Discover more about the Bumax Flanged Locking Nuts range.

Bumax Flanged Locking Nuts feature a specially designed thread profile which distributes tensile stress along the thread of the entire nut, causing this component to lock when tightened. This unique 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 very durable fastener, 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 Flanged Locking Nuts are manufactured in metric thread sizes of between M6 and M12.
