Strongest premium hexagon bolt

BUMAX supplies premium quality stainless steel hexagon bolts in a variety of dimensions and grades.

BUMAX is the strongest bolt in the world

Stainless steel bolts are often selected due to their corrosion resistance and reduced strength has historically been an accepted compromise of using stainless steel rather than carbon steel. However, BUMAX has changed all this by providing ground-breaking solutions for highly demanding critical applications that require extremely high strength.

BUMAX offers stainless steel fasteners ranging from strength class 8.8 to 16.9. Our products offer a unique combination of strength and good ductility.

Replacing carbon steel fasteners in critical applications

BUMAX premium hexagon bolts are increasingly used to replace high-strength carbon steel bolts in critical applications with extreme requirements on strength, ductility and fatigue resistance. The very high strength to weight ratio in combination with BUMAX good formability and ductility also make it a cost-effective bolt alternative to other lightweight materials such as titanium.

Replacing carbon steel fasteners in critical applications

All BUMAX hexagon bolts are custom made to meet the requirements of each specific application and can be delivered with different mechanical properties.

Customer case story: Satellite sensor

BUMAX high-strength hexagon bolts have proven to be the optimal choice for demanding satellite applications. The Taiwanese National Space Organization (NSPO) required a high strength bolt for its Formosat-5 Earth observation satellite.

The bolts were used to fasten together an Advanced Ionospheric Payload (AIP) at the very front of the satellite. High strength bolts were required as they can cope with a resonance frequency in excess of 120 Hz, which standard stainless steel hexagon bolts simply could not cope with.
