Wing Nut
What is a Wing Nut?

A Wing Nut is a type of internally threaded fastener with two extended “wings” on either side, allowing for manual tightening and loosening without the need for tools. Its ergonomic design makes it ideal for applications requiring frequent adjustments, quick assembly, or temporary fastening. Wing nuts are commonly used in light-duty applications across furniture, equipment panels, fixtures, and consumer goods.
Offering a perfect blend of convenience and reusability, wing nuts are widely preferred in industries where hand operations are essential.

Do you have questions?
What are wing nuts typically used for?
Wing nuts are ideal for applications requiring frequent hand tightening, such as clamps, furniture assemblies, and covers or panels.
Are wing nuts strong enough for structural applications?
They are best suited for light to moderate load applications. For heavy structural needs, standard hex or lock nuts are preferred.
Can I get wing nuts in plastic or stainless steel?
Yes, we supply wing nuts in various materials including nylon (for insulation and corrosion resistance) and stainless steel (for outdoor or marine use).
Do you provide bulk orders for OEM and export needs?
Yes. We cater to both bulk domestic and international orders, including test certificates and export packaging as required.
