Competition Stud Conversion Kit

All Macht Schnell Competition fasteners are hardened and tempered to strength class 10.9 or 10 according to DIN/ISO standard 898. They meet the statutory requirements of all countries - including the USA.

All studs/nuts feature a black plating process for OEM appearance.

Final inspections are not restricted to random quality checks. Every single fastener is tested to ensure compliance with specifications. Studs/nuts are also offered individually and should be replaced after every race season.
