Bullet 2.0 metric guitar jack tightener for 11mm nuts

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 2.0 Metric 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, and a brass socket for a lifetime of heavy use. Tighten (or loosen) your guitar's jack in three easy steps: Put the socket head over the 11mm metric nut. Press the rubbery Grip-Tip into the jack to hold it. Turn the tightening handle. Easy! Fits 11mm metric (most European and Far Eastern) nuts on guitar jack sockets - we have other models for US-sized 1/2" inch nuts.
