Global manufacturer, BUMAX, offers premium stainless steel fasteners in a variety of steel grades that provide optimal safety and reliability in the most demanding customer applications.
In fact, the BUMAX Ultra has proven itself as the “world’s strongest bolt” – in various highly-demanding critical fastener applications around the world where standard fasteners are simply inadequate. BUMAX produces the strongest fasteners in the world by drawing on Nobel Prize winning quasi-crystalline Precipitate technology.
The technique uses strain hardening followed by precipitation hardening, which significantly increases tensile strength.
Since its launch in 2014, the BUMAX Ultra range has proven that it is capable of exceeding tensile strengths of between 1 500 to 1 700 MPa on various applications, with good corrosion resistance and an operating range of between -50 and 400° C.
BUMAX Ultra is designed for applications that require ultra-high strength combined with high ductility and fatigue. The technique also provides better corrosion resistance than A2 (304) and with low thermal expansion it is suitable for high service temperatures. These components are used for security lock systems, aerospace systems, high-pressure applications, and pump and valve systems.
The extreme strength of BUMAX Ultra fasteners also provides opportunities to downsize to new lightweight fastener options at lower cost.
