Bi-Metal Self Drilling Screw


Drilling Drilldirectly to 0-6mm steel plate.  Different kinds of drill point can be selected according to the application requirement.

Tread Tapping

Heat Treated Portion on Alloy Steel can be easy drilled on the metal plate and form a thread around the hole providing great in-place result.


A2 & A4 Stainless body shank & head can maintain guaranteed corrosion resistance performance.  Thread without deformation helps to maximize the performance of the pulling out and prevent failure of structure from wind pressure.
