Jam Nuts from Fabory for a More Secure Fit

Jam nuts, a specialised hardware component, are thinner than standard nuts and are designed with a primary focus on securing threaded fasteners against loosening under vibration and torque. Their low profile makes them ideal for applications with limited space. These nuts, often overlooked but crucial, play a significant role in various mechanical assemblies. They are particularly essential in environments subject to high vibration or dynamic loads, where maintaining joint integrity is of utmost importance.

Jam nuts are commonly employed in the automotive, aerospace, and manufacturing industries. Tightening a jam nut against a standard nut on the same bolt or threaded rod acts as a locknut, preventing the primary nut from turning and loosening over time. This functionality is vital for ensuring the stability and safety of the assembly in challenging conditions.

When selecting jam nuts, several key factors must be considered. The choice of material affects the nut's strength, corrosion resistance, and suitability for specific environments, with standard options including stainless steel and carbon steel. Choosing a jam nut that matches the thread size and type of bolt or stud it will be used with is crucial to ensure a secure fit. Additionally, consider the mechanical and environmental demands of the application, such as exposure to extreme temperatures or chemicals. Lastly, the nuts must meet standards like ISO and DIN to guarantee reliability and compatibility with other components.
