D = Grout Hole Diameter in inches L = Length in inches of the grout hole = 3.1415 Below are examples of the force required to pull out various size bolts out of various . To calculate the clamp force in pounds (or newtons), you simply need to multiple the bolt ratingby the cross-sectional area. of Horiz. With too little clamping force, the joint may loosen. F = T / K * D. Where F is the clamping force (N, lbs) T is the torque applied to the bolt (N-mm, in-lb) K is the friction of the bolt contact. T = 4,312 in. The force acting in the lubricated bolt can be calculated as Flubricated = (2022 Nm) / (0.2 (0.03 m) (1 - (40%) / (100%))) = 561667 N This is way above what the bolt can handle and fatal failure is likely. If you're using metric bolts, you can calculate the clamping force by multiplying the bolt and nut rating by their cross-sectional areas. These toggles may be adapted to any types of fixtures. force after releasing the load. The Bolt Pattern Force Distribution Calculator allows for applied forces to be distributed over bolts in a pattern. Bolt or Pin Single Shear Stress Applied Force F (N, lbs) = Bolt/Pin Diameter d (mm, in) = Plate Thickness t (mm, in) = Ultimate (Yield Min.) When applied to a bolt, this force becomes tension in the bolt threads, which in turn applies a clamping force (or load) between the two materials you are bolting together. Steel = .2.
