About Mini Rivet Bushes

Mini Rivet Bushes provide strong reusable threads in panels too thin to be conventionally tapped.

 

They can be installed into panels as thin as 0.5mm and do not suffer from the maximum hardness limitations of Self Clinching Nuts and Standoffs so are suitable for installation into Stainless Steel panels.

 

The mini pattern provides excellent resistance to torque and are available in Steel and Stainless Steel as standard with Aluminium and Brass available to order.

 

We can supply Mini Rivet Bushes to suit a range of panel thicknesses and can supply parts to non-standard dimensions and hole sizes to suit your specific application.

 

deally Mini Rivet Bushes should be installed using a press with a suitability profiled punch to optimally swage the spigot, however they can be installed using a hammer and ball bearing.
