Black Serrated Flange Nuts made of High quality Stainless Steel also known as a full nuts made of durable A2 stainless steel and to DIN6923 (Serrated flanged Nuts)

BLACKENED FINISH Serrated Flange Nuts – A2 Stainless steel A2 is used in a wide range of applications in different industries such as the automotive industry for body paneling and bumpers etc., food and catering industries for the corrosion resistance, in the engineering and architecture industries, for the remote control and model making.

CHEMICAL BLACK FINISH Serrated Flange Nuts – Benefits of the process include the addition of mild corrosion resistance, improves aesthetic appearance and the minimizing of light reflection. Maximal corrosion resistance can be achieved when the oxide is impregnated with oil or wax.

BLACK FASTENERS MADE OF STAINLESS STEEL – Chemical blackening is often used on fasteners made from stainless steel, copper, copper based alloys and zinc.
