A4 Stainless Security Fasteners

A4 stainless steel, also known as Type 316, contains approximately 18% chromium and a small addition of molybdenum, providing enhanced corrosion resistance compared to standard stainless grades. Commonly referred to as marine grade stainless steel, A4 is widely used in external, coastal and underwater environments, as well as in specialist applications such as surgical implants.

A4 stainless steel security fasteners offer a reliable solution where tamper resistance and corrosion resistance are both required. We supply a wide range of stainless steel fasteners, including stainless steel security screws and fixings, manufactured in A4 stainless steel.
