In the constructor combining good design usually recommend a combination of nuts and bolts using the occasion of merger or a combination of excessive force too much pressure load fault should be broken bolt threads should not be torn. The same concept as the assembly of self-tapping screws. Especially in the case of the stress load. If the merger fails, it should be, instead of thread damage or breakage.
Resistance to thread damage, pull out the function of the shear strength and thread area in other words, the Ministry of screw size, thread length role, thread depth control, thread length equal to the combined effect of overlapping thickness of the workpiece. Theme overlap depth hole diameter from the preparatory decision, another determining factor - screw sizing torque and tensile strength.automatic load sensing power switch
Thickness in any combination, to increase the size of the screw to increase the tensile stress load region, the thread shear stress ratio of the load area, often resulting in tearing or pulling thread, such as reducing the size of the reduction ratio of the screw, but will increase the tightening torque cause screw is broken, so how to balance the tensile strength to resist tearing or pulling the thread size depends on the thickness of the workpiece and use decisions.power load unbalance
