The BUMAX® 88 and 109 fasteners are developed to achieve ultimate tensile and yield strength values in line with those of Steel-screws in class 8.8 and 10.9. The BUMAX products can also give top performance long after standard fasteners have reached their limits. The difference compared to conventional products is especially noticeable in extreme environments.

• Class 8.8 and Class 10.9 Strength
