Product Description

This simple locknut is produced by installing 3 deflections in alternate flats precisely in the center the jam nut hex. The low cost of the basic jam nut and typical high volume production make the Jam Hex Center Locknut relatively inexpensive. Jam Hex Center Locknuts are not required to meet the thread start or torque requirements of Full Hex Center locknuts.

Applications

Jam Hex Center locknuts are selected when the application demands a low profile and can accept the proof load of the thinner jam nut. The center locknut can be installed from either direction, simplifying automatic feed or speeding hand assembly. Mating parts must only extend to flush with the jam nut top surface to assure locking element engagement.
