Find the optimal grade for your fastener application
By comparing the properties of different grades, such as mechanical strength, corrosion resistance, magnetic permeability, temperature resistance and fatigue strength, you can quickly identify the best BUMAX grades for your particular application. The tool allows you to compare up to three different grades at once.
These tools should be used for guidance and as part of a comprehensive engineering approach. Contact our technical team for additional support and advice.
