Wing Nut

Product Introduction

• Standard Name: Wing Nut (Butterfly Nut).

• Common Names: Butterfly Nut, Wing Nut, Winged Nut.

• Product Definition: A nut featuring protruding ear-shaped flanges (“wings”) on both sides. Its core design enables quick tightening or removal by hand without tools, serving as a convenient fastener for scenarios requiring frequent manual adjustment, rapid locking, or disassembly.

Wing Nut Key Features

• Wing Design: Protruding "wings" on both sides allow for easy manual tightening or loosening by hand,

  tool-free, suitable for frequent adjustments.

• Materials and Coatings: Commonly made of carbon steel, stainless steel, or brass, with zinc plating (ZP),

  natural stainless steel finish, or chrome plating, providing corrosion resistance and aesthetic appeal.

• Strength and Types: Medium strength, commonly forged or stamped, conforming to standards such as

  DIN 315 and ASME B18.6.9.

• Various Sizes: Diameters M4-M24 (or 1/4"-1"), wing shapes include round and square wings.

• Advantages: Easy to operate, quick installation, economical and practical, but limited torque,

  not suitable for high-strength fixation.

Working Principle

• Threaded Fit: The internal thread matches the external thread of the bolt. Axial clamping force is

  generated by rotating the wing by pinching it with your fingers.

• Manual Torque: The wings amplify the leverage force, facilitating the application of sufficient preload

  to secure the component.

• Load Distribution: Evenly distributes tensile force; coatings (such as zinc plating) provide corrosion

  protection.

• Installation Control: Quick hand tightening eliminates tool requirements; the principle involves friction

  and mechanical interlocking.

Product Applications

• Machinery and Fixtures: Secure workbench clamps, molds, or supports for quick adjustments.

• Furniture and DIY: Assemble detachable furniture, lighting fixtures, or trellises with easy manual

  operation.

• Automotive and Bicycles: Secure battery covers, wheels, or accessories for easy on-site maintenance.

• Musical Instruments and Equipment: Secure drum stands, microphone stands, or photography tripods

  for frequent adjustments.

• Gardening and Outdoors: Install fences or sunshades; stainless steel versions are corrosion-resistant.
