    Advantages:

    ● Anti-loose, anti-vibration, anti-theft, convenient for assembly and disassemble, repeated use

    ● This check nut can lock the bolt tightly by upper and lower nuts with eccentric thread, no loose off during violent shake

    ● The check effect can ensure the safety and reduce maintenance costs 

    ● Stable locking force can prevent or postpone the failure of the bolt and improve the life of whole connection system

    ● The best choice for long-term impact, vibration and time-dependent loading



    Suitable for equipment fixing and fastening

    Match with NJMKT mechanical anchors to achieve perfect effect

    Instruction guide:

    ● Lock the overall nuts firstly, then tighten the nut to lock; dislocate the above marked sign to less than 90 degrees, then it reaches the lock-up effect. 

    ● There is no loose off in severe vibration, so it avoids the trouble of shutdown maintenance caused by common nut loosening.
