Discover more about the Bumax Collar Locking Nuts range.

Bumax Collar Locking Nuts feature a uniquely designed thread profile which distributes tensile stress along the thread of the entire nut, causing this component to lock when tightened. This design increases load-bearing capabilities, and enhances the gripping strength of the nut. These properties, combined with the mechanical properties of Bumax Stainless Steel, create a durable and hard-wearing component, suitable for heavy-duty applications.


Bumax Stainless Steel is known as one of the strongest and most resilient grades of Stainless Steel in the world. Bumax 88 has a minimum tensile strength of 800N/mm², low magnetic permeability, and excellent resistance to corrosion and heat.


Bumax Collar Locking Nuts are manufactured in metric thread sizes of between M12 and M20.
