High Corrosion Resistant Screws, Bolts & Washers

Rust Proof Screws

What are corrosion resistant screws?

Corrosion resistant screws, also known as rust proof, non-rust, or anti-rust screws, are engineered to maintain strength and integrity even when exposed to moisture, chemicals, or saltwater environments. They’re ideal for applications in marine, chemical, and industrial sectors where long-term reliability is critical.

What materials are available?

We supply rust proof screws and fasteners manufactured from a range of highly corrosion-resistant materials, including:

• Duplex Stainless Steel – High strength with superior resistance to pitting and stress corrosion.
• A5 Steel – Durable and ideal for demanding outdoor applications.
  1.4529 HCR (Grade A8) Steel – Premium-grade alloy for extreme environments.
• Super Duplex Stainless Steel – Available for applications requiring maximum corrosion protection and higher mechanical strength.

We also provide corrosion-resistant options in Aluminium and specialist alloys such as Waspaloy.

Many of our rust resistant screws and fixings are available from stock, while others can be custom manufactured to your specifications, including non-standard sizes, metric or imperial threads, and special finishes. All are supplied with short lead times.
