Nickel-plated brass wing nut in accordance with the DIN 315 standard is a specialized nut that allows easy assembly and disassembly without the use of tools. It has two wing-like projections on the sides that give a good grip for hand tightening. The nickel-plated brass surface provides both aesthetic appeal and extra protection against corrosion. Wing nuts are typically used in applications where quick and easy adjustment or disassembly is needed, such as in electronics, furniture, machines and other equipment.
