Hexagon Head Self Drilling Screw

Characteristics and applications of hexagon head self drilling screws

1.Hexagon head self drilling screws is a kind of screw with drill bit. It is constructed by special electric tools.Drilling,tapping,fixing and locking are completed at one time.Self drilling and self tapping screws are mainly used for the connection and fixation of some thin plate parts,such as the connection between color steel plates and color steel plates,the connection between color steel plates and purlins,wall beams,etc.their penetration capacity is generally not more than 6mm,and not more than 12mm.

2.Hexagon head self drilling screws are often exposed outdoors and have strong corrosion resistance;The rubber sealing ring can ensure that the screw is impermeable and has good corrosion resistance.

3.Hexagon head self drilling screws are also suitable for wood materials,which are generally operated manually.

4.Hexagon head self drilling screws is the combination of tap and bolt.The front is a tap and the back is a thread.On general soft materials, drill a hole and screw it in directly.The thread is tapped out by the tap,and then the bolt thread is strong.If the screw diameter is small,the material is soft.You may not even need to punch holes first, such as screwing into wood.

5.Hexagon head self drilling screws are usually described by three parameters: screw diameter series,number of threads per inch length and screw length.There are 10 and 12 levels of screw diameters,and the corresponding screw diameters are 4.87mm and 5.43mm respectively;There are 14,16 and 24 threads per inch length.The more threads per inch length,the stronger the self drilling ability.

The process is controlled layer by layer,and everyone pays attention to quality.
