How to choose Lock nuts

Points to check when selecting, with the values for this product (KMK Integrated Fixture Lock Nut).

  1. 1. Select the size and standard to match the shaft thread

    This product: Nominal thread size G M10x0.75~M100x2

    The nut must fully match the thread of the shaft or sleeve. Metric fine pitch such as M10×0.75, trapezoidal threads such as Tr220×4, and inch series (ANSI/ABMA) are all listed, so verify the nominal diameter, pitch, and thread standard against the drawing.

  2. 2. Do not confuse thread standard series

    Metric KM and HM series and inch N and AN series may look similar but are not interchangeable. Some larger sizes in certain series use trapezoidal threads, so confirm the original standard when repairing existing equipment.

  3. 3. Decide the anti-rotation method

    Methods using lock washers, fixing clips, or locking plates require a keyway on the shaft. Integrated types that rotate-lock with set screws or locking pins do not require a keyway and allow quick installation. Also confirm whether accessories are required.

  4. 4. Verify axial load capacity

    This product: Axial load capacity 20~122 kN

    Nuts receive thrust loads and pressing force during tightening. Listed axial load capacities range widely from 20 to 1340 kN, so confirm sufficient margin against the axial load on the bearing and the force required to press onto a tapered shaft.

  5. 5. Check side face runout for precision applications

    In applications such as main spindles with high rotational speed and accuracy, if the nut side face runs out relative to the thread, the bearing tilts and rotational accuracy decreases. Select a precision lock nut and check the axial runout value of the reference side face.

  6. 6. Check outer diameter and width for clearance

    Confirm that the nut outer diameter does not interfere with housings or seals, and that the width fits within the thread length of the shaft. Also confirm the applicable spanner number used for tightening and the recommended tightening torque.
