Value Collection HCI21001800G6-001BX Hex Head Bolt 18in Grade 2

Product Description

The VALUE COLLECTION HCI21001800G6-001BX is a Grade 2 steel hex head bolt with a 1-8 UNC thread and an 18-inch length measured under the head. The bolt is partially threaded and finished with a hot-dipped galvanized coating for corrosion resistance in outdoor and high-moisture environments. It meets ASTM A307 standards, making it appropriate for general structural and mechanical fastening applications where a low-carbon steel fastener with controlled tensile strength is required. Weighing approximately 1 pound, this fastener is suited for heavy assemblies that demand a long-reach bolt with reliable thread engagement.

This bolt is commonly used in construction, infrastructure, HVAC equipment mounting, plumbing support structures, and general industrial assembly. It is well suited for connecting heavy timber, steel framing, equipment bases, and structural brackets where a 1-inch diameter, partially threaded fastener with a standard hex head is specified. The hot-dipped galvanized finish makes it appropriate for exterior installations or environments with elevated moisture exposure. Tradespeople including pipefitters, structural ironworkers, HVAC installers, and general contractors regularly use this size in large-scale fastening applications.

Key Features

• 1-8 UNC thread form — standard coarse thread for general structural use
• 18-inch length under head provides extended reach for thick material assemblies
• Grade 2 low-carbon steel construction meets ASTM A307 tensile requirements
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor or wet conditions
• Partially threaded shank allows for a stronger bearing surface in wood and structural connections
• Hex head design accepts standard wrenches and impact sockets

Compatibility

Designed as a general-purpose Grade 2 hex head bolt for structural and mechanical fastening applications requiring a 1-8 UNC thread, 18-inch length, and hot-dipped galvanized finish per ASTM A307.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with applicable structural fastening standards and torque requirements for the specific assembly. Always verify that the receiving material and nut specification match the Grade 2 ASTM A307 rating before installation. Use appropriate wrenches or impact tools rated for 1-inch fasteners. Do not exceed the rated tensile load for this grade when specifying in load-bearing connections.
