Value Collection 32289 Hex Jam Nut 7/8-14 Un Steel

Product Description

The VALUE COLLECTION 32289 is a 7/8-14 UN hex jam nut designed for right-hand threaded fastening applications. Manufactured from steel with a zinc-plated finish for corrosion resistance, this low-profile nut measures 1-5/16 inches across the flats and 31/64 inches in height. Hex jam nuts are used as locking elements — tightened against a standard nut or a mechanical stop to resist loosening under vibration or dynamic loads. This part is suited for use in mechanical assemblies, plumbing supports, electrical enclosures, and general industrial fastening work performed by maintenance technicians and trade professionals.

This jam nut is appropriate for use in both light commercial and residential applications wherever a 7/8-14 UN right-hand threaded fastener requires a secondary locking nut. Common install scenarios include threaded rod assemblies, pipe hanger hardware, and equipment mounting brackets. The zinc-plated steel construction makes it suitable for indoor and light-duty outdoor environments where moderate corrosion protection is required. Sold in packages of 25.

Installation Notes

Install using an open-end or combination wrench sized to 1-5/16 inches across the flats. Thread the jam nut onto the fastener and tighten it against the primary nut or mating surface to lock position. Ensure threads are clean and free of debris before installation to prevent cross-threading. Follow applicable mechanical codes and torque guidelines for the host assembly type.
