ARP are known the world over in the motorsport and high performance vehicle circles as the premier bolts if you want the best of the best!
Made in the U.S.A
- Tensile strength of the 8.8 grade is 800mPa or 116,000psi
Tensile strength of the ARP (8740 chromoly) is 1310mPa or 190,000psi
Tensile strength of 12.9grade is 1200mPa or 170,000psi
Thats a 63% increase over 8.8 grade, and a 10% increase over 12.9 grade.
The other factor to consider here is – all grade 8.8 and 12.9 bolts are coming from China. You really do have to ask yourself…are they really undergoing continuous quality control in terms of yield tensile strength? Most people will realise ARP are 🙂
This is the very reason motorsport and performance applications use and trust ARP
