Value Collection -36657-B Hex Nut 5/8-11 Grade 2H

Product Description

The VALUE COLLECTION -36657-B is a heavy hex nut in a 5/8-11 thread size, manufactured to Grade 2H specifications. Grade 2H heavy hex nuts are engineered for high-strength bolting applications where elevated proof load and hardness are required. This nut is commonly used in structural and industrial fastener assemblies, including pipe flange connections, heavy equipment mounting, and structural steel applications. Licensed tradespeople and maintenance professionals in plumbing, mechanical, and construction trades rely on this grade for demanding joint integrity requirements.

This hex nut is suited for use in both residential and commercial mechanical and structural applications wherever a 5/8-11 UNC thread pattern is specified. It is frequently paired with matching Grade 2H or compatible heavy hex bolts and studs in flanged connections, equipment bases, and structural bolted joints. The 5/8-11 thread designation indicates a coarse-thread series, which provides robust thread engagement in a wide range of base materials.

Key Features

• Grade 2H designation meets heavy hex nut strength and hardness standards for demanding applications
• 5/8-11 UNC coarse-thread profile for broad compatibility with standard 5/8-inch fastener assemblies
• Heavy hex nut geometry provides greater wrenching surface area than standard hex nuts
• Suitable for structural, mechanical, and industrial bolting assemblies

Compatibility

Designed for use with 5/8-11 UNC threaded fasteners in structural and mechanical bolting applications where Grade 2H heavy hex nuts are specified.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, millwrights, or structural ironworkers depending on the application. Always de-energize, depressurize, or shut down the associated system before working on fastened connections. Use a calibrated torque wrench and follow the applicable code or engineering specification for the required torque value. Consult ASME, AISC, or applicable structural standards for torque and joint requirements specific to your assembly.
