FAQ

What is the material V2A and why is it important for a lock nut?

V2A is a grade of stainless steel (equivalent to AISI 304) that offers excellent corrosion resistance. This is crucial for applications in humid, wet, or chemical environments where a standard steel nut would rust and potentially fail.

Which locking device is compatible with a KM 14 lock nut?

The KM 14 lock nut is designed to be used with an MB 14 lock washer. The inner tab of the washer fits into a keyway on the shaft, and one of the outer tabs is bent into one of the four slots on the nut’s circumference to prevent it from loosening due to vibration or rotation.

What are the exact thread specifications for a KM 14 nut?

The KM 14 lock nut has a standard metric fine thread of M70x2, which means it has a nominal diameter of 70 mm and a thread pitch of 2 mm.
