Value Collection R52001257 Square Head Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION R52001257 is a square head bolt designed for general fastening applications where a wrench-gripping profile is required. It features a 5/8-11 UNC thread size and a 2-3/4 inch length under head, machined from Grade 2 steel with an uncoated finish. The square head design allows for positive wrench engagement in tight clearance situations where a hex head may slip or be difficult to access. This bolt meets ANSI/ASME B18.2.1 dimensional standards and is suited for structural and mechanical assembly work performed by millwrights, maintenance technicians, and general tradespeople.

This bolt is a practical choice for light-to-medium duty structural connections, machinery mounting, equipment frames, and utility installations. The 5/8-11 UNC coarse thread pitch provides reliable engagement in steel, cast iron, and similar materials. The uncoated finish makes it appropriate for dry or protected indoor environments. Single-unit packaging allows for exact-quantity procurement without overstock, useful for service and repair scenarios where a single replacement fastener is needed.

Key Features

• 5/8-11 UNC coarse thread for reliable engagement in standard tapped holes and nuts
• 2-3/4 inch length under head for moderate grip range in structural and mechanical assemblies
• Square head profile allows positive wrench engagement in confined spaces
• Grade 2 steel construction provides adequate tensile strength for light-to-medium duty loads
• Uncoated finish suitable for dry, protected indoor environments
• Meets ANSI/ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard UNC fastener compatible with any 5/8-11 threaded nut or tapped hole conforming to ANSI/ASME dimensional standards for coarse-thread series fasteners.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or general tradespeople using a standard open-end, box-end, or adjustable wrench sized for a square head profile. Inspect the mating threads and tapped hole for damage or contamination before installation. Do not exceed the load rating of a Grade 2 fastener in high-stress or shear-critical applications. Follow applicable structural or mechanical codes for torque requirements relevant to the specific assembly.
