Value Collection R52001261 Square Head Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION R52001261 is a square head bolt designed for general fastening applications in mechanical, structural, and industrial assemblies. It features a 5/8-11 UNC thread standard and a 3-1/4 inch length under head. Constructed from Grade 2 steel with an uncoated finish, this bolt is suited for use in non-corrosive environments where standard carbon steel fastener strength meets application requirements. Square head bolts are commonly installed by maintenance technicians, pipefitters, millwrights, and general contractors working on equipment mounting, pipe support, or structural connections.

This fastener is appropriate for residential and light commercial applications where UNC coarse thread engagement is required. The square head profile allows installation and removal with a wrench or adjustable tool in confined spaces where a hex head may not seat properly. It is sold as a single-piece unit and is well suited for replacement fastening, fabrication work, or MRO inventory.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 3-1/4 inch length under head provides adequate thread engagement for medium-thickness structural connections
• Grade 2 steel construction meets standard tensile requirements for general-purpose fastening
• Uncoated finish suitable for dry or protected indoor installations
• Square head profile allows wrench engagement in tight or recessed installation areas

Compatibility

Designed as a general-purpose replacement or OEM-style fastener for any application requiring a 5/8-11 UNC square head bolt with a 3-1/4 inch length under head in Grade 2 uncoated steel.

Installation Notes

Installation should be performed by a qualified technician or tradesperson using appropriate hand or power tools. Ensure mating threads and tapped holes are clean and free of debris before installation. Do not exceed the rated load capacity of Grade 2 fasteners in high-stress or shear-critical applications. Torque to the appropriate specification for the joint material and bolt diameter as defined by applicable codes or engineering requirements.
