Spring Nuts

A spring nut, also known as a cage nut or captive nut, is a type of fastener designed to provide a threaded anchor point in a thin or limited-access material, such as sheet metal, panels, or other thin materials. It is often used in applications where a standard threaded nut cannot be easily used due to the material's thickness or configuration.

Spring nuts are commonly used in applications where traditional nuts cannot be easily used, such as:

  • Sheet Metal Assembly: Spring nuts are often used in sheet metal fabrication and assembly to create threaded connections without requiring access to the backside of the material.

  • Panels and Enclosures: They are used in panels, enclosures, and cabinets to provide adjustable and removable threaded anchor points for components and equipment.

  • Equipment Mounting: Spring nuts can be used to mount equipment, racks, and accessories to rails or other structural elements.

  • Automotive and Electronics: They are used in automotive applications, electronics assembly, and various industrial contexts.

Spring nuts are especially useful when a threaded connection needs to be established on a material that is too thin to support a traditional nut or where access to the backside of the material is limited. The spring-like action of the tabs or springs provides a reliable grip and prevents the nut from loosening. As with any fastener, proper installation techniques should be followed to ensure a secure and reliable connection.
