Value Collection HCI30750425NG-005BX Hex Head Bolt 3/8-16

Product Description

The VALUE COLLECTION HCI30750425NG-005BX is a Grade A325 hex head bolt designed for structural and heavy-duty fastening applications. It features a 3/8-16 UNC thread pattern and a length under head of 4.25 inches, with partial threading along the shank. Constructed from steel with a hot-dipped galvanized finish, this bolt provides corrosion resistance in exposed or outdoor environments. It meets ASTM A325 standards, making it appropriate for structural steel connections and high-load assemblies. Licensed tradespeople and contractors working with structural steel, heavy equipment mounting, and fabrication applications will find this bolt suitable for demanding service conditions.

This hex head bolt is used in structural steel construction, equipment mounting, and industrial fabrication where ASTM A325-rated fasteners are required. The hot-dipped galvanized finish makes it a practical choice for exterior installations, bridge components, and other environments where moisture exposure is a factor. Partial threading is typical for structural bolts, allowing the unthreaded shank to bear shear loads in bolted connections. Standard hex drive makes it compatible with common wrenches, impact drivers, and socket sets used in the field.

Key Features

• Grade A325 steel construction meets ASTM A325 structural bolt standards
• 3/8-16 UNC thread pattern for compatibility with standard nuts and tapped holes
• 4.25-inch length under head suits deeper grip ranges in structural assemblies
• Partially threaded shank provides shear resistance in bolted connections
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• Standard hex head drives with common wrenches and impact sockets

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use with standard 3/8-16 UNC hex nuts and structural steel connections in inch-measurement applications.

Installation Notes

Installation should be performed by qualified tradespeople or structural ironworkers following applicable structural codes and project specifications. Verify bolt grade, finish, and thread engagement requirements before installation. Use calibrated torque wrenches when torque values are specified by the engineer of record or applicable standards. Do not mix bolt grades or substitute lower-grade fasteners in ASTM A325-rated connections.
