The up to 30% stronger expansion steel of ARP products can withstand higher loads and pressures. The tensile strength is about 1400 N/mm². For comparison: a standard 10.9 screw only has a tensile strength of 900 N/mm".
With ARP screws / stud bolts, even extremely high boost pressure can be driven without any problems regarding the bolting of the cylinder head to the block. The strauben / stud bolts are made of 8740 chrome-molybdenum steel and have rounded threads.
