Value Collection HCI31000800N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000800N-005BX is a heavy-duty hex head bolt designed for structural and industrial fastening applications. Manufactured from steel to ASTM A325 specifications, this bolt features a 1-8 UNC thread size with 8 inches of length measured under the head. The partial threading configuration is standard for structural connections, leaving a shank section that resists shear loads in bolted assemblies. The bright, uncoated finish means this bolt ships without any surface treatment, making it suitable for applications where coating would interfere with friction-critical connections or where field-applied coatings are specified.

This bolt is used in structural steel construction, heavy equipment assembly, and industrial fabrication where ASTM A325 fastener standards are required by design specification or engineering mandate. Typical installations include steel-to-steel bolted connections in commercial and industrial building frames, bridges, and machinery bases. The 1-8 UNC thread series and 8-inch grip length make this a large-diameter fastener suited for thick or multi-layer structural stack-ups.

Key Features

• ASTM A325 structural bolt standard for high-strength applications
• 1-8 UNC thread size for compatibility with standard heavy structural hardware
• 8 inches length under head accommodates thick structural members
• Partially threaded shank provides shear resistance at the connection interface
• Bright uncoated finish — no coating to compromise friction-critical or field-coated joints
• Steel construction with A325 material grade for proven structural integrity

Compatibility

Designed as an ASTM A325 structural hex head bolt for use with standard heavy hex nuts and hardened washers in bolted structural steel connections per applicable engineering specifications.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural trades familiar with AISC and RCSC bolt installation specifications. Tighten using calibrated torque wrenches, tension-indicating washers, or turn-of-nut methods as required by the project specification — do not estimate torque by feel. Inspect thread engagement and bearing surface condition before torquing. Follow applicable OSHA and project safety requirements when working on structural steel.
