Auto maintenance on components is very important, if any negligence is likely to cause serious traffic accident. A lot of people think bolt ning tight can assure safety. But actually otherwise, the right way is to tighten the can. Need not tweaked too tight. Used in cars, bolts, nuts connecting fastener many, should guarantee its have enough pre-tightening force, but also cannot twist too tight. If twist it too tightly, on the one hand, will make the fittings in external force produced under the action of permanent deformation, On the other hand will make bolt stretches the permanent deformation, instead of pre-compression decline, even cause slide button or broken phenomenon.
