Bullet 2.0 Metric Guitar Jack Tightener for metric-sized 1mm inch nuts - new version upgraded with brass ferrule for a lifetime of use.

What do you do if your guitar has a loose jack socket? Leave it for later and hope nothing breaks? Take the guitar apart to fix it? The Bullet Jack Tightener works from the outside to prevent twisting and shorting the wires on the inside. Simple and inexpensive, it's a pocket-size fix for loose jacks in guitars and amps. Smooth moulded plastic, so it won't scratch your guitar or amp hardware.

Tighten (or loosen) your guitar's jack in three easy steps: Put the socket head over the 1/2" nut. Press the rubbery Grip-Tip into the jack to hold it. Turn the tightening handle. Easy!

Fits metric-sized 1mm inch nuts for 1/4" inch jacks. Does not fit US 1/2" nuts.

We also have the new Bullet 2.0  with brass ferrule for a lifetime of use with US 1/2" nuts. See separate listing in our EBay shop.
