Force is calculated consistent with units used. Note: This calculator initially assumes dry and perfect threads made from steel and/or zinc plated. There are at least three types of power screw threads: the square thread, the Acme thread, and the buttress thread. Of these, the square and buttress threads are the most efficient. That is, they require the least torque to move a D. T = DFK. This formula expresses the relationship between the load in a bolt and applied torque. The "D" represents the bolt's diameter, the "F" is the axial bolt force, and the "K" represents "k-factor" or "nut factor" which is a variable based on the use or absence of lubrication. The k-factor for a non-lubricated joint. In the case of screw conveyors, horsepower is the power needed for the machine to safely transport a bulk material a fixed distance. 2.
