M12 Hexagon Serrated Flange Nyloc Nuts Grade 8 A2 Stainless DIN 6923

A2 flange nyloc nuts are used in vibration-prone environments and in applications requiring corrosion resistance, such as the automotive, aerospace, and general engineering industries. They are also popular for DIY projects where a secure, corrosion-resistant fastening is needed. The built-in flange distributes pressure and can cover uneven surfaces, while the nylon insert locks the nut against loosening.
