Stainless steel nuts are a sustainable solution for industrial fasteners. Thanks to their long service life and corrosion resistance, they help reduce replacement frequency and maintenance costs—lowering the total cost of ownership for your projects.
Their high tensile strength ensures excellent load retention, even in dynamic or high-stress environments.
Q1: What’s the difference between A2 and A4 stainless steel nuts?
A: A2 is suitable for general corrosion resistance, while A4 contains molybdenum, offering better resistance in marine or chemical environments.
Q2: Can I request special shapes or coatings?
A: Absolutely. We offer full customization including hexagonal, square, dome, or wing shapes, with optional surface treatments like passivation, zinc plating, or PTFE.
Q3: How do I ensure compatibility with my bolt or thread system?
A: Just share your thread standard or mating component specs—our engineers will recommend the most compatible match.
Q4: What’s your minimum order quantity for custom nuts?
A: We support low MOQ for custom or trial orders, depending on the specifications.
Q5: Do you offer OEM or private labeling?
A: Yes, we support OEM/ODM with packaging and logo customization.
