Value Collection HCI31000350N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI31000350N-005BX is a 1-8 UNC hex head bolt designed for structural and heavy-duty fastening applications. Manufactured from A325-grade steel with a bright uncoated finish, this bolt measures 3-1/2 inches in length under the head and features partial threading along the shank. It meets ASTM A325 standards, making it appropriate for high-strength structural connections. Weighing approximately 1 pound per unit, it is a reliable choice for steel-to-steel connections in commercial and industrial construction. Installation is typically performed by ironworkers, structural mechanics, and general contractors working to applicable structural codes.

This hex head bolt is suited for structural steel assemblies, heavy equipment mounting, and load-bearing fastener applications where ASTM A325 compliance is required. The partially threaded shank provides a smooth bearing surface through the grip length, which is preferred in shear-critical connections. It is sold individually and is applicable in both new construction and retrofit structural work requiring certified high-strength fasteners.

Key Features

• 1-8 UNC thread size for broad compatibility with standard structural hardware
• 3-1/2 inch length under head for appropriate grip in typical structural steel connections
• Grade A325 steel construction meeting ASTM A325 fastener standards
• Partially threaded shank provides a smooth shank bearing surface through the grip zone
• Bright uncoated finish suitable for indoor structural applications or where field coating is applied

Compatibility

Designed as an ASTM A325-compliant high-strength hex head bolt for use in standard structural steel connections requiring 1-8 UNC threading and 3-1/2 inch under-head length.

Installation Notes

Installation should be performed by qualified ironworkers or structural mechanics following AISC and applicable structural bolt installation standards. Snug-tighten and pretensioning procedures should comply with the RCSC Specification for Structural Joints. Always confirm hole clearance, washer requirements, and nut grade compatibility before installation. Do not use impact tools that exceed the torque capacity appropriate for the connection design.
