BUMAX provides high-quality fasteners that are certified to international and third-party standards.
The majority of our fasteners are cold forged at our own facilities in Sweden where we have made cold forged stainless fasteners since 1926. Cold forging provides a superior product with increased strength and enhanced fatigue resistance.
We source stainless steel from premium suppliers in Europe according to rigid specifications on chemical composition, a low content of trace elements, as well as low inclusion and slag content.
All our BUMAX products are delivered with full traceability and 3.1 certificates, and we can offer 3.2 certificates on demand. BUMAX 88 can also be delivered with a certificate that ensures that our fasteners are in accordance to the European Union’s pressure equipment directive (PED97/23) as well as with CE marking for structural bolts according to EN 15048.
Our facilities are approved according to ISO 9001, ISO 14001 and IATF 16949.
Our certificates can be found in downloads.
Own lab capabilities
All BUMAX products are tested and documented in our own lab in terms of tensile strength, hardness and material composition. On demand, we can also provide friction and Junker testing. All our measuring instruments are continuously calibrated.
