    product description

    Locking and Non-locking Threads are available.


    These fasteners provide load-bearing threads in thin sheets and permit up to 0.76mm adjustment for mating hole misalignment.


    Extra strength and support in assembly is obtained by the threads of the floating nut extending fully into the retainer shank.


    A self-locking version of the fastener is also offered. Thread locking torque performance is equivalent to applicable NASM25027 specifications.


    Non-locking Type A4 and self-locking Type LA4 fasteners provide load-bearing threads in stainless steel sheets as thin as 0.97mm with hardness up to HRB 88 on the Rockwell “B” scale.
