Value Collection 747248BR Square Head Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION 747248BR is a square head bolt designed for general fastening applications in structural, mechanical, and industrial assemblies. It features a 5/8-11 UNC thread profile with 3-1/2 inches of length under the head, providing solid clamping force in through-bolted connections. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI/ASME B18.2.1 standards. The square head design allows engagement with pipe wrenches, open-end wrenches, and socket tools where a hex head may not be accessible or appropriate. Licensed tradespeople working in mechanical, structural, and HVAC support applications will find this bolt suited to everyday fastening tasks.

This square head bolt is used in residential and commercial construction, mechanical equipment mounting, structural framing, and utility installations where UNC fasteners are specified. Its uncoated Grade 2 steel construction makes it appropriate for interior or protected environments. The 5/8-11 thread size is commonly encountered in equipment anchoring, pipe support brackets, and similar trade applications where coarse-thread fasteners are standard practice.

Installation Notes

Installation is typically performed by licensed mechanical, structural, or HVAC technicians following applicable building and mechanical codes. Always de-energize and isolate any equipment before installing or removing fasteners on live assemblies. Use an appropriately sized open-end wrench, pipe wrench, or socket to torque the bolt evenly — avoid over-tightening, which can strip Grade 2 threads. Uncoated steel fasteners should not be used in wet, corrosive, or exterior environments without appropriate protective measures.
