This upgrade is necessary when making large increases in performance, as the OEM cylinder head studs elongate during operation, and the cylinder head can lift. The Pro-Series 18.8 Stud Bolts have a tensile strength of 1850+ N\/mm² (268320+ PSI) and are designed to be the perfect solution for upgraded head studs. Unlike factory head studs, the Wagner Pro Series Studs do not need to be replaced after dismantling and can be reused. \u003cbr\u003e\u003cbr\u003e The Pro-Series 18.8 sets are high-strength stud bolts manufactured in Germany. A special steel is used which, after tempering, has a tensile strength of 1850 + N \/mm². All threads are formed and not cut as usual. The so-called rolling of threads can increase the strength of the tooth flanks by around 30%. All Pro-Series products are supplied with a nickel coating or optional with a burnished finish, protecting against corrosion in the long term, even under the toughest conditions. Pro-Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Due to a cone on the engine block side of the bolt, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads when racing engines are frequently rebuilt. Pro-Series advantage over other manufacturers is the nuts and washers included in the set, these also have a tensile strength of 1850 N \/ mm². \u003c\/p\u003e \u003ch3\u003eWhy M11 Head Studs over M10 Head Studs?\u003c\/h3\u003e \u003cp\u003e Wagner M11 Head Studs offer a 23% increase in clamping force compared to M10 Head Studs. In our testing, we have found that additional clamping force is beneficial for EA839 Stage 3 builds that are often running high output files, and thus recommend installing M11 Head Studs with any Stage 3 high output build. \u003cbr\u003e\u003cbr\u003e 034Motorsport engineers are working on a simple tool to allow the necessary Head, Head Gasket, and Engine Block modifications to be done at home
