A centering pin arrangement for clamping a substrate with a hole with radius r<SUB>max </SUB>comprises two bolts ( 2, 3 ) with an essentially semicircular cross section K, said bolts having radii r<SUB>2 </SUB>and r<SUB>3 </SUB>respectively. Said radii r<SUB>2 </SUB>and r<SUB>3 </SUB>are different and at least one of the bolts ( 2, 3 ) has a radius bigger or equal to the radius r<SUB>max </SUB>of the hole. In another embodiment both radii r<SUB>2 </SUB>and r<SUB>3 </SUB>are bigger than the radius r<SUB>max </SUB>of the hole. |
