Value Collection 342532MSC Hex Nut 1-3/4-5 Unc Grade 2

Product Description

The VALUE COLLECTION 342532MSC is a heavy hex nut with a 1-3/4-5 UNC thread size, manufactured from Grade 2 steel with a bright, uncoated finish. It features a right-hand thread and a 2B fit class per ASME B1.1 and ASME B18.2.2 standards. The nut measures 2.75 inches across flats and 31/32 inch in height. This fastener is suited for general-purpose bolted assemblies where high-strength alloy hardware is not required. Licensed tradespeople, maintenance technicians, and fabricators working across mechanical, structural, and industrial applications install this type of hardware daily.

This hex nut is appropriate for use in low-to-medium load bolted connections in residential, commercial, and light industrial settings. Typical applications include structural framing connections, equipment mounting, general mechanical assemblies, and maintenance repair work where a standard UNC thread pattern is specified. The uncoated finish is suitable for indoor or protected environments where corrosion exposure is minimal.

Key Features

• 1-3/4-5 UNC right-hand thread for standard coarse-thread bolt engagement
• Grade 2 steel construction meeting ASME B18.2.2 fastener standards
• 2B thread fit class per ASME B1.1 for reliable mating with standard UNC bolts
• 2.75 inches across flats for use with standard hex wrench or socket tooling
• Bright uncoated finish — suitable for dry or protected indoor installations
• Hardness rated at 95 HRR for general-purpose load applications

Compatibility

Designed for use with 1-3/4-5 UNC threaded bolts and studs conforming to standard coarse-thread series specifications under ASME B1.1 and ASME B18.2.2.

Installation Notes

Installation is performed by mechanics, ironworkers, millwrights, or maintenance technicians using a standard hex socket or open-end wrench sized for a 2.75-inch across-flats dimension. Confirm thread engagement and alignment before applying torque; cross-threading a large-diameter nut can damage both the nut and mating fastener. De-energize, depressurize, or unload any assembly before removing or replacing fasteners under load. Follow applicable structural or mechanical codes for torque requirements specific to the joint design and bolt grade.
