Value Collection HCI20873800G6 Hex Head Bolt 7/8-9 38 in

Product Description

The VALUE COLLECTION HCI20873800G6 is a 7/8-9 UNC hex head bolt designed for heavy structural and industrial fastening applications. Measuring 38 inches under the head, this bolt is partially threaded and manufactured from Grade 2 steel with a hot-dipped galvanized finish for corrosion resistance. It conforms to ASTM A307 standards, making it a recognized option where low-carbon steel anchor bolts or machine bolts are specified. At approximately 1 pound, this fastener is suited for demanding installations that call for a long, full-bodied bolt with a hex drive. Tradespeople working in structural steel, equipment mounting, and general construction will find this part meets common specification requirements.

This bolt is a practical choice in a wide range of commercial and industrial settings, including structural framing, mechanical equipment bases, bridgework, and anchor bolt applications. The partial threading preserves shank strength along the unthreaded portion, which is advantageous when the bolt passes through shear-loaded connections. The hot-dipped galvanized finish suits outdoor and moist-environment use where bare steel would be prone to surface corrosion. Plumbers, HVAC mechanics, electricians, and general contractors will encounter this type of fastener when securing equipment pads, mounting frames, or infrastructure components that require a long, heavy-gauge bolt.

Key Features

• 7/8-9 UNC thread size with partial threading for shear-zone integrity
• 38-inch length under head for deep-reach or through-bolt installations
• Hot-dipped galvanized finish for corrosion resistance in exposed or outdoor environments
• Grade 2 steel construction meeting ASTM A307 fastener standards
• Hex head drive for use with standard wrenches and impact tools

Compatibility

Designed as a standard UNC hex head bolt suitable for structural, mechanical, and construction applications that specify a 7/8-9 thread, 38-inch length, Grade 2 galvanized fastener conforming to ASTM A307.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with applicable structural or mechanical codes. Verify hole clearance and bearing surface condition before installing. Use appropriately rated nuts and washers to match the bolt grade and finish. Always follow the relevant project specifications or engineering drawings for torque and assembly requirements.
