Are the screws screwed in and out with the same force? urgent

Are the screws screwed in and out with the same force? Yu Wenlong, a fastener consultant, thinks that the force of screwing in and screwing out the screw is the same before the workpiece is tightened, or that when the workpiece is empty, the force of screwing in and screwing out the screw is the same. Yu Wenlong, a fastener consultant, believes that the force of screwing in and screwing out the screw is different after screwing in and tightening, because the workpiece has a reaction force, so the force is large when screwing in and small when screwing out.

Yu Wenlong, a fastener consultant, thinks it's best to look up relevant information yourself. Everything I got online was fake. If you don't know how to pretend, you can answer casually. It is simply false or deceptive, which will directly mislead you and even hurt you. The light products are unqualified, and the heavy ones will be fined. Of course, Yu Wenlong, a fastener consultant, thinks that if you have the strength, it is also a good choice to ask relevant consultants to refer to your technology, grasp the development direction of the enterprise, locate products and customers.
