How Much Torque Can A Breaker Bar Handle? 150 ft-lbs will break a 3/8″ drive usually and about 300 ft-lbs will break a 1/2″ drive. These are on regular breaker bars that are partially hollow and have the little ball in the space of the head to hold the socket. A SOLID 1/2″ heat treated impact rated drive anvil will go up to about 1200 ft-lbs.
Can you use a breaker bar to tighten? Yes, this is what a breaker bar is for; to give someone more leverage when loosening or tightening a bolt or nut. Although, I would not use a breaker bar to tighten lug nuts as it may cause damage.
Can I use a torque wrench as a breaker bar? Never use your torque wrench as a breaker bar—that’ll damage the torque mechanism. Carry it with kid gloves—a single fall can knock the accuracy off by as much as 30 percent. If you do drop it, get it recalibrated (calibration firms listed below) before using it again.
What is a breaker bar torque wrench? A breaker bar (also known as a power bar) is a long non-ratcheting bar that is used with socket wrench-style sockets. They are used to break loose very tight fasteners because their additional length allows the same amount of force to generate significantly more torque than a standard length socket wrench.

What’s the difference between a torque wrench and a breaker bar?
Yes, the functionality of the breaker bar and a torque wrench is the same. But the difference is that the breaker bar is suitable for loosening tasks, and the torque wrench delivers the best outcome in tightening jobs. It is because torque wrenches have a torque measuring mechanism while breaker bars don’t.
Is breaker bar necessary?
Why do you need a breaker bar
Can you over torque with a torque wrench?
Over-tightening can cause damage to the fastener, and under-tightening can result in making the item you are attaching or assembling structurally weak and potentially unsafe for use. This is true for car parts and for assembling stationary items, as well.
How does a cheater bar work?
When the handle of a pipe wrench, box wrench or ratchet is inserted into a cheater bar, the additional distance makes it possible to generate the required torque with the same amount of force being applied. A cheater bar is sometimes called a snipe, a pipe extension or an extension pipe.
Is a torque wrench really necessary?
If you plan to do any major work on your engine or on some major powertrain components, you absolutely need a torque wrench. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss. Too-tight exhaust manifold bolts can cause the manifold to crack.
What size breaker bar should I get?
The longer the bar is, the higher the leverage and subsequently, the higher the torque. Although length is necessary, there is generally no need to buy the longest break bar you can get your hands on; usually, 16 to 24 inches should be enough for general use.

Can you use a breaker bar to remove lug nuts?
Most breaker bars have a ½-inch or ⅜-inch head to facilitate removing larger nuts, such as lug nuts. That said, smaller sizes can come in handy for removing smaller frozen or heavily corroded nuts.
Can I use an impact wrench to tighten lug nuts?
Once you have tightened the lug nuts to the point that they can’t be tightened anymore by a human hand, you can use the impact wrench. The impact wrench produces a hammering motion to tighten the nuts.
Can impact wrench break bolts?
No, an impact wrench will not break bolts – in fact, it will take less torque to break the wrench’s drive than to loosen the bolts.
How much torque does it take to remove a lug nut?
Car lug nuts are supposed to be torqued to about 100-120 ft lbs, but too often even the pros won’t take out a torque wrench, instead they’ll sow them on with an impact, set a lot higher than 100 ft lbs.
Do breaker bars work?
They are used to break loose very tight fasteners because their additional length allows the same amount of force to generate significantly more torque than a standard length socket wrench. A breaker bar used with socket wrench-style sockets can assist you in taking apart any machine.
Should you double click a torque wrench?
Double checking your torque is never a bad thing.
What should you not do with a torque wrench?
Users should never put a pipe or any other kind of extension onto a torque wrench handle as doing so can seriously damage the tool and make it inaccurate, never mind the potential safety hazard.
Can you use a torque multiplier to loosen bolts?
An electric torque multiplier is controlled with a microprocessor so its torque corresponds to a built-in controller. It’s best suited for continuous tightening and loosening of heavy-duty bolts and fastening applications.
Why are cheater bars dangerous?
Using a cheater bar to tension a dog creates a risk of the bar flicking up and hitting the worker when the tension is released. Others in close proximity are in danger of being hit if the worker loses control of the bar. The tension on the dog varies according to the length of the bar.
