Value Collection HCI31120700N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31120700N-005BX is a heavy-duty hex head bolt manufactured from steel to ASTM A325 structural standards. It features a 1-1/8-7 UNC thread size with a 7-inch length measured under the head and a partially threaded shank. The bright, uncoated finish indicates bare steel with no surface treatment applied. This bolt is built for high-strength structural connections where load-bearing integrity is the primary requirement. It weighs approximately 1 pound. Installation is performed by ironworkers, structural mechanics, and licensed contractors working on steel-to-steel or steel-to-concrete connections requiring verified tensile strength.

This bolt is suited for structural steel framing applications in both commercial and industrial construction environments. Typical use cases include beam-to-column connections, steel moment frames, and bolted splice plates where ASTM A325 compliance is specified by the engineer of record. The partially threaded shank provides a smooth bearing surface through the grip length, which is a common requirement in shear-critical joints. A single bolt is included per package.

Key Features

• ASTM A325 rated for high-strength structural bolting applications
• 1-1/8-7 UNC thread size for compatibility with standard structural hardware
• 7-inch length under head for deep grip applications
• Partially threaded shank provides a full bearing surface through the grip zone
• Bright, uncoated steel finish — no coating to account for in joint design
• Inch measurement system; conforms to ASTM A325 fastener standard

Compatibility

Designed as an ASTM A325 compliant structural hex head bolt suitable for high-strength bolted connections in steel construction where a 1-1/8-7 UNC thread pattern and 7-inch grip length are specified.

Installation Notes

Installation should be performed by qualified ironworkers or structural contractors following AISC and RCSC specifications for structural bolting. Use calibrated torque wrenches or tension-control tools appropriate for the joint type; do not estimate final tension by feel. Ensure mating nuts and washers conform to the same ASTM standards called out in the project drawings. Inspect threads for damage before installation and do not use bolts with nicked or cross-threaded shanks.
