Overview

Precision machined nut ring instrument mounting kit. Designed to slide on from the back side of the instrument using the alignment guide pin inserted trough a screw hole. Pulling on the alignment pin from the front side of the panel allows you to hold the instrument in correct alignment in the panel. Specially designed self-locking pan head black brass mounting screws and nylon washers are the easily installed from the front. Countersunk self-locking black brass scrws are also available. Nut rings can be installed without removing hoses, tubing, or electrical connections. Designed to raplace "grasshopper nuts"!

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

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!
