Value Collection HCI31250800N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31250800N-005BX is a heavy-duty hex head bolt engineered for structural and industrial fastening applications. It features a 1-1/4-7 UNC thread size with 8 inches of length measured under the head. Constructed from steel to ASTM A325 specifications, this bolt is partially threaded and carries a bright uncoated finish. It is a common choice for steel-to-steel structural connections where high-strength fasteners are required by code or project specification.

This bolt is used in structural steel construction, heavy equipment assembly, and industrial fabrication where ASTM A325 high-strength fasteners are specified. The partial threading is standard for grip-length-critical connections where a full shank is required through the joint material. Contractors, ironworkers, and maintenance professionals working on steel structures, bridges, and heavy machinery frames regularly specify this grade and size.

Key Features

• 1-1/4-7 UNC thread conforms to inch-series thread standards
• 8-inch length under head accommodates substantial material stack-up
• ASTM A325 structural steel grade meets high-strength bolt specifications
• Partial threading provides a full shank section for shear-critical joints
• Bright uncoated finish suitable for dry indoor structural applications or where field coating will be applied
• Sold individually — no minimum order beyond a single piece

Compatibility

Designed as a standard ASTM A325 structural hex bolt for use in steel-to-steel connections where inch-series high-strength fasteners are specified; confirm thread engagement, grip length, and load requirements against project drawings before installation.

Installation Notes

Installation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural trades familiar with the AISC and RCSC Specification for Structural Joints. Fastener assemblies must be tightened using calibrated torque wrenches, tension-control methods, or direct-tension indicators as specified by the project engineer. Never reuse A325 bolts that have been fully tensioned. Verify nut and washer compatibility with the selected tightening method before beginning installation.
