Value Collection 39609 7/8-9 Unc Steel Hex Nut

Product Description

The VALUE COLLECTION 39609 is a 7/8-9 UNC steel hex nut with a right-hand thread direction, designed for general-purpose fastening applications. The nut measures 1-5/16 inches across the flats and stands 3/4 inches high, making it a standard heavy-fastener size suited for structural, mechanical, and industrial assemblies. It carries a zinc yellow dichromate finish, which provides a baseline level of corrosion resistance appropriate for indoor and mildly exposed environments. Electricians, plumbers, HVAC technicians, and general mechanical contractors use fasteners of this type when securing equipment frames, support brackets, and hardware to threaded rod or bolt assemblies.

This hex nut is suited for use wherever a 7/8-9 UNC threaded fastener is specified. The UNC (Unified National Coarse) thread standard is the most widely used inch-series thread form in North American trade and industrial work. Right-hand threading means the nut tightens in the standard clockwise direction. Typical applications include mechanical equipment mounting, structural steel connections, and general maintenance and repair operations across HVAC, plumbing, electrical, and light industrial trades.

Key Features

• 7/8-9 UNC thread size with right-hand thread direction
• 1-5/16 inches across flats for standard wrench engagement
• 3/4 inches high — standard hex nut height for this thread size
• Steel construction for mechanical strength and durability
• Zinc yellow dichromate finish for baseline corrosion resistance

Compatibility

Designed for use with 7/8-9 UNC threaded fasteners following the Unified National Coarse inch-series thread standard, common in North American mechanical and structural applications.

Installation Notes

Install using a standard 1-5/16-inch open-end, box, or socket wrench. Power down or de-energize any associated equipment before working on fastened assemblies in electrical or HVAC contexts. Do not overtighten — apply torque in accordance with the fastener manufacturer's specifications or the governing project specification. Ensure mating bolt threads are clean and free of debris before assembly.
