Imperial Nyloc Nuts

Nyloc nuts have a nylon insert that grips the bolt thread and resists loosening from vibration. Imperial sizes are needed when repairing or matching machinery built to inch threads. Check the thread form as well as the diameter, because UNC, UNF, BSW and BSF do not interchange.

Our range runs from 3/16" to 2 1/2" in UNC, UNF, UNS, BSW and BSF threads, zinc plated or in A2 stainless.

The nylon insert is not suited to high heat. For metric sizes, see Nyloc Nuts.
