Value Collection HCI30870375N-005BX Hex Head Bolt 7/8-9

Product Description

The VALUE COLLECTION HCI30870375N-005BX is a heavy hex head bolt engineered for structural fastening applications. This bolt features a 7/8-9 thread size with Unified National Coarse (UNC) thread form and measures 3.75 inches in length under the head. It is manufactured from steel to ASTM A325 structural bolt standards, making it appropriate for high-strength bolted connections in steel-to-steel assemblies. The uncoated, bright finish indicates no additional corrosion treatment has been applied. Partial threading is standard for this configuration, leaving a shank section below the head for load-bearing fit in clearance holes. Installation is performed by licensed ironworkers, structural mechanics, or qualified maintenance tradespeople.

This bolt is suited for structural steel construction, heavy equipment assembly, and industrial maintenance applications requiring ASTM A325 compliance. Typical installations include beam-to-column connections, base plate anchor assemblies, and bolted structural joints where high-strength fasteners are specified by an engineer of record. The inch measurement system and UNC thread form are standard in domestic structural fabrication and field erection work.

Key Features

• ASTM A325 structural bolt standard for high-strength bolted steel connections
• 7/8-9 UNC thread form for compatibility with standard structural hardware
• 3.75-inch length under head accommodates standard connection stack-ups
• Partially threaded shank maintains full bearing surface in clearance holes
• Bright uncoated finish — no coating interference with slip-critical faying surfaces
• Steel construction rated to A325 material grade requirements

Compatibility

Designed as an ASTM A325 structural hex head bolt for use with standard 7/8-inch heavy hex nuts and hardened washers in structural steel bolting assemblies. No specific model or system compatibility was provided in the product data.

Installation Notes

Installation of A325 structural bolts should be performed by qualified ironworkers or structural mechanics in accordance with AISC and RCSC specification requirements for structural joints using high-strength bolts. Always confirm the required installation method — snug-tight, pretensioned, or slip-critical — as specified in the structural drawings before proceeding. Power down or de-energize any adjacent electrical equipment before working in proximity to energized panels or conduit. Do not substitute standard hex bolts for A325-specified connections without engineering approval.
