Wagner Tuning GR Supra B58 OEM Head Stud Set - Burnished

Overview

This set replaces the original cylinder head bolts with high-strength Pro-Series 18.8 stud bolts. This is necessary in the case of significant performance increases, as the original cylinder head bolts can elongate during operation and the cylinder head can lift off. The Pro-Series 18.8 stud bolts with a tensile strength of 1850 N/mm² provide a remedy for this. In addition, these stud bolts do not have to be replaced after disassembly, but can be reused.

The Pro-Series 18.8 sets are high-strength stud bolts made in Germany. A special steel is used, which has a tensile strength of 1850+ N/mm² after tempering. All threads are formed and not cut as is customary in the trade. By rolling the threads, the strength of the tooth flanks can be increased by around 30%. All Pro-Series products are supplied with a nickel coating or optionally with a burnished finish and are therefore protected against corrosion in the long term, even under the toughest conditions.
