Tank bushes are a sealed end Round Rivet Bush that are used to provide a permanent female thread in thin or hard sheet metals without the need for welding. The Round Tank variety features a protruding spigot and a round body.
A hole the same size as the spigot is drilled in the sheet material, and the sheet is placed over the Rivet Bush with the spigot protruding and the underside of the sheet resting on the round body of the bush. The top of the spigot is then “peened” over - worked using either a hammer or a press. This creates a flange which compresses the sheet from the top, forcing it onto the serrations on the top of the round body which then bite into the sheet.
The difference between a Round Hank Bush and a Tank Bush is that the Tank Bush has a sealed end typically used when ingress into products must be prevented. This spigot of the Tank Rivet Bush varies in length depending on the thickness of the material that is being fastened on to.
Tank Rivet Bushes are available in a choice of self-colour, zinc plated or stainless steel.
