These screws are made of stainless steel 410, after being heat-treated, much harder and stronger than stainless 300 series screws, the very ideal choice for metal sheet, structure steel etc.
Ruspert plated makes screws have better performance of anti-corrosion, the salt test can reach 500 ~ 1000 hours. Neoprene washer creates a seal that withstands liquid and gas pressure.
The higher the TEK number the larger the drilling point to pierce heavier gauge metals. Different stainless mode for different applications.
