Wagner Tuning Burnished Head Stud Set for FK8 Honda Civic Type R

The Wagner Tuning Burnished Head Stud Set for the FK8 Honda Civic Type R is designed to deliver the clamping force required for high-output and high-boost applications where factory head bolts can become a limitation. This kit replaces the OEM cylinder head bolts with Wagner Tuning Pro-Series 18.8 high-strength stud bolts, rated at an exceptional tensile strength of 1850 N/mm², effectively preventing bolt stretch and cylinder head lift under increased performance demands. Featuring a black oxide Burnished finish for durable corrosion protection and long-term reliability, these reusable studs do not require replacement after disassembly, making them a dependable solution for serious performance builds focused on strength, durability, and serviceability.

High-Quality Materials and Production

• Wagner Tuning manufactures its Pro-Series 18.8 stud kits in Germany using specially engineered high-strength steel. After heat treatment, the studs achieve a tensile strength exceeding 1850 N/mm². All threads are roll-formed rather than cut, increasing thread flank strength by approximately 30 percent. Each Pro-Series fastener is finished with a black oxide burnished coating that provides long-lasting corrosion resistance, even under extreme operating conditions.

Easy Installation and Durability

• Wagner Tuning designs the Pro-Series stud bolts with an internal hex drive on the head side for precise and controlled installation. A conical support section on the engine block side ensures clamping force is transferred against the bore instead of the thread flanks when the nuts are tightened, helping protect engine block threads during repeated assembly, particularly in motorsport applications. Each kit is supplied with matching high-strength nuts and, where required, washers that meet the same 1850 N/mm² tensile strength rating, offering a clear durability advantage over many alternative fastener solutions.
