I bought some fasteners to replace my brake rotor bolts on my motorcycle, I need to space out the rotor for some new brakes. The existing bolts were flat head socket screws, 1/4-20, I know none of the other specs for the originals. What I picked up are 1/4-20 flat head socket screws, they are grade 8 alloy steel, the rockwell hardness is c32, they have a 120,000 psi tensile strength, ASME : B18.3 spec. I am unable to find the shear strength. Does anyone on here with more knowledge of steel and fasteners know if I need to be worried about these bolts shearing off. There are 5 of them holding on my front brake rotor, all the load placed on the fasteners will be applied directly to the side. Thanks in advance, Chris
