What I'm sure everyone doesn't know is that we have collaborated with many door and window industries to produce and sell screws. Recently, many friends have asked me why we recommend using SUS410 self tapping screws for doors, windows, and curtain walls instead of other materials like the 200 series and 300 series? Today, the Shanghai Yaluo editor will use our official website platform to explain in detail to everyone.

Because SUS410 martensitic stainless steel can be hardened through heat treatment, while 200 series and 304 series stainless steel cannot.

The main features of SUS410 stainless steel fastener products are:

1. High strength and high hardness: After heat treatment, the surface hardness of the screw is above HV580 (up to HV750), which can quickly complete the fastening process of self drilling and self tapping teeth in one go, greatly saving construction time and improving work efficiency; The mechanical failure torque of screws is 180% of that of austenitic stainless steel SUS304/SUS316 and over 150% of that of ordinary carbon steel; It can drill stainless steel plates below 6mm and iron plates up to 18mm thick, and can be repeatedly drilled multiple times.

2. Excellent flexibility: The hardness of the SUS410 series stainless steel drill tail nail core is controlled between HV350-HV450, and the toughness test shows that it can bend 30 ° -90 ° without fracture (standard 15 °).

3. Super strong salt spray ability: Once SUS410 is corroded, it only retains red rust on the surface and will not penetrate into the interior for corrosion, let alone be rusted and broken like carbon steel. If the rust spots on the surface are wiped off, the surface will combine with oxygen in the air to produce chromium oxide, and it will no longer rust.
