Value Collection HCI20620225G-025BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI20620225G-025BX is a 5/8-11 hex head bolt with a 2-1/4-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 suitable for general structural and mechanical fastening applications. The hot-dipped galvanized coating provides corrosion resistance for use in exposed or moisture-prone environments. Licensed tradespeople and contractors working in construction, mechanical systems, and equipment installation regularly use this bolt type where a standard-strength, corrosion-resistant fastener is required.

This bolt is used across a range of commercial and residential construction applications including structural connections, equipment mounting, and general mechanical assembly. The 5/8-11 UNC thread size is a common inch-standard fastener used in steel framing, HVAC equipment bases, plumbing supports, and electrical enclosure mounting. Partial threading allows for greater shank strength and grip in thicker material assemblies. The ASTM A307 rating indicates compliance with standard specifications for carbon steel bolts used in structural and pressure-containing applications.

Key Features

• 5/8-11 UNC thread size with 2-1/4-inch length under head
• Hot-dipped galvanized finish for corrosion resistance in wet or outdoor environments
• Partially threaded shank for increased grip and shear strength in thick material joints
• Grade 2 steel construction meets ASTM A307 standard specifications
• Inch system of measurement — compatible with standard UNC tooling and hardware

Compatibility

Designed as a standard-replacement hex head bolt for general structural, mechanical, and equipment fastening applications requiring a 5/8-11 UNC partially threaded bolt with a galvanized finish.

Installation Notes

Installation is typically performed by electricians, HVAC technicians, plumbers, or general contractors depending on the application. Use the appropriate 15/16-inch hex wrench or socket for driving. Ensure mating threads and hardware are clean and free of debris before assembly. Do not mix galvanized fasteners with dissimilar metals in highly corrosive environments without appropriate isolation to prevent galvanic corrosion.
