Qty of 75 Brand New 1/2-13 Automation Locknut Grade A Zinc Plated The top thread section of the Automation Locknut is precisely displaced at two 180° opposing areas. This deflection ovalizes the top threads of the nut and bends these threads out of their helical configuration. This locking element remains spring-like through repeated applications and severe shock loads.
