Best Price Quality Machine Custom Non Standard Square Titanium Hot Dip Galvanized Butterfly Bolt For Motorcycle

butterfly bolt and nut, commonly known as a butterfly screw or wing screw, is a type of fastener that features a unique head design and a threaded nut with wing-like projections. These wing projections allow for easy hand-tightening and loosening without the need for additional tools.

Here are some key features and characteristics of butterfly bolts and nuts:

1. Butterfly Bolt: The bolt has a flat, circular head with two or more symmetrical wing-like extensions protruding from the head. These wings provide a larger surface area for easy grip and turning by hand. The other end of the bolt is threaded to engage with a corresponding nut.

2. Butterfly Nut: The nut is threaded internally to match the bolt's thread. It has two or more wings on the outer circumference, corresponding to the wings on the bolt's head. These wings allow for quick and convenient hand-tightening or loosening of the nut.

3. Hand-Tightening: The unique design of butterfly bolts and nuts enables them to be easily tightened or loosened by hand, without requiring any tools. The wings provide a comfortable grip, allowing for quick and efficient installation or removal of the fastener.

4. Materials and Finishes: Butterfly bolts and nuts are available in various materials, including steel, stainless steel, and brass. They can be coated or plated with different finishes, such as zinc plating or chrome plating, to enhance corrosion resistance or provide an aesthetic appearance.

5. Applications: Butterfly bolts and nuts are commonly used in applications where frequent assembly and disassembly are required. They are often found in furniture, equipment, and fixtures that need to be easily adjusted or removed without the use of tools.

It's important to note that while butterfly bolts and nuts offer convenience and ease of use, they may not provide the same level of clamping force or security as traditional bolts and nuts tightened with tools. Therefore, they are typically used in applications where the primary requirement is quick and tool-free installation or adjustment rather than heavy-duty fastening.
