Value Collection R52001253 Square Head Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION R52001253 is a square head bolt designed for general-purpose fastening applications in industrial, mechanical, and structural assemblies. It features a 5/8-11 UNC thread size and a 2-1/4 inch length under head, manufactured from Grade 2 uncoated steel. The square head profile allows positive engagement with a wrench or fitting tool, making it a reliable choice in applications where hex-head access is limited or where the bolt must be held in place while a nut is driven. This fastener conforms to ANSI/ASME B18.2.1 standards and weighs approximately 0.25 pounds.

This bolt is suited for use in light to medium duty structural, mechanical, and general maintenance applications. It is commonly used in wood framing connections, agricultural equipment, conveyor assemblies, and general fabrication where UNC threads and a square-drive head are specified. Trades including millwrights, ironworkers, maintenance mechanics, and general contractors routinely work with this fastener type. Sold individually, it fits applications requiring a single replacement or low-quantity procurement.

Key Features

• 5/8-11 UNC thread for broad compatibility with standard coarse-thread nuts and tapped holes
• 2-1/4 inch length under head suits a range of material stack thicknesses
• Square head profile provides positive wrench engagement in tight or offset installations
• Grade 2 steel construction meets ANSI/ASME B18.2.1 dimensional standards
• Uncoated finish — suitable for dry interior environments or where field coating will be applied

Compatibility

Designed as a standard coarse-thread square head bolt per ANSI/ASME B18.2.1, compatible with any 5/8-11 UNC nut or tapped hole meeting the same standard.

Installation Notes

Install using a properly sized open-end, box, or adjustable wrench rated for the bolt head size. Ensure mating threads are clean and free of debris before assembly. Apply thread lubricant or anti-seize as required by the application environment. Always torque fasteners to values specified in the applicable project drawings or mechanical code — do not estimate torque on structural connections.
