Value Collection HCI20750900G6-001BX Hex Head Bolt 3/4-10 9 in

Product Description

The VALUE COLLECTION HCI20750900G6-001BX is a 3/4-10 UNC hex head bolt with a 9-inch length under head, manufactured from Grade 2 steel with a hot-dipped galvanized finish. It is partially threaded and meets ASTM A307 standards, making it a general-purpose structural fastener suited for medium-duty bolted connections. Electricians, plumbers, HVAC technicians, and general contractors reach for this bolt when assembling equipment supports, pipe hangers, equipment pads, and structural frames where corrosion resistance is needed. The hot-dipped galvanized coating provides a robust zinc layer that holds up in damp or outdoor environments better than electroplated alternatives.

This bolt is used across residential and light commercial construction and mechanical trades. Common applications include securing equipment mounting pads, attaching pipe support strut, bolting conduit hangers to structural steel, and assembling outdoor or underground-adjacent assemblies where moisture exposure is a concern. The 9-inch shank length suits through-bolting of thicker assemblies such as stacked lumber, double-channel strut, or concrete anchor setups. Grade 2 steel is appropriate for general structural connections that do not require the higher proof load of Grade 5 or Grade 8 fasteners.

Key Features

• 3/4-10 UNC thread size for standard inch-series nuts and hardware
• 9-inch length under head accommodates through-bolting of thick assemblies
• Hot-dipped galvanized finish provides heavy zinc coating for corrosion resistance in wet or outdoor environments
• Partially threaded shank allows the unthreaded portion to bear shear loads in bolted connections
• Meets ASTM A307 standard for general-purpose low-carbon steel bolts
• Grade 2 steel suitable for non-critical structural and mechanical fastening applications

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts, flat washers, and lock washers in inch-series fastener assemblies across mechanical, electrical, and structural trade applications.

Installation Notes

Install using a standard 1-1/8-inch hex wrench or impact socket. Apply flat washers under the head and nut to distribute clamping load across the connected material. Hot-dipped galvanized fasteners should not be mixed with stainless steel hardware in direct contact, as galvanic corrosion can occur. Torque to the connection design specification per applicable structural or mechanical drawings; no specific torque value is provided for this fastener in the available product data.
