At the \u003cstrong\u003eDIY Hardware Store\u003c\/strong\u003e, our nylon insert nuts are available in the metric sizes used across automotive, engineering, machinery, and general assembly applications where nut retention is required without secondary locking devices.\u003c\/p\u003e\n\n\u003cp\u003eThe nylon insert sits in the top of the nut above the metal thread. When the bolt passes through the metal thread and encounters the nylon insert, it deforms the nylon slightly to cut a mating thread - this interference creates a significant prevailing torque that prevents the nut from rotating backwards on the bolt under vibration. The nut can be removed with a spanner, but will not loosen spontaneously in service.\u003c\/p\u003e\n\n\u003cp\u003eNyloc nuts are single-use in theory - the nylon insert compresses permanently on first installation - but in practice they can often be reused a limited number of times if undamaged.
