FAQ

What is the correct locking washer to use with a KM07 lock nut?
The standard corresponding locking washer for a KM07 nut is the MB7 locking washer.

What is the recommended tightening procedure for this nut?
The tightening procedure is application-dependent. Generally, the nut is tightened to remove all axial clearance in the bearing, then slightly loosened to allow for free rotation before one of the tabs of the locking washer is bent into a slot on the nut to secure it.

Is this lock nut made from stainless steel?
Standard KM series lock nuts are manufactured from high-strength carbon steel. If your application requires corrosion resistance, a specific stainless steel version should be sourced.
