325 structural fastener standards, making it suited for steel-to-steel connection work in construction and industrial applications. Weighing 0.23 pounds, it uses a unified coarse (UNC) thread standard. Licensed trades including ironworkers, structural steel contractors, and industrial maintenance mechanics typically specify this fastener for bolted joint assemblies requiring documented material certification.

This bolt is designed for structural and heavy-duty mechanical applications where ASTM A325 certification is required by specification. The hot-dipped galvanized coating provides corrosion resistance suitable for exterior or moderately corrosive environments. Partial threading is standard for structural connection applications where the shank bears shear load across the joint interface. Typical install scenarios include steel frame connections, equipment mounting to structural steel, and heavy fabrication work governed by AISC or similar structural codes.

Key Features

• Grade A325 steel meets ASTM A325 structural fastener certification requirements
• Hot-dipped galvanized finish provides corrosion resistance for exterior and industrial use
• Partially threaded shank suitable for shear-loaded structural connections
• 5/8-11 UNC thread for compatibility with standard structural nuts and washers
• 3-inch length under head accommodates typical structural steel joint stack-ups

Compatibility

Designed as an ASTM A325-compliant structural hex bolt for use with standard 5/8-11 UNC heavy hex nuts and hardened washers in steel-to-steel bolted connections.

Installation Notes

Installation should be performed by qualified personnel following applicable structural codes such as AISC or RCSC bolt specification requirements. Always power down or de-energize adjacent systems and follow site lock-out procedures before working in live structural or equipment areas. Use calibrated torque wrenches or an approved turn-of-nut method as required by the governing specification. Do not substitute standard hex nuts for heavy hex nuts where the connection specification requires them.
