Self-tapping screws are a type of fastener with a unique feature. They work by tapping their own threads in materials like plastic, wood, and metal.

We offer a range of high-quality stainless steel self-tapping screws in A2 (302) stainless steel and A4 (316) marine-grade stainless steel.

What is the difference between A2 and A4 Grade?

A2 stainless steel is often called 304 grade or 18/8 stainless. The 18/8 is in reference to the amount of chromium and nickel in the material. 18% chromium and 8% nickel. A2 stainless steel is the most common type of stainless steel and is suitable for general use.

A4 stainless steel is often called 316 marine-grade, or 18/10 stainless. As above the 18/10 refers to the chromium and nickel content. 18% chromium and 10% nickel.

A4 stainless steel is usually more expensive as it has a higher tolerance to chemical exposure.
