Carbon steel wing nuts / butterfly nuts Din 315

Wing nuts from ITA Fasteners come with two flat and wide protrusions which make it easy for frequent adjustments which have to be made by hand. They are commonly adjusted without the help of tools, and for that reason, they are one of the most popular fasteners used for home improvements. They also have sharp aesthetics which make them visually appealing for customers. In its crux, this fastener can be used in applications like machine adjustment knobs where easy and quick access is required. Please note that these nuts are not suitable to be used in applications which have to withstand many vibrations. This can severely damage the surface onto which it has been fastened and also loosen the nut from its position. Therefore, it is crucial that its vibration handling capacity is thoroughly studied and then used if it is being used in high maintenance and critical applications. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
