Self Drilling Screw

The hex head self-drilling screw is used in the assembly to drill the hole and simultaneously form or cut the thread connected to itself, and the screw itself does not deform and trip.

Self-drilling drill bit, anti-aging EPDM seal, the same colored nut as the color plate.

Self-tapping drill bit: drill bit designed for thick girders; 12.5mm steel boring bar drilled once; drilling, tapping and fixing at one time.

EPDM gasket for self-drilling screws with good physical and chemical resistance.

The Phillips pan head drilling screw is used for non-metal or soft metal without the need for low hole and tapping; the self-drilling screw is pointed so that it can be "self-drilling"; the hole drilled is a hole that does not require tapping. The screws used are different from the general ones. The heads are pointed and the thread are relatively large. They are similar to the chipless tapping. They can be screwed directly without tapping. Metal and plastic usually use this method. The main function of the self-tapping screws is that they do not need to be used with the nuts. In terms of cost, a large number of them are saved. There is no need to cost the nut.
