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

Choose between ISO regular metric or fine metric threads and imperial UNC/UNF threads from lots of sizes and materials. Choose also between different friction conditions: lightly oiled, well oiled, etc. Or put in your own friction values.

Calculate the preload forces and stresses also and check the limits for standard materials or for a given yield limit.

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