Default Re: What are these nut things called?

They are known by various names, for instance Nutsert, Hank Bush, Hank nut, Rivet Nut and come in various forms.

Most have to be riveted into the sheet.

Some have serrations to better grip soft materials.

The Clinchnut is pulled into the sheet with a special tool and can be used where there is no access to the rear of the sheet.

There are also self clinching fastners which are simply pushed into the material without the need for special tooling and in extremis can just be fitted with a hammer.
