Breaker Bars And Torque Wrenches Available here. Breaker bars and torque wrenches are similar looking tools that do different things. A breaker bar kind of looks like a long ratchet and is used to loosen very tight nuts and bolts. The length of the breaker bar allows you to create greater torque than you could with a regular socket spanner. The longer the bar, the more torque you can apply. A common use for breaker bars is to help you loosen wheel nuts or hub nuts. Torque wrenches are a different kind of tool that is used when you need to apply a precise amount of torque to the nut or bolt. Sparkplugs, wheel nuts and the bolts used to secure gaskets are examples of places you’d use torque wrench. We have both breaker bars and torque wrenches in stock.
