Micro Fasteners Screws Used on the plastic, Pay Attention To The 7 Points

There are many places to pay attention to the micro fasteners screws used on the plastic plate. Firstly, this screw is made of metal material. The material of the plastic plate is different, and the density of the two is different.

Plastic board on the use of micro fasteners screws general force is small, thread type is best to consider tapping, tapping screw type is advantageous to the thread, not easy to loose, the determination of the tightening torque and the corresponding bottom hole diameter should be through the use of environmental simulation to get, and not easily to decide according to the data, otherwise it will cause serious consequences. The micro fasteners screws used on the plastic plate should be paid attention to prevent screw sliding thread. There are several main reasons for screw sliding thread on the plastic plate.

★Shrinkage depression of inner wall of bottom hole.

★Material problem of plastic parts.

★Too much tightening.

★Improper use of tools.

★Too many times of screw removal and assembly.

★Too few effective threads.

★The bottom hole size is too large.

All the above are the reasons causing the micro fasteners screws to slip on the screw plate. Especially in the installation of this step, the strength of the difference can also lead to plastic cracking. So that’s all we need to know about the micro fasteners screws that are used on the plastic sheet, and hopefully that will help you.
