Precautions for the quality of the combined screws.
First, the surface of the combined screw should look at the presence or absence of burrs, or scratches. There is no oil, or rust. To check the material of the combination screw, use the grade strength that should be consistent with the different high strength.
Second, the combination of the screw and the nut should be different from the grade of the nut.
Third, when installing and using the combination screw, it should not work in the rain under reasonable weather conditions.
Fourth, when installing, the over-disabling force is excessive and the force is too large. Causes slipping or locking.
