Value Collection HCI40750400N-005BX Hex Head Bolt 3/4-10

Product Description

The VALUE COLLECTION HCI40750400N-005BX is a 3/4-10 hex head bolt engineered for high-strength structural fastening applications. Manufactured from Grade A490 steel and supplied in a bright, uncoated finish, this bolt meets ASTM A490 standards for heavy structural work where tensile strength requirements exceed those of standard Grade 5 or Grade 8 fasteners. The bolt measures 4 inches in length under head with a 3/4-10 UNC thread pattern and is partially threaded, providing a shank section that is typical in structural connection assemblies. Total weight is approximately 0.83 pounds per unit. Licensed tradespeople working in structural steel erection or heavy equipment installations rely on this class of fastener.

This bolt is suited for structural steel connections in commercial and industrial construction environments where ASTM A490-rated fasteners are specified by engineers or code. The 3/4-10 UNC thread is a standard coarse-thread designation widely called out in structural drawings. Partial threading provides a bearing shank for bolt-grip connections in bolted steel joint assemblies. Installation is typically performed by ironworkers, millwrights, or mechanical contractors working under structural or mechanical codes.

Key Features

• Meets ASTM A490 high-strength structural bolt standard
• 3/4-10 UNC coarse thread for broad tool and nut compatibility
• 4-inch length under head accommodates standard structural grip ranges
• Partially threaded shank reduces thread engagement in the bolt bearing zone
• Bright, uncoated finish — no additional coating treatment to account for in joint slip calculations
• Inch measurement system; compatible with standard imperial hardware

Compatibility

Designed as an OEM-style replacement or direct-use fastener for structural assemblies requiring 3/4-10 UNC hex head bolts rated to ASTM A490.

Installation Notes

Installation of ASTM A490 structural bolts should be performed by qualified tradespeople following AISC and RCSC specifications for structural joints. Torque values, pretension levels, and inspection requirements are governed by project engineering specifications and applicable structural codes — do not assume generic torque values. Ensure mating nuts and washers meet the corresponding ASTM specification requirements called out in the connection design. Confirm bolt grip length and thread engagement before final installation.
