Value Collection MSC-72047434 Heavy Hex Nut 3/4-10

Product Description

The VALUE COLLECTION MSC-72047434 is a heavy hex nut manufactured from A194 Grade 2H steel with a zinc yellow dichromate finish. Designed for heavy-duty bolted connections, it features a 3/4-10 UNC right-hand thread and a 1-1/4 inch width across flats. The A194 Grade 2H designation indicates a medium-carbon steel nut heat-treated to meet the mechanical requirements of high-strength structural and pressure applications. The zinc yellow dichromate finish provides corrosion resistance in industrial environments. Trade professionals specify this nut where heavy hex geometry is required by code or engineering specification, particularly in flanged joints, structural steel connections, and pressure vessel assemblies.

This heavy hex nut is suited for commercial, industrial, and infrastructure applications where standard hex nuts do not meet load or code requirements. It is commonly used alongside A193 or A307 heavy hex bolts and threaded rod in structural steel, piping flanges, equipment mounting, and mechanical assemblies. The 3/4-10 UNC thread size is a widely specified fastener dimension across mechanical, HVAC, plumbing, and electrical trade work.

Key Features

• A194 Grade 2H medium-carbon steel construction meets high-strength mechanical requirements
• Zinc yellow dichromate finish provides corrosion resistance for industrial service
• Heavy hex geometry provides greater bearing surface than standard hex nuts
• 3/4-10 UNC right-hand thread for broad compatibility with standard fastener systems
• 1-1/4 inch width across flats for use with standard heavy hex wrenching tooling
• 47/64 inch height suits standard heavy hex nut seating requirements

Compatibility

Designed as an OEM-style replacement or new-installation heavy hex nut for 3/4-10 UNC threaded fastener applications requiring A194 Grade 2H material specification.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional familiar with the applicable bolting standard for the assembly. Shut down and de-energize or depressurize the connected system before servicing any bolted joint. Use a calibrated torque wrench and follow the applicable engineering specification or code requirement for the joint being assembled. Do not reuse nuts that show thread damage, deformation, or corrosion pitting.
