Value Collection 313125PR Heavy Hex Nut 9/16-12 Galvanized

Product Description

The VALUE COLLECTION 313125PR is a heavy hex nut designed for use in high-strength structural and industrial bolted connections. Manufactured to ASTM A194 Grade 2H specifications, this nut is built from steel with a galvanized finish that provides corrosion resistance in outdoor and exposed environments. It accepts a 9/16-12 UNC right-hand thread and measures 15/16 inches across the flats with a height of approximately 35/64 inches. The heavier profile compared to a standard hex nut increases bearing surface area and load distribution, making it well suited for high-tension fastener assemblies. Maintenance technicians, ironworkers, pipefitters, and millwrights commonly specify this hardware for structural steel, pressure flange, and heavy equipment applications.

This heavy hex nut is used in industrial, commercial, and infrastructure applications where ASTM A194 Grade 2H fastener hardware is specified. Typical installations include structural steel frameworks, pressure vessel flanges, pipeline assemblies, and mechanical equipment mounting. The galvanized finish makes it appropriate for exterior installations and moderately corrosive environments. It is sold individually with a minimum order quantity of 25 pieces, making it suitable for both job-lot purchasing and maintenance stock replenishment.

Key Features

• ASTM A194 Grade 2H steel construction for high-strength bolting applications
• Galvanized finish provides corrosion resistance for outdoor and exposed-environment use
• 9/16-12 UNC right-hand thread for compatibility with standard inch-series fastener systems
• Heavy hex profile with 15/16 inches across flats increases bearing surface over standard hex nuts
• Height of 35/64 inches provides additional thread engagement depth
• Minimum order quantity of 25 pieces per order

Compatibility

Designed as a standard heavy hex nut for use with 9/16-12 UNC threaded bolts and studs in structural and industrial fastener assemblies requiring ASTM A194 Grade 2H specification hardware.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural or mechanical codes for the assembly type. Always confirm thread engagement depth and torque requirements from the governing engineering specification or fastener standard before installation. De-energize, depressurize, or otherwise make safe any system before working on bolted connections. Do not mix galvanized hardware with incompatible coatings or materials that may cause galvanic corrosion in service.
