Round Head Self Tapping Screw With Cutting

The Round Head Self Tapping Screw With Cutting by Dazhe supplier is one of the threaded fasteners tapping out the matching threads during pre-drilling of metal or non-metal materials.

Self tapping screws are used to connect thin metal plate. When connecting, first make the threaded bottom hole of the connected piece, and then screw the tapping screw into the threaded bottom hole of the connected piece. Round head tapping screws are suitable for situations where drill bits are allowed to be exposed. When installing and disassembling, cross groove tapping screws need a cross wrench.

Materials & Surface Treatments

1.Materials

We mainly use two types of materials. First is stainless steel (like grades A2 and A4) — it has excellent corrosion resistance, perfect for applications where rust prevention is a top priority. The other option is carbon steel, which is more cost-effective. We can add a galvanized coating to boost its corrosion resistance too.

2.Surface Treatments

To make the screws more rust-resistant and visually appealing, we usually apply treatments like galvanizing, nickel plating, or phosphating.
