Wing Nuts

A wing nut (butterfly nut) is a fastener with an internal metric thread.

It is a round, conical part with two flat ears (wings) positioned in a vertical plane.

The wings are designed for hand tightening, without the use of a wrench.

Wing nuts are made from various materials, both coated and uncoated:

• carbon steel;
• steel with corrosion protection provided by zinc plating, chrome plating, or nickel plating;
• stainless steel;
• malleable cast iron;
• brass, aluminium alloy.

Scope of application

A wing nut is convenient for mounting structures that are assembled and disassembled frequently. The fastener is used in threaded connections together with bolts, studs, screws and washers with matching dimensional parameters.
