Rivet Nuts

[roystur44]

Micheal,

Zinc plated steel, knurled, counter sunk head, grip range .020 to .140, open ended


The manual insertion tool is ok but requires practice to get it right. The pneumatic gun is the bomb but costs$$. Amortize the cost over the life of the tool and it's value to the robot.

The nuts come in different thread sizes but we try to standardized all our hardware on the robot. A #10 screw is a good choice for mounting manipulators. 1/4-20 is a little overkill.

FYI if the material is thick enough >.120" you can tap the material. If the thread strips you can drill out the thread and install a Rivnut. If you have alum pop rivets shearing because of load forces a steel rivnut and a screw can be used.

Try them out and see if it works for your application. Don't be discouraged when others say they have problems with using this hardware. It's good to have a understanding of what you can do with these in your Robot toolbox.
