Description

These are the correct length that will completely bottom out and provide extra clamping force needed. ARP2000 is capable of achieving clamp loads in the 215,000-220,000 psi range.

Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.
