The expansion nails has size of M5|M6|M7|M8|M10|M12|M14|M16.
It is also called plastic expansion gecko, plastic expansion rubber granule, plastic expansion wall plug, zhiplastic expansion plug, plastic expansion pipe, plastic expansion screw, plastic expansion bolt, plastic expansion fastener.

Wall entry expanded rubber particles is a kind of plastic fasteners, using PP, PA, PE, material injection molding. The style has fish type wall expansion rubber particles, straight through expansion rubber particles, etc., with coarse teeth self tapping screw.

The material of 067f plastic expansion bolt is made of PE and pp. it is also called self tapping screw expansion pipe, plastic expansion pipe screw, plastic expansion pipe and so on.
We have already talked about the fish shaped plastic expansion pipe. We must make clear the three dimensions of plastic expansion pipe screw: length, outer diameter of drilling hole and inner diameter of exposed surface. Here we will talk about the principle of expansion pipe, we should all understand that when hanging and hanging objects, hardware self tapping screws are stressed, while plastic expansion screws only play the role of cushioning and filling to increase friction!

Assuming that there is no plastic expansion pipe screw, the self tapping screw and the stressed wall panel are hard, and the two hard objects must not be fixed tightly. After adding plastic expansion pipe screws, the two hard objects will have cushioning and gap filling, The load-bearing hardware screw will be very stable!

This is why the diameter of the impact drill should be equal to or slightly smaller than the plastic expansion pipe screw! The purpose is to make the gap fill more tightly and increase the friction force!
