More about us

Frequently asked questions

What types of stainless screws do you manufacture?

We specialize in the production of high-quality SS304, SS305, and SS316 stainless steel screws. Our core product range includes roofing screws, decking screws, and wood screws, engineered for superior durability and corrosion resistance.

Are you a trading company or manufacturer?

StainGrip is a direct manufacturer specialized in stainless steel fasteners. Unlike trading companies, we have full control over the production process, ensuring consistent quality and competitive factory-direct pricing for our global partners.

Do you offer fasteners for B2B and industrial clients?

Yes, we provide comprehensive OEM/ODM services tailored for B2B and industrial clients. This includes customized packaging and head marking to align with your brand identity and technical specifications.

What are the differences between 304, 305, and 316 stainless steel screws?

Grade 304 is for general-purpose corrosion resistance. Grade 305 features a lower work-hardening rate, making it ideal for high-volume decking installations. Grade 316 offers maximum protection in marine or high-chloride environments. StainGrip provides all three grades to match your specific project requirements.

Can StainGrip provide customized head types or coatings for high-corrosion environments?

Absolutely. We offer a variety of head types (such as Torx, Hex, and Square) and can apply specialized anti-corrosion coatings to enhance the lifespan of our fasteners in extreme environmental conditions.

What is the typical lead time for bulk orders to the US or Europe?

For standard stainless steel screws, our lead time is typically 30-45 days. We also offer expedited shipping and flexible logistics solutions for urgent wholesale orders to ensure your project timelines are met.
