BUMAX® 109 is your first choice for better corrosion resistance and strength in demanding applications.
The strongest fastener on the market
BUMAX® 88 and BUMAX® 109 have the same material composition but due to different manufacturing processes, BUMAX® 109 provides even higher strength than BUMAX® 88 and is the strongest A4 fastener on the market.
Fasteners with enhanced properties
BUMAX® 109 outperforms standard A4 fasteners in terms of:
- yield strength
- corrosion resistance
- mechanical properties
- magnetic permeability
These enhanced properties are achieved through a higher molybdenum content (minimum 2.5%), our unique manufacturing processes and sourcing of highest quality European raw material. In addition, all our products offer full traceability with 3.1 certificates on request.
Fasteners for demanding applications
BUMAX® 109 fasteners are used for water jets, sub-sea equipment, pumps, valves, wind turbines, high-pressure equipment, nuclear plants, submarines, particle accelerators and many other applications where commodity A4 fasteners are inadequate. As a result, BUMAX fasteners provide greater safety and will last significantly longer than standard A4 fasteners.
