Value Collection 7572BMQ Square Head Bolt 3/4-10 Unc

Product Description

The VALUE COLLECTION 7572BMQ is a square head bolt designed for heavy-duty fastening applications in mechanical, structural, and industrial assemblies. It features a 3/4-10 UNC thread with a shank length of 4.5 inches under the head, manufactured from Grade 2 uncoated steel. The square head profile allows for easy gripping with open-end wrenches or pipe wrenches in tight or awkward spaces where hex heads may be difficult to turn. This fastener conforms to ANSI/ASME B18.2.1 dimensional standards. It is used by millwrights, maintenance mechanics, pipefitters, and general tradespeople in a wide range of structural and equipment-mounting situations.

This bolt is suited for general-purpose fastening tasks in commercial and industrial settings, including equipment frames, structural steel connections, pipe supports, and machinery mounting. The 3/4-10 UNC thread is a coarse-thread series, which offers faster engagement and better resistance to cross-threading compared to fine-thread variants. Grade 2 steel provides adequate strength for non-critical structural applications. The uncoated finish means this bolt is intended for dry or controlled environments unless additional corrosion protection is applied at installation.

Key Features

• 3/4-10 UNC coarse thread for fast, reliable engagement
• 4.5 inches length under head for deep-reach fastening applications
• Square head profile for wrench access in confined or irregular mounting scenarios
• Grade 2 steel construction meets general-purpose strength requirements
• Conforms to ANSI/ASME B18.2.1 dimensional standards
• Uncoated finish — suitable for controlled-environment installations

Compatibility

Designed as a standard 3/4-10 UNC square head bolt for general-purpose fastening in structural, mechanical, and industrial assemblies requiring ANSI/ASME B18.2.1 compliant hardware.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or general tradespeople using open-end, box, or pipe wrenches. Ensure mating nut and tapped hole thread specifications match 3/4-10 UNC before installation. Apply thread lubricant or anti-seize compound if the fastener may be exposed to moisture or temperature cycling. Do not exceed the load rating of Grade 2 steel in critical structural applications — consult applicable structural codes for load requirements.
