100 DEG CNTRSNK SELF LOCK 12PK
Mounting bracket is very nicely made. As mentioned in previous reviews it did need just a bit of trimming for a flush fit on the altimeter but that’s easily accomplished and took maybe two minutes to mark and cut. Once done, it went together easier than had I used instrument nuts. Nicely packaged. Everything needed is included. Only suggestion to the manufacturers would be to anodize it but not a big deal, just my personal preference

MK-02 INSTRUMENT NUT RING
Perfect for my purpose.
Super easy, perfect fit. A great solution.
Awesome product. There is no way I could have installed my new airspeed indicator in my Ercoupe’s panel without this, there is hardly any room and this plate worked perfectly. Before installing I put a piece of double sided tape in between the insturment and the mount to help hold it in place. Would definitely recommend
Absolutely perfect for my RV9. Purchased with my 2.25 gauges. Installation is a snap. Caution: Some of my gauges were slightly larger than ring ID. No problem - just sanded out a little.
We used these kits on a Decathlon restoration while upgrading the panel. Not only were they extremely easy to use, you end up only spending about $1-$2 more than if you buy long screws and standard instrument nuts. A great value for the giant leap in convenience!
Bought a bunch of these a few years ago thinking they were superior to the older clip in instrument nuts. Naw To make they work right, I had to discard the double stick tape they provide as you destroy those just trying to get them off the sheet, and further remove the backing. Then the nuts themselves are press fit in the frame and if you tighten too much, the nut dislodges and will then spin when you go to remove it. Use duct tape to retain on instrument and a touch of JB Weld to secure the nut is what I ended up doing with each one.
