New from Laser Tools: internal and external KM Lock Nut socket sets

Laser Tools introduces two precision-engineered socket sets for KM groove nuts, essential for securing bearings to shafts or housings. A KM groove nut is a specialised type of nut designed to secure bearings, gears, or other components on a shaft. It is often used in conjunction with a lock washer or other locking devices to ensure that the nut remains securely in place during operation, even under conditions of vibration or rotation.
