Value Collection HCI30750350N-010BX Hex Head Bolt 3/4-10

Product Description

The VALUE COLLECTION HCI30750350N-010BX is a 3/4-10 hex head bolt designed for structural and heavy-duty fastening applications. This bolt measures 3.5 inches in length under the head, features a partially threaded shank, and is manufactured from steel to ASTM A325 structural bolt standards. The uncoated, bright finish leaves the steel in its natural state with no additional surface treatment. Partially threaded shank geometry concentrates grip load in the unthreaded body, making it well suited for high-strength bolted connections in steel construction and fabrication work.

This bolt is used in structural steel connections, steel-to-steel clamping applications, and general industrial fastening where ASTM A325 material grade is specified by an engineer or code requirement. It is a common choice in building frames, bridges, heavy equipment assemblies, and other load-bearing connections. Installation typically falls to ironworkers, structural contractors, millwrights, or maintenance mechanics working to design specifications that call out A325 bolting.

Key Features

• 3/4-10 thread size with UNC (Unified National Coarse) thread standard
• 3.5 inch length measured under the head
• Partially threaded shank for full bearing load transfer in structural joints
• ASTM A325 material grade — meets structural bolt specification for high-strength steel connections
• Bright/uncoated finish — no coating added, suitable for applications where surface treatment is specified separately or not required
• Inch measurement system; sold individually

Compatibility

Designed as an ASTM A325-compliant structural hex head bolt for use in bolted steel connections where 3/4-10 UNC thread and 3.5 inch under-head length are specified.

Installation Notes

Installation should be performed by qualified ironworkers or structural mechanics following the applicable design drawings and specifications. Consult the AISC or project engineer specifications for required pretension values, installation method (turn-of-nut, tension control, or direct tension indicator), and inspection requirements. Always use appropriate matched nuts and hardened washers as specified. Do not modify, weld, or heat-treat the bolt after installation.
