Wing Nuts（Square Wing）

The stainless steel square wing nut (also known as a butterfly nut) is a hand-tightening fastener made of 304 or 316 stainless steel through casting or stamping. It has flat protruding square wing-shaped handles on both sides. Without the need for tools such as a wrench, it can be easily tightened or disassembled with just the fingers. The main body of the nut is usually in a square or hexagonal base shape, with the two wings symmetrically distributed, which combines the convenience of manual operation with the stability after locking.

Product Feature

Manual quick-release, no tools required: The design of the side wings provides excellent grip points, allowing for quick tightening or loosening without tools. It is particularly suitable for occasions that require frequent assembly and disassembly, significantly improving work efficiency.

Stainless steel material, corrosion-resistant and durable: Made of 304 or 316 stainless steel, it has excellent rust and corrosion resistance and can be used in humid, outdoor, and chemical environments for a long time without rusting or getting stuck.

Square base, anti-rotation and stable: The bottom of the nut is usually square or has anti-slip patterns. When in contact with the workpiece, it can effectively prevent the nut from rotating with the bolt, ensuring the stability of the locked connection.

Clean appearance, high recognition: The square wing design is simple and elegant. The stainless steel color or polished finish makes the appearance exquisite, making it easy to identify and operate.
