Overview
|
Anchor nuts are designed for blind mounted applications where it is impractical to use hex nuts or where it is desirable to have an attached nut for ease of maintenance. |
Reviews
These have become way to expensive to purchase if you have another choice. But if you need one this is where you find it.

what I wanted
Look good.
excelent quaity
Works great
The nut-plates arrived quickly, and very well packaged. The quality is second to none!
High quality, a great design, and expensive. In my opinion, worth it for select applications. I used nine of these on a wheel pant installation. Two items: (1) get the right size pop rivets (2) careful with those threads when using. Make sure you get 2 or 3 turns just with your fingers as a start. These are very easy to cross-thread with a machine screw fastener.
Before ordering these, I noted that one reviewer complained about the threads not being very well done. I found that his review was accurate. I do not have a suitable tap to clean out the threads, as that reviewer did, so I just had to lubricate the threads and force a bolt through the nuts several times to make them useable. These are rather expensive items and there should be no excuse for such expensive items being of such poor quality.
