Wagner Tuning P102021410 Cylinder Head Stud Set for BMW M50/M52 Engine

BMW M50/M52 engine Pro-Series 18.8 cylinder head stud bolt set

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 power 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 need to be replaced after disassembly, but can be reused.

Technical details:
Part number: P102021410
Kit contents:
14 stud bolts (M10)
14 nuts (M10)
14 washers
Assembly lubricant
Assembly instructions

Tensile strength:
Pro-Series 18.8 steel
1850+ N/mm² (270,000+ PSI)

High-quality materials and manufacturing
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.

Easy installation and durability
Pro-Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Thanks to a cone on the engine block side of the stud, 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 during frequent assembly of racing engines. A major advantage of Pro-Series over other manufacturers are the nuts and, if necessary, washers included in the set, as these also have a tensile strength of 1850 N/mm².
