Drilling Point #5 Self Drilling Screw for 15mm thick metal sheets

more economical installations. The drill point allows these drill screws to be installed into steel base materials

for screw diameters #6 thru 5/16"-18.

Drilling point of the screw : #2, #3,#4, #5 can work on different metal sheets, roofing sheets .

Compared with ordinary Screws, the self drilling screws have higher tenacity and maintenance force, and will not

loosen for a long time after combination. The use, safe drilling and tapping are completed at one time, and the

operation is simple. Thus, whereas a regular machine screw cannot tap its own hole in a metal substrate,
