Value Collection HCI30620375NG-010BX Hex Head Bolt Grade A325

Product Description

The VALUE COLLECTION HCI30620375NG-010BX is a 5/8-11 UNC hex head bolt designed for structural and heavy-duty mechanical fastening applications. It is manufactured from A325 steel with a hot-dipped galvanized finish that provides corrosion resistance in outdoor and exposed environments. The bolt measures 3-3/4 inches in length under the head and features partial threading, which is standard for structural bolting where the shank must bear shear loads across a joint interface. Weighing 0.261 pounds, this fastener meets ASTM A325 specifications for medium-carbon steel structural bolts. It is installed using standard hex wrenches or impact drivers and is suited for use in steel-to-steel connections, beam splices, and bracket assemblies.

This bolt is commonly used in structural steel construction, heavy equipment fabrication, and industrial maintenance applications. The 5/8-11 thread size and 3-3/4 inch length under head make it a practical choice for connecting steel members where ASTM A325 compliance is required by specification or code. The hot-dipped galvanized finish makes it appropriate for exterior and corrosive-environment installations where plain steel would be unsuitable. Ironworkers, millwrights, and construction crews working to AISC or project-specific structural standards will find this bolt well suited to high-load connection points.

Key Features

• 5/8-11 UNC thread size with partial threading for shear-load bearing applications
• ASTM A325 certified medium-carbon structural steel construction
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• 3-3/4 inch length under head for deep structural connections
• Inch measurement system, standard hex head drive

Compatibility

Designed as a standard ASTM A325 structural hex head bolt for use in steel-to-steel connections where 5/8-11 UNC thread size and a 3-3/4 inch grip range are required by design specification.

Installation Notes

Installation of A325 structural bolts should be performed by qualified ironworkers or structural trades personnel following applicable AISC and RCSC specification requirements. Bolts should be installed using calibrated torque wrenches or tension-control methods as required by the connection design. Do not reuse structural bolts once fully tensioned, as proof-load capacity may be compromised. Ensure mating surfaces are clean and free of scale, paint, or debris before assembly.
