Value Collection 75192BMQ Square Head Bolt 3/4-10 Unc

Product Description

The VALUE COLLECTION 75192BMQ is a square head bolt designed for heavy-duty fastening applications in industrial, mechanical, and construction settings. It features a 3/4-10 UNC thread with a 12-inch length under head, manufactured from Grade 2 steel in an uncoated finish. The square head profile provides secure wrench or pipe-wrench engagement, making it well suited for applications where standard hex heads may slip or where a positive grip is required. Licensed tradespeople and experienced installers working in structural assemblies, machinery mounting, and similar applications are the primary users of this fastener.

This bolt is commonly used in fabrication, agricultural equipment, general mechanical assembly, and structural installations where UNC thread engagement and a full 12-inch under-head length are required. The uncoated Grade 2 steel construction is appropriate for interior or protected environments where corrosion exposure is limited. It conforms to ANSI/ASME B18.2.1 dimensional standards, ensuring consistent fitment with standard UNC nuts and threaded components.

Key Features

• 3/4-10 UNC thread for compatibility with standard unified coarse-thread fastener systems
• 12-inch length under head suits deep-reach and through-bolting applications
• Square head design allows positive wrench engagement in confined or high-torque situations
• Grade 2 steel construction meets ANSI/ASME B18.2.1 dimensional standards
• Uncoated finish suitable for dry or protected installation environments

Compatibility

Designed for use with standard 3/4-10 UNC nuts and threaded components conforming to ANSI/ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with proper fastener torque practices for Grade 2 steel bolts. Always use a correctly sized square-head wrench or pipe wrench to avoid rounding the head during installation. Ensure mating nut or threaded hole is clean, undamaged, and correctly sized for 3/4-10 UNC thread engagement before driving the bolt. Do not exceed the rated load capacity for Grade 2 steel fasteners in structural or load-bearing assemblies.
