Structural Shapes Hydraulics Pneumatics Fluids Flow Engineering Threads can be present in the "grip" area between the nut or washer and the bolt head, but cannot be fully engaged at the interface of the two plies that are This website, Roymech, has been an invaluable resource for engineers around the world and we hope to maintain this incredible legacy going forward. Shear ( thread stripping) strengths of screw threads under load are dependent, in addition, on mating component relative material strengths, nut geometry, and coefficient of friction between thread bearing surfaces. n = threads per inch.
