These work as expected. I get zero noise in my headsets with the jacks isolated. Took me a bit to figure out that you need a 7/16 hole for the shoulder to fit through the hole. At first I tried 27/64 drill bit, but that was too small. Next step was 7/16.

The insulated shoulder washer and insulated flat washer combination make it easy to install Switchcraft headset jacks that are electrically insulated from the airframe and therefore more likely to provide clear audio reception and transmission, for pennies (but a lot in shipping, Aircraft Spruce!)

Fit perfectly.

Fit and worked perfectly.

Solved my noise problem while transmitting insulate your Mike jacks

In order to avoid feedback problems (squealing), the Use of this Shoulder Washer is a must if you start using ANR headsets. (No part of the Panel Jacks should make contact with the ground). And... since they were on back order, Aircraft Spruce shipped them to me a few days later without charging me shipping ! Impressive customer service !

Product was delivered as requested .

As ordered and prompt

As always processing and delivery prompt and efficient.

Too expensive

I got em, they work, too expensive

Only went down one notch because the photo does not match the actual washer (a lot). This caused me confusion when ordering. Not sure why I am writing this because I see you have gotten this feedback before (6 months ago) and you have not fixed it. :-)

The picture does not match the shoulder washer. Therefore its not clear that youre ordering the right part.

Way to nickel and dime us to death. Include these with the headset jacks would ya!
