Value Collection HCI31000550N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000550N-005BX is a heavy-duty hex head bolt designed for structural and industrial fastening applications. Built to ASTM A325 specifications, this bolt is manufactured from steel with a bright, uncoated finish. It features a 1-8 UNC thread size with a 5-1/2 inch length measured under the head, and is partially threaded to suit through-bolt and structural connection applications. Weighing approximately 1 pound, it is suited for single-piece procurement by contractors, fabricators, and maintenance technicians who require a reliable A325-grade structural fastener in standard inch dimensions.

This bolt is commonly used in structural steel connections, heavy equipment assembly, and industrial fabrication where ASTM A325 compliance is required. The partial threading provides a smooth shank section ideal for load-bearing shear connections. Typical installation scenarios include beam-to-column connections, equipment mounting, and bridge or building framework assembly where high-strength fasteners are specified by design engineers or required by code.

Key Features

• ASTM A325 compliant construction for structural fastening requirements
• 1-8 UNC thread size with partial threading for shear-critical connections
• 5-1/2 inch length under head in standard inch measurement
• Bright, uncoated steel finish for straightforward installation without coating interference
• Heavy-duty steel material rated to Grade A325 material specification

Compatibility

Designed as an OEM-style replacement or standard structural fastener for applications requiring 1-8 UNC hex head bolts meeting ASTM A325 specifications in inch-system assemblies.

Installation Notes

Installation should be performed by qualified structural ironworkers, millwrights, or maintenance technicians familiar with AISC and RCSC bolt installation standards. Always de-energize or relieve loads from the connection point before servicing existing hardware. Use calibrated torque wrenches or approved turn-of-nut methods when tightening A325 structural bolts to specification. Do not modify, re-use as a tension-control bolt, or substitute for a different grade without engineering approval.
