Value Collection 32280 Hex Jam Nut 1-8 Unc Steel 25 Pack

Product Description

The VALUE COLLECTION 32280 is a 1-8 UNC hex jam nut made from steel with a zinc-plated finish. Hex jam nuts are thin profile nuts used to lock a standard hex nut in place, preventing loosening caused by vibration or torque. The 1-8 UNC thread designation indicates a 1-inch nominal diameter with 8 threads per inch in the Unified National Coarse thread standard. With 1-1/2 inches across flats and a height of 0.5469 inches, this nut is sized for use with 1-inch UNC threaded fasteners. This pack contains 25 nuts, making it suitable for job-lot use by maintenance technicians, pipefitters, and mechanical contractors.

This hex jam nut is used wherever a locking fastener solution is needed on 1-8 UNC threaded rod, bolt, or stud assemblies. Common applications include equipment mounting, mechanical assemblies, pipe hanger hardware, and structural bracketing in commercial and industrial settings. The zinc-plated finish provides a basic level of corrosion resistance for indoor and light-duty outdoor installations. Right-hand thread direction follows the standard convention for tightening clockwise.

Installation Notes

Installation requires a standard open-end or box wrench sized for 1-1/2 inches across flats. To use as a jam nut, thread the jam nut onto the fastener first, then thread the standard hex nut against it and torque both nuts against each other to lock them in position. Ensure mating threads are clean and free of debris before installation. Follow applicable mechanical codes and torque guidelines for the specific fastener grade and application.
