Written by Ryan Gilmore Updated: 7 March 2024

Of all the necessary tools you’ll need to work on a car, the ones that deal with nuts and bolts will be the most common you’ll use. You may be aware that nuts and bolts often require torquing to a specific degree on cars to ensure they remain attached.

An incorrectly fastened nut or bolt could potentially come loose if you’re not careful which poses a safety risk. The most common you’ll probably come across is wheel nuts, which hold the wheels on and we don’t really have to tell you about the importance of keeping wheels attached to a car.

One downside to these tightened fasteners is that they can be a real pain to loosen. A quick blast with an impact wrench makes it effortless, but they’re expensive tools and not the first thing you’ll have in the event of a breakdown. Breaker bars are the perfect tool for loosening tough nuts, they’re simple to use and really strong, and best of all, they don’t cost a fortune. We’ve chosen our favourite examples below for easy wrenching.

The best breaker bar

An excellent choice for loosening tight fasteners, this breaker bar from MAXPOWER gets our top choice because of its solid construction and reasonable price. Made from Chrome Vanadium Steel, it’s a tough option and should hold up well against rusting or corrosion.

The socket head can be rotated by 270° and supports the typical 1/2 Inch Dq. Drive which means most socket sets will fit. Like most socket holders, it features a spring-loaded ball bearing mechanism to hold the socket securely in place too.

Pros

  • Solid construction
  • Great socket head adjustability

Cons

  • Handle isn’t the most comfortable
Length 600mm
Material Chrome Vanadium Steel

The best breaker bar on a budget

Price: $40.82
Ideal if you’re on a budget, this option from Rolson gets the basics perfect. Made from Chrome Vanadium Steel and featuring a flexible 1/2″ Sq. Drive head, the bar will be able to tackle the same jobs as the MAXPOWER option above.

It may not have the perfectly polished finish or stylish design touches of the other options, but when you’re knee-deep in oil at the side of the road in the rain I doubt you’ll care that much. A more serious however is the shorter handle, meaning shifting nuts and bolts will be more reliant upon your muscles.

Pros

  • Well-made
  • Affordable

Cons

  • Shorter arm than other options
Length 450mm
Material Chrome Vanadium Steel

The best breaker bar for tough jobs

Price: $37.08
Designed for dealing with vans, this breaker bar from Draper is manufactured to rigorous standards and is branded Expert Quality. The largest option here with a 640mm handle length, it’s a really tough tool and should be easily capable of dealing with any automotive task you can throw at it.

Pros

  • Longest product in this list
  • Designed for vans
  • Manufactured to high standards

Cons

  • Hard to store
Length 640mm
Material Chrome Vanadium Steel

The best extendable breaker bar

Price: $71.58
While a longer breaker bar will make wrenching bolts easier, they’re not the easiest thing in the world to store. After all, who has a toolbox that’s over 600mm long? Sealey has you covered though with an extendable breaker bar. At its smallest, it’s 450mm and can extend to 600m while still being strong enough to tackle tight fasteners. It also has a soft handle for better grip and comfort.

Pros

  • Easy to store while still being strong
  • Comfortable handle

Cons

  • Expensive

What is a breaker bar?

A breaker bar is like any other wrench but is entirely solid in its construction, there is no ratcheting mechanism which means breaker bars are capable of reaching higher levels of torque and loosening really tight bolts. Known for having a longer handle than other wrenches, this design allows for the maximum amount of torque to be drawn from the operator.

You can get even more torque with a cheater bar, a pipe slid onto the end to offer extra purchase and extend the arm of the wrench. These won’t really be required for automotive tasks, they’ll be mostly reserved for industrial use or loosening cross-threaded bolts.
