Value Collection 330410PR Hex Jam Nut 7/16-20 Unf

Product Description

The VALUE COLLECTION 330410PR is a 7/16-20 UNF hex jam nut manufactured from Grade 2 steel with a zinc-plated finish. Jam nuts are thin hex nuts used to lock a standard nut in place or to fasten components where minimal thread engagement is required. This nut features a right-hand thread, measures 11/16 inches across the flats, and stands 1/4 inch tall. The zinc coating provides basic corrosion resistance for general-purpose indoor and outdoor fastening applications. At 0.05 pounds per unit, it is suited for assemblies where weight is a factor.

This jam nut is appropriate for general mechanical assemblies, HVAC equipment mounting, plumbing fixture hardware, and light structural fastening where a locking or spacing nut is needed. The 7/16-20 UNF fine thread pitch provides tighter thread engagement per inch compared to coarse thread, making it a common choice in vibration-prone environments. It is used by HVAC technicians, plumbers, electricians, and general mechanical trades in both residential and commercial settings.

Key Features

• 7/16-20 UNF fine right-hand thread for tighter engagement in vibration-prone assemblies
• Grade 2 steel construction suitable for general-purpose fastening loads
• Zinc-plated finish for basic corrosion resistance
• Jam nut profile at 1/4 inch height for locking or low-clearance applications
• 11/16 inch across flats fits standard 11/16 inch open-end or combination wrench

Compatibility

Designed as a general-purpose 7/16-20 UNF jam nut compatible with any standard 7/16-20 UNF threaded rod, bolt, or stud requiring a right-hand thread locking or thin-profile nut.

Installation Notes

Installation requires a standard 11/16 inch open-end, combination, or socket wrench. Power down or de-energize any equipment before accessing fastener locations on electrical or HVAC assemblies. When used as a locking jam nut, tighten the primary nut to the required position first, then back the jam nut firmly against it while holding the primary nut stationary. Do not substitute jam nuts for full-height structural nuts in load-bearing applications without verifying fastener grade and engagement requirements.
