HMZ系列开槽锁紧螺母可以使轴承实现在圆柱或圆锥轴上，或在紧定套上的精确及可靠的轴向定位，它们已经成功应用于造纸机、风力涡轮机。
HMZ系列锁紧螺母可与传统HM和KM系列锁紧螺母互换。它们通过压力锁紧而不是通过垫圈或卡板来固定住。四个或八个轴向紧固螺钉使得锁紧螺母在圆周方向上的锁紧力一致。将该锁紧螺母安装在轴上时，只需在螺母外圆上相应的四或八个盲螺孔中旋入螺杆作为安装手柄即可。不需要在螺母外径上开槽或附加任何止动件。由于轴上不必有止动槽，其强度会更高、生产更为经济。
- 抗拉强度不小于350N/mm²
- 表面涂层可选：锌磷酸化、Corrotect、电镀等
- 螺纹直径200mm以下细牙螺纹等级6H，较大直径的梯形螺纹等级7H
