Take benefit from our engineering know how and calculate the max. thightening torque for many iso-metric and imperial screws.

Choose between ISO regular metric or fine metric thread and imperial UNC/UNF thread from lots of sizes and materials. Choose also between different friction conditions: lightly pile, well oiled, guyed, etc. Calculate the preloads and stresses and check the limits.

This app is a "must have" for all engineers, mechanical designers and also for people in workshop.
