Value Collection R52001264 Square Head Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION R52001264 is a square head bolt with a 5/8-11 UNC thread size and a 4-1/2 inch length under head. Manufactured from Grade 2 uncoated steel, this bolt meets ANSI/ASME B18.2.1 dimensional standards. The square head design allows for wrench engagement in tight spaces where a hex head may not be practical, and the uncoated finish is suitable for general-purpose structural and mechanical fastening applications. Installers, maintenance technicians, and tradespeople working across construction, HVAC equipment mounting, and mechanical systems commonly use this fastener type.

This bolt is suited for general industrial, construction, and mechanical assembly applications where a UNC-threaded square head fastener is specified. It fits standard 5/8-11 UNC tapped holes and is compatible with corresponding hex nuts and washers of the same thread specification. The Grade 2 steel construction makes it appropriate for low-to-medium strength fastening requirements in non-corrosive indoor or sheltered environments.

Key Features

• 5/8-11 UNC thread for compatibility with standard UNC tapped holes and nuts
• 4-1/2 inch length under head for deeper engagement in structural or mechanical assemblies
• Grade 2 steel construction meets general-purpose strength requirements
• Uncoated finish for standard indoor or sheltered-environment use
• Meets ANSI/ASME B18.2.1 dimensional standards
• Square head profile allows wrench engagement where hex access is limited

Compatibility

Designed as a general-purpose replacement or stock fastener for applications requiring a 5/8-11 UNC square head bolt with a 4-1/2 inch length under head per ANSI/ASME B18.2.1 specifications.

Installation Notes

Installation is performed by mechanical and construction tradespeople using an open-end or adjustable wrench sized to the square head. Power down or de-energize any associated equipment before fastening near electrical components. Do not use this uncoated Grade 2 bolt in outdoor, high-moisture, or corrosive environments without appropriate protective measures. Follow applicable ANSI/ASME and project specifications for torque and assembly requirements.
