Value Collection R52001259 Square Head Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION R52001259 is a square head bolt designed for general fastening applications where a wrench-driven, non-round head profile is required. It features a 5/8-11 UNC thread size and a 3-inch length under head, giving it solid grip depth for medium-duty structural and mechanical connections. The bolt is manufactured from Grade 2 steel with no coating, making it a straightforward, cost-effective choice for indoor or sheltered assemblies. It meets ANSI/ASME B18.2.1 standards, which ensures dimensional consistency across procurement and installation. Plumbers, HVAC technicians, pipefitters, and general contractors commonly use square head bolts when working with hangers, brackets, and utility framework.

This bolt is suited for residential and light commercial applications where a square head profile is specified or preferred for wrenching access. The uncoated steel construction is appropriate for dry or protected environments. It is typically used in mechanical rooms, equipment mounting, structural brackets, and utility connections where Grade 2 steel strength meets load requirements. The 5/8-11 UNC thread is a common coarse-thread specification, compatible with standard UNC nuts and tapped holes of the same designation. Sold individually, it fits low-quantity replacement and repair needs.

Compatibility

Designed as a standard UNC square head bolt compatible with 5/8-11 UNC nuts and tapped holes conforming to ANSI/ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriate open-end or adjustable wrench sized for the square head profile. Ensure the mating nut or tapped hole is the same thread specification (5/8-11 UNC) before installation to avoid cross-threading. Always verify that Grade 2 steel meets the load and shear requirements of the application before use in structural connections. Do not use in high-moisture or corrosive environments without additional protection, as the bolt is uncoated steel.
