The torque required to lift or lower a load can be calculated by "unwrapping" one revolution of a thread. This is most easily described for a square or buttress thread as the thread angle is 0 and has no bearing on the calculations. The unwrapped thread forms a right angle triangle where the base is long and the height is the lead (pictured to the right). The force of the load is directed down… WebContact Nook Industries if you’re looking for precision acme screws and lead screws. We provide precision inch acme screw and metric acme screw products.
