A lock nut from the FAG KM line holds bearings and similar components in place on a threaded shaft. Slots machined around the outside of the nut accept a lock washer, which keeps the nut from turning once it is set, so the assembly stays put even where vibration is present. For maintenance and purchasing teams, the nut is what keeps the bearing in its axial position and makes mounting and removal of the assembly easier. MR Industrial Accessories LLC supplies this series within its fastening and retention range.
Reading the code is straightforward: KM comes first, then a number that reflects size. KM0, KM1, KM2, KM3, KM4, KM5, KM6 and KM7 each correspond to a different thread size and diameter, and the figure rises with the nut. That makes it easy to narrow down the right reference, as long as the shaft dimensions and the bearing being secured are checked against it.
You will find these nuts across metalworking, food processing, mining and petrochemical operations, in gearboxes, pumps, fans, conveyors and agricultural equipment. Their job is to hold the bearing in its axial position so it does not shift and damage the rest of the assembly. They suit setups that call for fine adjustment and a fastening that stays tight.
Choosing the right nut starts with two figures: the diameter and pitch of the shaft thread. The bearing to be secured also matters. KM nuts work together with a matching lock washer, which is bent into one of the nut slots to stop it from backing off. At mounting, clean the threads, tighten to the specified torque and check alignment. A lightly lubricated thread makes adjustment smoother and limits wear.
Because KM nuts follow international standards, they can be exchanged between manufacturers when the thread dimensions and slot pattern line up. Always confirm that the lock washer matches as well. To request a quote, send the complete part number, for example KM6, and the team can also suggest equivalents and help with the selection.

Frequently asked questions
- What does the KM designation indicate on these nuts?
- KM identifies the lock nut series, and the number after it gives the size. A higher number means a larger thread diameter, so KM5 is bigger than KM4. The system is standard, which helps when matching a nut to shaft dimensions.
- How does the nut stay locked in place?
- Slots around the nut's contour take a lock washer, such as the MB series. Part of the washer is bent into one slot, which blocks the nut from rotating. It is a straightforward mechanical method that works well under vibration.
- Can a KM nut from one brand be replaced by an FAG one?
- Yes, provided the thread dimensions and slot design are the same. KM nuts are built to international standards and are interchangeable between manufacturers. Check the part number and shaft dimensions to confirm compatibility.
