What are Rivet Bushes?
Rivet Bushes are also commonly called Hank Bushes and come in many types: from m6 Hank Bushes to Anchor Rivet Bushes. They have a protruding spigot and are used to provide a permanent female thread in thin or hard sheet metals without the need for welding.
How to use Rivet Bushes:
A hole the same size as the spigot is drilled in the sheet material and is then placed over the rivet bush with the spigot protruding and the underside of the sheet resting on either the hexagon or round body of the bush. The top of the spigot is then “peened” overworked using either a hammer or a press. This creates a flange that compresses the sheet from the top, forcing it onto the points on the top of the hexagon or round body which then bites into the sheet.
This spigot of the Hank Rivet Bush varies in length depending on the thickness of the material that is being fastened on to.
