Jack Hack Headphone Jack Avionics Tool

Add to Wishlist
Part# 11-18305


The “Jack Hack Avionics Tool” is used to prevent headphone jacks from spinning while you tighten the nut—conveniently without the need to reach behind the panel to hold the back side.

This a “must have” tool set for avionics and radio technicians. It has the potential to pay for itself on those jobs that you would otherwise spend half a day pulling the panel just to tighten the jack.

The Jack Hack includes two expanding post tools: one for standard 0.25 (¼ inch) diameter jack used for stereo GA headphones and one for the smaller (0.205 inch) jack used for the PTT connection.


  • Set includes a wood block tool holder with a magnet and a 7/64 hex key.
  • Material: 7075 Aluminum
  • Finish: Conversion coating
  • Tool label: permanent laser mark

We have this tool in our shop and I am buying one to have in my toolbox. It has saved me from pulling the sidewall many times. It always comes through and is a huge time saver.

Great idea well manufactured works well and comes with its own keeper in which to store the tool. An elegant (albeit a bit expensive) solution to a problem I have every time I attempt to tighten a headphone jack.

Excellent tool. Would suggest changing to a ball end allen key to facilitate access when a 90 degree approach to the installed tool is obstructed.

Handy tool for tightening headphone and mic jacks without needing behind-panel access. Works with both 0.250 and 0.206 jacks. Handy storage block included.

I love this Jack Hack. Best little tool for my panel installation. Really saves on contortionist moves to get to the back of the panel to hold the jacks so I can tighten the jack nuts. This makes it soooooooo easy!

This is one of the coolest tools I’ve seen in a while, this tool can potentially save you hours of trying to reach the backside of a phone jack to tighten without twisting the wires off.

Works as advertised. I wish the shaft was a little longer to allow more room between the handle and the panel. It was difficult to work around the handle to tighten the nut.

Q: Will the 0.250 (1/4) work on the Mono military style headset/helmet jack?

No. The 0.25 (1/4 inch) diameter tool is for GA stereo headphone.

Q: I dont understand how this tool works? The pictures dont help me. Insert in jack, tighten with set screw, expands the tool to grip the jack from the inside? Then tighten mounting ring?

Yes that is how this tool works.
