Value Collection HCI20750350G-020BX Hex Head Bolt 3/4-10

Product Description

The VALUE COLLECTION HCI20750350G-020BX is a 3/4-10 hex head bolt designed for general structural and mechanical fastening applications. It features a 3-1/2 inch length under head with partial threading, manufactured from Grade 2 steel and finished with hot-dipped galvanization for corrosion resistance. The bolt conforms to ASTM A307 standards, making it suitable for low-carbon steel structural and mechanical applications. Installation is straightforward with standard hex tooling, and the galvanized finish provides added durability in outdoor or moisture-exposed environments. This fastener is commonly installed by general contractors, millwrights, pipefitters, and maintenance technicians.

This bolt is used across a wide range of commercial and industrial applications including structural steel connections, equipment mounting, pipe supports, and general mechanical assembly. The 3/4-10 UNC thread size is a common inch-series coarse thread designation, compatible with standard 3/4-10 nuts and tapped holes. The partial threading allows for grip-length clamping in bolted joint assemblies where a fully threaded shank is not required. It is equally applicable in residential construction, light commercial work, and maintenance and repair operations.

Key Features

• 3/4-10 UNC coarse thread for compatibility with standard inch-series hardware
• 3-1/2 inch length under head for moderate grip-length fastening
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• Partially threaded shank for clamping force in bolted joint assemblies
• Meets ASTM A307 standard for low-carbon steel hex bolts
• Grade 2 steel construction for general-purpose structural and mechanical use

Compatibility

Designed as an OEM-style replacement and general-use fastener compatible with standard 3/4-10 UNC threaded nuts, washers, and tapped holes in inch-series fastener assemblies.

Installation Notes

Installation requires a standard hex wrench or socket sized for a 3/4-inch hex head bolt. Power down or de-energize any associated equipment before performing fastener work on mechanical or electrical enclosures. Follow applicable structural codes such as AISC or local building standards when using in load-bearing assemblies. Do not substitute this Grade 2 fastener in applications requiring higher-grade bolting such as Grade 5, Grade 8, or ASTM A325 specifications.
