Value Collection MSC-67470765 Hex Nut 1-1/2-6 Unc Steel

Product Description

The VALUE COLLECTION MSC-67470765 is a heavy hex nut threaded to a 1-1/2-6 UNC specification with a right-hand thread direction. Machined from steel and finished in black oxide, it is designed for high-load fastening applications where a standard hex profile is required. The nut measures 2-1/4 inches across the flats and stands 1-9/32 inches high, making it suited for large-diameter fastener assemblies. Licensed tradespeople and maintenance mechanics reach for this nut when assembling structural connections, heavy equipment mounts, or industrial piping supports that demand a coarse-thread, large-diameter fastener.

This hex nut is appropriate for use in commercial, industrial, and mechanical applications where 1-1/2-inch diameter coarse-thread fasteners are specified. Typical install scenarios include structural steel connections, heavy machinery assembly, flange bolt assemblies, and equipment anchoring. The black oxide finish provides a mild level of corrosion resistance suitable for interior or protected environments. Maintenance technicians, millwrights, pipefitters, and ironworkers commonly use this size in scheduled maintenance and new installation work.

Key Features

• 1-1/2-6 UNC coarse thread for high clamping load in large-diameter applications
• Right-hand thread direction — standard installation orientation
• Steel construction for strength in structural and industrial fastening
• Black oxide finish for mild corrosion resistance and reduced surface glare
• 2-1/4 inches across flats to accept standard heavy hex tooling
• 1-9/32 inches height provides full thread engagement depth

Compatibility

Designed for use with 1-1/2-6 UNC right-hand threaded bolts and studs in steel structural, mechanical, or industrial fastener assemblies.

Installation Notes

Installation is performed by millwrights, ironworkers, pipefitters, or maintenance mechanics using a heavy hex wrench or socket sized to 2-1/4 inches across flats. De-energize and lock out any equipment before fastening or removing hardware on operating machinery. Torque to the value specified by the equipment manufacturer or applicable structural code — do not estimate torque without a calibrated torque wrench on critical connections. Inspect threads for damage or contamination before assembly.
