Butterfly Screw

A butterfly screw, also known as a wing screw or thumb screw, is a type of fastener that features two large, wing-like projections on its head, allowing for easy manual turning without the need for tools. This design facilitates quick and frequent adjustments, making butterfly screws particularly useful in applications where components need to be assembled or adjusted often and easily.

Butterfly Screw Key Features


  • Ease of Use: The prominent wings provide a secure grip for tightening or loosening the screw by hand, ideal for quick changes or adjustments.

  • Material: Typically made from metals like stainless steel, brass, or plastic, depending on the required strength and resistance to corrosion.

  • Design Variability: Butterfly screws come in various sizes and thread patterns to suit different materials and thicknesses.
