Auto-Lok Nut - ALNssnM - Self Locking Lock-Nuts

We advise not to use this nut, as the metal ring cuts into the material of the bolt.  It might damage the bolt, and make the re-usability of the nut doubtfull.

please use the double slotted joining lock nut as better solution.

self-locking fine pitch nuts with metal inserts are available too, consult us.
