Value Collection -36658-B Hex Nut 3/4-10 Grade 2H

Product Description

The VALUE COLLECTION -36658-B is a 3/4-10 hex nut rated to ASTM Grade 2H, designed for heavy hex bolting applications where higher proof load strength is required compared to standard Grade 2 fasteners. Grade 2H nuts are commonly specified in structural and pressure vessel bolting, meeting ASTM A194 requirements for heavy-duty mechanical and industrial assemblies. This nut is installed by millwrights, pipefitters, structural ironworkers, and maintenance technicians working on equipment requiring reliable, high-load fastening.

This hex nut is suited for general industrial, structural, and mechanical applications using 3/4-10 UNC threaded fasteners. It is commonly used in flanged connections, equipment frames, structural steel assemblies, and piping supports where Grade 2H proof load ratings are specified by engineering or code requirements.

Key Features

• 3/4-10 UNC thread size for use with standard 3/4-inch coarse-thread bolts and studs
• Grade 2H rating provides higher proof load capacity than standard Grade 2 fasteners
• Hex drive for use with standard wrenches and impact tools
• Sold individually with a minimum order quantity of 100 pieces

Compatibility

Designed as an OEM-style replacement or new-installation fastener for 3/4-10 UNC threaded bolts and studs in industrial, structural, and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable codes such as AISC, ASME, or facility-specific torque specifications. Always ensure mating threads are clean and free of debris before assembly. Power down or de-energize any associated equipment before performing fastener work in live mechanical systems. Do not exceed the rated proof load of the nut for the given bolt grade and application.
