Said on the bolt heads "10-9". Is that a higher grade bolt than an 8? |
According to my McMaster-Carr catalog:
"10.9 steel offers strength comparable to Grade 8." Minimum tensile
strength is 145,000 psi vs 101,000 on the stainless steel.
Rockwell hardness on Stainless is B96-C33
" " on 10.9 is C32-39
