A2 A4 Galvanized Metal Drill Bit Tip Screws 3.5mm X 10mm - 6.3 X
200mm AS DIN7504N
1. Descriptions:
These Pan Head Self Drilling Screws are 100% 304 and 410 Stainless
Steel which is one of the highest forms of corrosion resistant
steel, making it last longer than other hardware on the market
today. The stainless steel is superior to regular steel and
provides excellent rust resistance in water applications. it can be
used both indoor and outdoor.
Standard cross recessed pan head screw, smooth and complete,
stressed uniformly, hard to to skid in the process of
spinning.Precise screw design, the thread can decrease the
resistance when screwing in, prevent cracking. There is no need to
drill a hole first, sharp tail is easy to drill.

3. Applications:
As their name implies, self-drilling screws operate on the same
principles as drill bits and other cutting tools. For any cutting
tool, performance is governed by cutting speed, feed rate, depth of
cut and the work material itself. Then, installation performance of
selfdrilling screws can be linked to the basic cutting tool
parameters where suggested optimal parameter values are listed by
nominal screw size in the table.
When selecting a self-drilling screw, consider the material
thicknesses and types of materials to be joined. Following are some
key design features to look for when selecting suitable fasteners.
