Value Collection HCI30870175N-005BX Hex Head Bolt A325

Product Description

The VALUE COLLECTION HCI30870175N-005BX is a fully threaded hex head bolt designed for structural and general-purpose fastening applications. It features a 7/8-9 UNC thread size with a 1-3/4 inch length under head, manufactured from steel to ASTM A325 specifications. The uncoated bright finish indicates no surface treatment has been applied, making it suitable for use in dry or controlled environments. At 0.836 pounds per unit, this bolt provides the material mass expected from a heavy structural fastener. It is typically installed by ironworkers, structural fabricators, millwrights, and maintenance mechanics working on steel-to-steel connections.

This bolt is suited for structural steel assemblies, equipment mounting, heavy machinery fabrication, and general industrial fastening where ASTM A325 compliance is required. The 7/8-9 thread size and 1-3/4 inch shank length are common in medium-to-heavy structural connections. Full threading along the shank allows engagement across the entire fastened length, which is useful in applications where grip length and thread engagement must be maximized. It is commonly specified in commercial construction, industrial plant maintenance, and equipment manufacturing environments.

Key Features

• 7/8-9 UNC thread provides coarse-thread engagement standard in structural fastening
• Fully threaded shank allows maximum thread engagement for varied grip lengths
• ASTM A325 grade steel meets structural bolt standards for high-strength applications
• Uncoated bright finish suitable for controlled environments or secondary coating application
• 1-3/4 inch length under head fits common medium-depth structural connection details

Compatibility

Designed as an ASTM A325 structural hex head bolt for use in steel-to-steel connections requiring 7/8-9 UNC thread engagement in applications where fully threaded fasteners are specified.

Installation Notes

Installation should be performed by qualified ironworkers, millwrights, or maintenance mechanics following applicable structural codes such as AISC and RCSC specification requirements for high-strength bolts. Torque values and pretension requirements must be determined from project engineering specifications and applicable standards, not from this product listing. Always confirm hole diameter, grip length, and nut compatibility before installation. Do not use impact tools or installation methods that are not approved for ASTM A325 structural bolting assemblies.
