Unthreaded fasteners are available in both inch and metric measurements. These fasteners are typically used to provide spacing or stacking for circuit boards or paneling, and they are often installed over the top of screws. Spacers can be stacked if necessary to cover longer screws.

Since unthreaded fasteners are not threaded themselves and are placed over the screw, there is no torque involved in their application. This means that the spacer can spin or twist freely without impacting the functionality or integrity of the application in which they are used. Their primary purpose is to maintain the desired distance or separation between components, ensuring proper alignment and spacing without the need for threaded engagement.
