Flange Lock Nut
Mack

Designed for applications requiring a secure and vibration-resistant fastening, this flange lock nut provides enhanced locking capabilities through its integrated flange. It is particularly useful in assemblies where traditional nuts might loosen due to constant movement or vibration, such as in suspension or engine mounting points. The flange distributes load evenly, reducing stress on the fastener and preventing damage to mating surfaces. Its locking feature ensures that the nut remains tight even under extreme operational conditions, which is critical for maintaining safety and performance. This component is a reliable solution for securing critical parts in heavy-duty trucks, ensuring long-term stability and reducing downtime.
