The difference between combination screws and ordinary screws

(1)The difference in appearance: this is the most obvious difference between the two, the combination screw is equipped with a spring pad or flat pad than the ordinary screw, or the spring flat pad, and the screws are installed before the rolling teeth, and the washer can not be removed after the rolling teeth.

(2) The difference in mechanical properties: the combination screw needs three assemblies to work together, the flat pad is matched, the flat pad will not fall off, and the fastening has become the assembly, so the fastening effect is better, and the mechanical properties are more solid than ordinary screws.

(3) The difference in use: the use of ordinary screws is more extensive than the use of combination screws, basically industrial products will use ordinary screws.
