Swivel Nut

SKU :

A Swivel Nut is a type of fastener that is designed to allow for angular movement and rotation. It consists of a threaded cylindrical body and a flange that extends out from one end of the body. The flange is typically hexagonal or square in shape, which allows it to be easily tightened or loosened with a wrench.

The key feature of a swivel nut is the ability of the flange to rotate freely around the body of the nut, while the threads remain stationary. This allows the nut to be installed at an angle or in a location where it may be subject to vibration or movement. The swivel action of the nut helps to reduce stress on the bolt or screw it is attached to, and can help to prevent damage to the components being fastened.

Swivel nuts are commonly used in a variety of applications, including automotive and aerospace industries, as well as in construction and industrial settings. They are often used to fasten components that need to be able to move or rotate slightly, such as engines, transmissions, or machinery parts. Swivel nuts can also be used in plumbing and electrical applications, where they can help to prevent leaks and maintain proper alignment of components.


Swivel nuts are designed to allow for greater flexibility in the positioning of pipes, hoses or tubing in a fluid system. They consist of a nut with a specially-designed base that swivels or pivots, allowing for easy installation and alignment of components. The following are some common specifications for swivel nuts:

  • Material: Swivel nuts can be made from a variety of materials including brass, stainless steel, and plastic, depending on the specific application requirements.
  • Size: Swivel nuts come in a range of sizes to fit different pipe or tubing diameters, typically ranging from 1/8 inch to 2 inches.
  • Thread type: The threads on a swivel nut can be either male or female and can be of different types such as NPT (National Pipe Thread) or BSP (British Standard Pipe).
  • Pressure rating: Swivel nuts are rated for the maximum pressure they can withstand without failing. The pressure rating is usually measured in pounds per square inch (psi).
  • Temperature range: The maximum and minimum temperature range that a swivel nut can handle without degrading or failing is an important consideration when choosing a swivel nut for a particular application.

It is important to select the appropriate swivel nut for the specific fluid system in which it will be used, taking into account factors such as the fluid being transported, the operating temperature and pressure, and any environmental or chemical factors that may affect the performance of the swivel nut.
