Value Collection 31209 7/8-9 Unc Steel Hex Nut Zinc-plated

Product Description

The VALUE COLLECTION 31209 is a 7/8-9 UNC hex nut machined from steel and finished with a zinc-plated coating for corrosion resistance. It features right-hand threading to the Unified National Coarse (UNC) standard, measures 1-5/16 inches across the flats, and stands 3/4 inches high. This nut is a standard fastener used across mechanical, structural, and trade applications wherever a 7/8-9 UNC threaded fastener requires a mating nut. Installation requires a standard hex wrench or socket. The zinc plating provides a protective barrier against mild corrosion in typical indoor and sheltered outdoor environments.

This hex nut is suited for general-purpose fastening in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure work, and light structural applications. It is appropriate for use by licensed trade professionals and maintenance technicians working on equipment that calls for 7/8-9 UNC threaded connections. The right-hand thread direction is the conventional standard for the vast majority of mechanical fastening applications.

Key Features

• 7/8-9 UNC right-hand thread for standard mechanical fastening
• Steel construction provides strength and durability under load
• Zinc-plated finish adds corrosion resistance in typical service environments
• 1-5/16 inches across flats for standard hex wrench or socket compatibility
• 3/4 inches height suits standard hex nut engagement depth requirements

Compatibility

Designed as a standard replacement or supplemental hex nut for any 7/8-9 UNC threaded bolt or stud application requiring a right-hand steel hex nut.

Installation Notes

This nut is installed by qualified tradespeople using a standard hex wrench or socket sized for 1-5/16 inches across flats. Ensure the mating bolt or stud is clean, undamaged, and confirmed to be 7/8-9 UNC right-hand thread before installation. De-energize or shut off any relevant systems before accessing fasteners in live equipment. Do not overtighten; refer to the equipment manufacturer torque specifications for the assembly being serviced.
