Threaded Lock Nut 7/16"-20
This pack contains four steel lock nuts with a 7/16 inch diameter and 20 threads per inch. A nylon insert grips the bolt threads to resist loosening caused by vibration or torque. The black chrome finish adds a layer of corrosion protection for the fastener. These components suit automotive repairs and general mechanical assembly tasks.
Vibration Resistance Under Load
The nylon insert creates prevailing torque that maintains clamp force when the joint is subjected to continuous shaking or cyclic stress. Unlike a standard hex nut, the insert deforms around the bolt threads to prevent rotational back-off over time. This locking action remains effective through repeated heating and cooling cycles in the assembly. The steel body sustains the mechanical load without stripping.
Compatibility Check Before Purchase
Verify that the mating bolt or stud uses a 7/16"-20 thread pitch before ordering. Confirm the application does not exceed the temperature limits of the nylon insert material. Ensure the black chrome finish meets the corrosion resistance requirements for the operating environment. Check that the pack quantity of four matches the number of fasteners needed for the job.

Questions about this item
How much power does the 34135 lock nut draw when it is running all day?
The nylon insert lock nut is a passive fastener with no electrical components, so it draws zero power and produces no heat or noise during continuous use.
What thread specification must the mating bolt or stud already have for the 7/16"-20 nut to work?
The nut requires a 7/16 inch diameter bolt or stud with 20 threads per inch to engage correctly.
Will the black-chrome 34135 nut gall or seize when paired with an older plain-steel bolt?
The black chrome finish on the steel nut provides corrosion resistance and reduces the risk of galling when used with a standard plain-steel bolt.
