Stainless Steel Self Drilling Roofing Screws

The difference between 304 and 410 stainless steel self-Tapping/ Drilling screws.

The materials are different: 304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm, a high temperature resistance of 800 degrees, good processing performance and high toughness, and is a versatile stainless steel.

410 stainless steel is stainless steel produced in accordance with American ASTM standards, S41000 (American AISL, ASTM). Containing 0.15% carbon and 13% road, it has good corrosion resistance.

The applicability is different: Stainless steel drill tail self-tapping screws 410 can be heat treated, and their corrosion resistance is better than carbon steel, but worse than stainless steel, and can drill through iron plates; stainless steel drill tail self-tapping screws 304 cannot be heat treated, and have strong corrosion resistance and low hardness. , can only drill through aluminum plates, wooden boards, and plastic boards.
