How To Describe The Diameter And Length Of The Socket Head Screw?

The standard type of hexagon socket screw diameter is called the letter "m" + number. The number represents the thread diameter (mm). For example, a screw with a diameter of 5 mm should be called M5, a screw with a diameter of 6 mm should be called an M6, and so on.

Attentions on how to use screws:

Although under normal conditions, the screw will not be damaged naturally, but once there is a problem, it may cause serious consequences such as parts loosening. Correct use habits and daily checks are important:

1. Pay attention to the tightening force of screws

Right people think that the tighter the screw, the better. In fact, screws have their torsion range. If it is lower than this range, it may cause looseness. If it is higher than the range, parts or screws may be damaged. The best way is for technicians to operate in a professional garage with a torque wrench. If there is no such condition, we must pay attention to it. Do not continue to tighten the screw, otherwise it will cause screw thread sliding teeth, resulting in the scrapping of the whole part, or screw the hexagon groove of the screw round, which is not easy to loose.

2. Lock the same plane. If there are more than two screws, one by one is required

Take the stands. Most of the front cover of the bracket is locked by 2-4 screws. When locking four or more screws on the same plane, they should be tightened diagonally one by one. We can't tighten one screw directly at a time. We should tighten them one by one several times. When there are 2-3 screws in the same plane, they must also be locked evenly.

3. Replace damaged and seriously rusted screws and tools in time

Some socket head screws will gradually become round after being loosened / tightened several times or locked excessively. Please replace it in time, otherwise it will be difficult to disassemble or the hexagonal groove will be completely rounded when it is locked. The hexagon wrench can also be used for many times, and it will cause great damage to the screw if it is not replaced in time.

Excessive rust on the strength of the screw will be affected, and it needs to be replaced. If it breaks during use, it may cause danger.
