Lock nut with nylon insert
The MIDWEST FASTENER CORP 74305 is a steel lock nut featuring a nylon insert that resists loosening caused by vibration and torque. Its 7/16"-14 thread pitch suits automotive and general hardware assemblies where a secure fastening is required. The chrome-plated finish adds corrosion resistance for extended service life.
Verify thread and clearance
Confirm that the mating bolt or stud uses a 7/16"-14 thread before ordering. Ensure the application provides enough space for the nut height and that the chrome-plated steel material is compatible with the surrounding components and environment.
Vibration resistance over time
Under sustained vibration the nylon insert maintains prevailing torque, keeping the joint tight without the need for secondary locking devices. The steel body handles continuous clamping loads while the chrome plating protects against rust during prolonged exposure.

Questions about this item
Does the 74305 lock nut come individually or in a pack, and do I need to buy a matching 7/16"-14 bolt separately?
The listing shows the 74305 nylon insert lock nut by itself; a compatible 7/16"-14 bolt is not included and must be sourced separately.
Should I choose the chrome-plated steel version or is there another finish listed for the 7/16"-14 size?
Only the steel chrome-plated finish is shown for the 7/16"-14 thread, so that is the version to select.
How does the nylon insert actually stop the 74305 nut from backing off once it is torqued on a 7/16"-14 stud?
The nylon collar grips the 7/16"-14 threads when the nut is tightened, creating friction that resists vibration loosening.
