More information about threaded bushes

What exactly is a threaded bush?

A threaded bush is a solid, round piece of metal with a smooth outer surface. The inside consists of a threaded hole. A threaded bush is also called a connecting nut (although these normally have the hexagonal shape of a nut). Threaded bushes are also referred to as weld-on bushings or weld-on nuts.

Threaded bushes are similar to welding sockets (also known as weldolets). You can think of both as a piece of pipe threaded on the inside. However, the difference is that a threaded bush has a larger wall thickness compared to a welding socket.

Thread inserts (with external threads) are called threaded bushes by some companies. This can cause confusion.

Application of threaded bushes

Rob Snel mostly uses threaded bushes to attach door hinges to a frame. This involves adjusting the eye bolt to the correct height where the door rubber is sufficiently compressed. The nut is then tightened so that the eye bolt remains stable in its position.
