1 The shear tests were conducted with SAE Grade 5 bolts with minimum yield strength of 85 ksi and minimum tension strength of 120 ksi . Shear testing for the 1 / 4-in . models were conducted with SAE Grade 8 bolts with minimum yield strength of 120 ksi and minimum tension strength of 150 ksi in 6,000 psi concrete . High-strength bolts were used to force concrete failure modes . When using steel bolts with a lower tensile strength , steel failure must be considered .
