KM系列和KML系列锁定螺母计与锁定垫圈一起使用，在其圆周上具有四个等间隔的槽以承载钩形扳手或冲击扳手，也称为圆螺母，可以用MB垫圈锁定。KML系列锁定螺母的截面高度低于KM系列锁定螺母。
HM..T系列锁定螺母为带公制梯形螺纹的拆卸螺母，对于一些尺寸，没有锁定垫圈可用，因为这些螺母旨在从退卸套卸下圆锥孔轴承。其中 44、48、52、56 系列可通过 MB 锁紧垫圈锁定在轴上。HM..T系列锁紧螺母可以重复使用。
- 公差：KM/KML系列为5H；HM..T系列为7H
- 配合轴螺纹：KM/KML系列公制螺纹 6g；HM..T系列为7e
- 定位面/螺纹轴向跳动：KM/KML系列为0.04 ~0.06 mm；HM..T系列为0.06~0.16mm
