Value Collection 314440BR Heavy Hex Nut 1-3/8-6 Unc

Product Description

The VALUE COLLECTION 314440BR is a heavy hex nut designed for high-strength bolted connections in structural, industrial, and mechanical applications. Manufactured from A194 Grade 2H steel with a bright uncoated finish, this nut meets the dimensional and material standards set by ASME B1.1 and ASME B18.2.2. It features a 1-3/8-6 UNC right-hand thread with a 2B fit class, providing reliable engagement across a wide range of compatible heavy hex bolt configurations. At 1.02 pounds per unit, it is suited for heavy-duty service where standard hex nuts are not rated for the load. Trades such as structural iron workers, industrial pipefitters, and millwrights commonly specify this grade for high-temperature or high-pressure assemblies.

This heavy hex nut is used in structural steel construction, pressure vessel assembly, piping flanges, and industrial equipment mounting. Its A194 Grade 2H designation makes it appropriate for bolted flange joints and structural connections that require controlled hardness and elevated load capacity. The uncoated finish is suitable for applications where additional coatings or gaskets will be applied in the field or where environmental exposure is managed by the installer.

Key Features

• A194 Grade 2H steel construction with hardness range of 24-35 HRC for high-strength bolted joints
• 1-3/8-6 UNC right-hand thread, 2B fit class, conforming to ASME B1.1
• Heavy hex profile with 2-3/16 inches across flats per ASME B18.2.2
• Bright uncoated finish — no plating to affect dimensional tolerance or conductivity
• Height of 1-11/32 inches providing additional bearing surface versus standard hex nuts

Compatibility

Designed for use with 1-3/8-6 UNC heavy hex bolts and threaded rod conforming to ASME B1.1 dimensional standards. Intended as a heavy hex nut replacement or new installation component in structural and industrial bolted assemblies requiring A194 Grade 2H material compliance.

Installation Notes

Installation is performed by qualified tradespeople using calibrated torque wrenches or hydraulic tensioning equipment appropriate to the joint specification. Power down or de-energize any associated systems before working on bolted connections in electrical or pressurized service. Follow the applicable fastener torque specifications from the engineering drawings or applicable code — no torque values are published here. Inspect threads for damage or contamination before assembly to ensure proper 2B fit engagement.
