Value Collection HCI41000250N-005BX Hex Head Bolt A490

Product Description

The VALUE COLLECTION HCI41000250N-005BX is a fully threaded hex head bolt manufactured from Grade A490 steel with a bright, uncoated finish. It carries a 1-8 UNC thread size and measures 2-1/2 inches in length under the head. Built to ASTM A490 standards, this bolt is suited for structural and heavy-duty fastening applications where high-strength steel fasteners are specified by code or engineering requirement. It is installed by ironworkers, structural erectors, and mechanical contractors working on steel-to-steel connections that demand certified high-strength hardware.

This bolt is designed for use in structural steel construction and heavy mechanical assemblies where ASTM A490 high-strength fasteners are required. The fully threaded shank provides maximum thread engagement across the entire grip length, making it appropriate for applications with variable material thicknesses or where a nut must be positioned anywhere along the bolt length. Typical installations include steel frame connections, beam-to-column joints, and heavy equipment mounting in commercial and industrial settings.

Key Features

• ASTM A490 certified high-strength steel construction
• 1-8 UNC thread size for standard inch-series nut compatibility
• Fully threaded shank allows flexible nut positioning along the full 2-1/2 inch length under head
• Bright, uncoated finish — suitable for dry or protected environments
• Inch measurement system for use with standard imperial tooling

Compatibility

Designed as a standard ASTM A490 high-strength hex head bolt for use with 1-8 UNC heavy hex nuts and hardened washers in structural steel assemblies conforming to AISC or RCSC bolt specifications.

Installation Notes

Installation of ASTM A490 structural bolts should be performed by qualified ironworkers or structural contractors following RCSC Specification for Structural Joints guidelines. Always verify required installation method — snug-tight, pretensioned, or slip-critical — as specified on the project drawings before installation. Power down or de-energize any adjacent systems before working in confined steel structures. Do not reuse ASTM A490 bolts once fully tensioned, as they are not rated for re-tensioning after initial installation.
