There’s a moment you reach trying to get a bolt loose when you say to yourself, “Just a little more torque should do it.” Then, inevitably, the bolt snaps the head off and you’re left with half the bolt still threaded and the other piece in your hands. Not good, but it is fixable!

Removing a broken bolt has the privilege of presenting as an immediate pain in the hiney. It sets you back, and you’re then stuck with removing it. But with a few key tricks of the trade that Car Autance’ editors have picked up over the years, we’ll get your project back on track and reduce your input into your family’s swear jar.

The Safety Brief

We want for you to exit the garage with all the fingers you went in with. There’s no need for safety to come third, make it first. To ensure your skin stays unblemished and your bones intact, you’ll want a good pair of mechanics gloves and safety glasses. Let’s start with the basics.

The Tools & Parts You Need

A trip to the auto parts store or waiting on your porch for Amazon can be a time-suck. Don’t spend the day twiddling your thumbs waiting for a package or driving to and from the store. Get everything the first time, such as a tap set, torque wrench, breaker bar, blowtorch, and penetrating fluid.

The How-To

Time to remove that broken bolt. There are a few methods of doing so, but tapping the broken bolt is really the only surefire way every single time, so we’re going to focus on that method.

As with removing a stripped bolt, you should also always start by applying a light amount of penetrating fluid to loosen the bolt threads—you can also use a blowtorch to loosen up the bolt.

  • 1. Make a Small Indentation Into the Middle of the Bolt.

This provides a point to set your tap set drill bit into.

  • 2. Using the Tap Set.

Drill into the bolt with the reverse-turn tap (this ensures that the bolt doesn’t tighten when drilling). Go deep enough to insert one of the tap set’s extraction bits.

  • 3. Switch to an Extraction Bit.

Hit the extraction bit into the pilot hole,and remove the bolt using the drill’s reverse.
