Forgot to mention...
On the outside of the nutsert there are grooves which are suppose to bite into the metal and to stop it from spinning.
Sometimes the nutsert can spin when you are trying to do the nut up on the bolt which makes me angry...lol
If this happens then you need to stop it from spinning whilst you do the nut up so try doing the following.
- Hold the bolt on an angle to try and force it to lock in to the side of the panel
- Take the nustert and bolt out....Hold the bottom edge of the nutsert with visegrips and do a few rotations to expand the nutsert a little bit and try again...This will make the nutsert a wee bit bigger and should bite in better....You may have to hammer the nutsert back into the hole again too.
