DIN 981 KM Rolling Bearing Lock Nut automotive fastener

These Slotted Round Nuts are meticulously crafted from high-quality Stainless Steel A2 (AISI 304) and A4 (AISI 316) options, ensuring excellent corrosion resistance and durability across diverse operating environments. The precise threading and dimensional accuracy guarantee a reliable and secure fit, crucial for maintaining bearing integrity and extending service life.

Designed for Ease of Use:

Our DIN 981 KM Rolling Bearing Lock Nuts are engineered with user-friendliness in mind, simplifying the bearing mounting and dismounting process:

• Slotted Design: The integrated slots around the circumference of the nut provide a secure engagement point for hook spanners or impact wrenches, allowing for controlled and effective tightening. This design minimizes the risk of damage to the shaft or bearing during installation.
• Precise Threading: Manufactured with accurate metric threads (ranging from M101.75 to M2003.0, covering sizes KM0 to KM40), our lock nuts ensure a perfect fit with compatible shafts, facilitating consistent and reliable clamping force.
• Material Options: The availability of both Stainless Steel A2 and A4 grades allows you to select the optimal material for your specific application, considering factors such as corrosion resistance in humid, chemical, or marine environments.
