BUMAX 88 is one of our flagship stock grades that provides higher strength, corrosion resistance and fatigue performance than 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 NITRO 109 is a nitrogen-strengthened austenitic stainless steel that provides superior corrosion resistance and strength for large size bolts.
BUMAX SA is a 6Mo high-alloy austenitic stainless steel for aggressive chloride applications.
BUMAX HE is a high-temperature resistant grade for applications requiring high strength and good oxidation resistance at temperatures up to 700°C.
BUMAX ULTRA 159 is a unique precipitation-hardened stainless steel that provides ultra-high strength in class 15.9, while maintaining outstanding ductility.
