Round wing nut is also known as butterfly nut. It is a threaded nut that is placed by two flat projections or wings. These wings protrude from the central part of the nut. The wings also enable the user to tighten them just by using their hands. So the need for an extra tool is eliminated. Mostly, such types of nuts are also used for temporary fastening uses.
The process of tightening a wing nut requires the application of torque. The makers can easily wrap the cloth around the nut to move it in the clockwise and anti-clockwise direction.

Round wing nuts can be made by 4 processes which result in different categorical formations. We can categorize the round nuts into 4 parts;

Type A

This type of round-wing nut is made with a cold-forging process. These are mainly available in regular, heavy, and light dimensional forms.

Type B

This type of nut is used for the hot forging process. These nuts come in three different forms of wings. The wing design determines the application of torque on them.

Type C

These are manufactured with a die-cast process where the wing nuts are made for heavy and regular dimensional series.

Type D

Type D round wing nuts are made with a sheet metal stamping process. The manufacturers sell them in three different wing styles as per the use.

Main features or advantages EMAIL: SALES@AYAFASTENERS.COM

Hand turning application
As the round wing nuts are mainly used for temporary application because they have easy hand application. The hand-turning method of application is convenient for the low torque requirements. There is no requirement for any kind of tools for tightening and loosening such nuts.
Dimensional accuracy
The round-wing nuts are available in four different sizes. Therefore, they come with vast availability in sizes and dimensions. The makers can choose the suitable type as per the application and uses. As a result, round wing nuts provide additional dimensional accuracy.
Strengthened grip
The wing projections of such nuts offer a strengthened grip which provides easy installation.
Corrosion resistance
The composition of such round wing nut mostly contains stainless steel, carbon steel, and alloy steel. This makes them safe from oxidation which protects the material from getting corroded.
Internal threading
The round wing nuts have internal threading which makes them suitable for binding even with lesser torque. Moreover, it helps in engaging with the bolt more properly.

Applications Of Round Wing Nut EMAIL: SALES@AYAFASTENERS.COM

Car batteries
The round wing nut is commonly used in car batteries as they may need frequent reopening. The car batteries also contain an assembly clamp which is used for managing the lid.
Bicycle wheels and Drum kits
For loaded safety spring components, the round wing nut is used which is very common in bicycle wheels and drum kits.
Boat accessories
In boat accessories, the round wing nut is used because of frequent assembly and disassembly. As per the requirement, the threading can be standard or metric.
Assembly clamp
The round wing nut is used for fasteners of lids and assembly clamps.
Gimbal
Here, the round wing nut provides prevention of accidental loosening. The nut is secured tightly without putting much pressure on it. So it provides a very convenient form of opening and closing such items.
