What is the difference between 18-8 and metric screws?
More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They may be mildly magnetic. More corrosion resistant than 18-8 stainless steel screws, these metric screws have excellent resistance to chemicals and salt water.
What is the strength of A286 screws?
A286 stainless steel screws have comparable strength to alloy steel with the corrosion resistance of 18-8 stainless steel. With a tamper-resistant Torx or Torx Plus drive (also known as a pin-in Torx or Torx Plus drive), these screws are difficult to remove without special tools.
