Value Collection 289098BR Heavy Hex Nut 1-1/2-6 Unc

Product Description

The VALUE COLLECTION 289098BR is a heavy hex nut sized 1-1/2-6 UNC, manufactured from Grade 2 steel with a bright, uncoated finish. It features a right-hand thread with a 2B fit class, meeting ASME B1.1 and ASME B18.2.2 fastener standards. The wider hex profile of a heavy hex nut provides greater bearing surface and improved torque resistance compared to a standard hex nut, making it well suited for structural and industrial fastening applications. Licensed trades and general contractors use this type of fastener where robust clamping force is required on larger-diameter threaded assemblies.

This heavy hex nut is appropriate for use in structural steel connections, heavy equipment assembly, and industrial maintenance applications requiring a 1-1/2-6 UNC thread. The uncoated finish suits indoor or controlled-environment installations where corrosion is not a primary concern. It is commonly paired with matching Grade 2 or higher-grade hex bolts or threaded rod in both residential and light commercial construction settings.

Key Features

• Heavy hex profile with 2-3/8 inch width across flats for increased bearing surface
• 1-1/2-6 UNC right-hand thread with 2B fit class for consistent engagement
• Grade 2 steel construction with hardness range of 68 HRB to 32 HRC
• Meets ASME B1.1 and ASME B18.2.2 fastener standards
• Bright uncoated finish — ready for use or field coating as required
• Does not meet military specifications

Compatibility

Designed for use with 1-1/2-6 UNC threaded bolts, studs, or threaded rod. Verify thread standard and fit class compatibility with mating fasteners before installation.

Installation Notes

Installation is typically performed by structural ironworkers, millwrights, or maintenance mechanics using appropriate wrenches or impact tools sized for a 2-3/8 inch hex. Follow applicable torque guidelines per the governing code or structural engineer of record for the project. Inspect threads on both the nut and mating fastener for damage before assembly. Do not exceed the torque capacity of Grade 2 hardware in high-stress structural joints where higher-grade fasteners are specified.
