HARDLOCK-LUGNUT

HARDLOCK-LUGNUT will not loosen the tension rods. It was developed with “HARDLOCK Industry Co., Ltd.“, which produces the world-recognized "ultimate locking nut." The strong anti-loosing effect of the wedge prevents loosening by strongly locking the tension rod with the nut. It also has an innovative feature that allows you to adjust the tension rod without loosening it even if it is locked.
