FAQ
Q: What makes 316 stainless steel better than 304 for marine?
A: 316 contains molybdenum, which provides better resistance to pitting from chlorides (like saltwater), making it more suitable for marine environments.
Q: What sizes are available for marine screws?
A: Sizes range from M2 to M8 with lengths from 6mm to 100mm.
Q: Can I get screws with Dacromet coating?
A: Yes, Dacromet coating is one of our surface treatment options.
Q: Are these screws compliant with international standards?
A: Yes, we manufacture to ISO, DIN, ASTM, ASME, ANSI, and JIS standards.
Q: What strength grades are available?
A: A2-70, A2-50, A4-70, and A4-50 are available.
Q: Can you provide OEM packaging?
A: Yes, we offer OEM services including packaging.
Q: Do these screws have good anti-fatigue properties?
A: Yes, they are designed with high tensile and anti-fatigue properties.
