M48 x 75.0mm Nord-Lock® Washer | Delta Protekt® Hardened Steel | Vital Parts - NL-M48-75-DPT
The M48 x 75.0mm Nord-Lock® Washer | Delta Protekt® Hardened Steel is a precision-engineered locking washer pair developed to reduce the risk of rotational loosening in service. The M48 format incorporates a 49.6mm bore, a 75.0mm outer diameter and a total thickness of 7.00mm. The Delta Protekt® hardened steel specification makes this option suitable for general machinery, fabrication and steel construction assemblies. Its locking principle helps protect equipment uptime by reducing the likelihood of vibration-induced loosening.
What Are Nord-Lock® Washers?
Unlike conventional friction-based lock washers, Nord-Lock® washers use cam geometry to secure the bolted joint. The two washers are fitted cam-to-cam, leaving their serrated faces outward. When the fastener tries to rotate, the cams force an increase in bolt tension, which opposes further loosening.
Common Applications

- Energy Equipment: Suitable for turbine auxiliaries, generators and other mechanically loaded plant assemblies.
- Mining Equipment: Helps secure high-load connections exposed to shock, vibration and abrasive operating conditions.
- Heavy Plant: Supports critical bolted joints on excavators, crushers and large production machinery.
