Apply the Correct Torque More Reliably
Correct locknut installation depends on applying the specified tightening torque. Conventional hook wrenches engage the locknut at a single slot, which can make it harder to transfer and control the applied torque consistently.
Our socket/collar-type mounting tools engage the locknut at three or four slots and allow you to apply torque more directly with a torque wrench. This gives you better control during installation, reduces the risk of slipping or damaging the locknut, and helps you tighten the locknut to the required setting.
Choosing Between Collar and Socket
Open ring
NIKKI Collar is a flat open ring that fits around the locknut and leaves the centre clear, so it works where the shaft continues past the nut. It is the more universal of the two, covering both ends of a spindle and both ends of a ball screw.
Closed cup
NIKKI Socket is a closed cup that drops over the locknut and the shaft end behind it. It needs clear space beyond the nut, so it suits the rear end of a spindle or the pre-tensioned end of a ball screw.
