Why can a little nut get the whole car into trouble?

Many people may view a nut as just a small piece, the main price, but in the automotive industry, one nut can be a piece that affects the safety of an entire car, because the nut is not only responsible for holding the parts together, but also for the vibrations, shocks, and tensile forces that occur throughout the life of the car.

If the size of the nut is only slightly inaccurate, whether it is diameter (diameter), threaded distance (Thread Pitch), or the length of the workpiece, it may cause the holding force to fail as designed by the engineer. At first the problem may not be clearly expressed, but when the car is in continuous use under vibration, heat, and real environment, the nut may cause decomposition, wear out faster than usual, or fail to bear the force it should.

For manufacturers, the effect can mean a whole lot of product rejection, a recall, or a loss of confidence from the customer. In the corner of the user of the car, a crash of a critical assembly attachment part can affect the performance of different systems and increase the risk of unexpected damage in the future.

That's why global automotive manufacturers focus on every Fastener, even if it's a small piece, not because it's an important piece, but because they understand that "no piece is small enough to overlook."

If any organization wishes to verify the accuracy of measurement and calibration tools, to enhance production quality, reduce risk of parts dislocation, and prepare for evaluation, various standards can be contacted.
