principle
People who have learned the principles of mechanics generally know. Through the spiral, the spiral movement of the nut into a linear motion along the bolt axis. Tighten and loosen the screw to tighten and remove the coupling.
If we show their helix, the fit between them is actually the fit of the object and the bevel. Objects on the slope of the reason why not fall mainly with their materials (that is, friction) and the angle of the slope and so on. There is a friction angle between the object and the slope, as long as the angle of the slope is less than the object with the slope of the friction angle objects will not slide down from the slope. This is the principle that the nut does not automatically loosen after it is tightened. It is very similar to the slope and so it is very labor-saving, in the helical direction with a very small will be able to get a bolt in the axial force, that is, the workpiece can be tightly linked to the original.
shape
And why is the screw cap to be made hexagonal? Because the honeycomb is a perfect combination of growth and expansion of the structure. The expansion of the honeycomb is the most sophisticated, can withstand the enormous external pressure, to be shared to offset. Bee is the queen as the center, clockwise around the establishment of numerous closely integrated honeycomb. When the workers are nesting, they will be able to complete each room together while the walls of each chamber are shared with the neighbors. Therefore, the most economical materials will not be overweight, and their shapes will naturally form under the action of gravity. The hexagonal, to the construction of the most material and solid structure.
