They are commonly used in the automotive industry to remove smaller lug nuts or to do engine work. Because of their medium-sized drive heads, ⅜ breaker bars are typically not too long. For jobs that are in tight space, a breaker bar that is too long will take up too much space and will be unable to be used.At RS, we carry a vast selection of breaker bars in various lengths and sizes, from leading international brands like Bahco and RS PRO.⅜ Breaker Bars Usage⅜ breaker bars are those with a ⅜ inch drive head and are among the most common sizes for a breaker bar drive head. While it is true that the greater the length, the greater the torque, one must be aware that a breaker bar that is too long will be unusable in many situations. Unlike torque wrenches, breaker bars do not require a more professional hand to be used properly - they simply rely on the force the user generates and their longer handles to generate more torque, so they are quite universal tools.Length is the most important facet of a breaker bar and should be one of the key deciding factors for which breaker bar is right for the job. Once the nut or bolt is released, it can continue to be loosened by a socket wrench. By having a longer handle and no ratcheting system, these tools are able to deliver more torque under the same amount of force as one would use on a smaller tool, which aids the removal of seized fasteners. Most breaker bars are made from polished chrome steel, which gives them their strength and their polished finish and also makes them easy to maintain.Breaker bars are significant for their length, which is much longer than a normal spanner or wrench.

They 'break' the seal on stubborn and tight fastenings, which can then be fully loosened by using a ratchet, wrench, or spanner. Breaker bars, however, are used specifically when a fastening is too tight and cannot be undone by a smaller tool, such as a ratchet, wrench, or spanner. Breaker Bars Breaker bars are hand tools used in conjunction with socket wrench-style sockets to loosen fastenings such as nuts & bolts.
