A little info on shear ratings


Shear Capacity Calculation

To roughly calculate the ultimate single shear capacity of a bolt, multiply bolt area at full shank diameter times ultimate shear strength rating, e.g. 8-32 18-8 stainless steel bolt, 0.164" diameter. (A standard 8-32)

Area = πr2; 3.1416 x 0.082" x 0.082" = 0.0211 square inches

Single shear = 90,000 psi x 0.021 = 1890 lbs. at full diameter

This calculation is for shearing a 8-32 on the thread. I am pretty confident it will hold your robot.
