“BUMAX was the only solution that fully met our requirements while still being cost effective.”
Mathijs Baars
Mechanical Engineer at the Dutch National Institute for Subatomic Physics
“We required a 10.9 strength bolt, but with the corrosion resistance of stainless steel. BUMAX offered us the perfect solution.”
Michael Evers
Project Manager at VDL ETG
BUMAX 88 is one of our flagship stock grades that provides higher strength, corrosion resistance and fatigue performance than A4-80 generic stainless steel fasteners.
BUMAX 109 is one of our flagship stock grades that offers higher strength than A4-100 and is the strongest A4/316 stainless steel fastener on the market.
BUMAX DX 129 is a duplex stainless steel grade with very high strength combined with excellent corrosion resistance.
BUMAX NITRO 109 is a nitrogen-strengthened austenitic stainless steel that provides superior corrosion resistance and strength for large diameter bolts.
BUMAX HE is a high-temperature resistant grade for applications requiring high strength and good oxidation resistance at temperatures up to 700°C.
