Not Ranked
I totally agree with Rick Parker. When I first built my roadster I used grade 8 1/2" bolts to secure the trailing arms of the rear suspension. I broke the upper front bolts twice and finally decided to use a grade 5 bolt because the grade 8s were so brittle. Three years later and I haven't broken a single grade 5 bolt. There is a world of difference between clamping power and shear strength. The higher the bolt grade, the higher the clamping strength but also the lower the shear strength.
