Value Collection 75160BMQ Square Head Bolt 3/4-10 Unc

Product Description

The VALUE COLLECTION 75160BMQ is a square head bolt designed for heavy fastening applications in structural, mechanical, and industrial assembly work. Featuring a 3/4-10 UNC thread size and 10 inches of length under the head, this bolt provides a large bearing surface that resists loosening under torque and allows for positive wrench engagement with a pipe wrench or box-end wrench. Manufactured from Grade 2 steel with no coating, it is suited for general-purpose indoor and sheltered fastening where corrosion resistance is not a primary requirement. Installation is typically handled by millwrights, ironworkers, pipefitters, and general contractors.

Square head bolts in this size range are commonly used in timber framing, heavy equipment mounting, conveyor systems, and structural steel connections where conventional hex head access may be limited or where high wrench torque is needed. The 3/4-10 UNC thread pitch is a coarse-thread standard, making assembly and disassembly straightforward even in field conditions where fine threads would be prone to cross-threading or contamination. This bolt ships as a single-piece quantity.

Key Features

• 3/4-10 UNC coarse thread for reliable engagement in field assembly conditions
• 10 inches length under head accommodates deep stack fastening and thick material passes
• Square head profile allows pipe wrench or open-end wrench torque in tight or awkward spaces
• Grade 2 steel construction meets general-purpose structural fastening requirements
• Uncoated finish — suitable for dry or sheltered environments
• Manufactured to ANSI/ASME B18.2.1 dimensional standards

Compatibility

Designed as a general-purpose replacement or new-installation square head bolt for applications requiring a 3/4-10 UNC coarse thread and 10-inch under-head length per ANSI/ASME B18.2.1 specifications.

Installation Notes

Installation is performed by qualified tradespeople using appropriate wrenches or impact tooling rated for 3/4-inch fasteners. Always use a hardened flat washer and appropriately rated nut to match the Grade 2 rating of this bolt. De-energize, depressurize, or otherwise make safe any equipment before fastening into or adjacent to mechanical or electrical systems. Do not use this uncoated bolt in continuously wet, submerged, or corrosive environments without additional protective measures.
