Breaker Bar
Just like the striking face box wrench, this wrench is useful for loosening stuck bolts and nuts. Instead of force, however, the breaker bar uses large amounts of torque from its very long handle.
By classification, the breaker bar is a socket wrench so typically it is business end has numerous sizes.
Socket Wrench
Socket wrenches’ feature a hollow cylinder which grabs a bolt head or the end of a nut. Usually, socket wrenches also come as ratchet wrenches and it generally has a built-in universal joint that can couple into a number of other socket wrench sizes.
Ratchet Wrench
The ratchet wrench uses a socket but what makes it particularly useful is its one-way mechanism which allows for a continuous motion without removing the socket to turn the wrench again.
So instead, the motion required for turning a bolt or nut is a simpler backward and forwards motion which is of course easier.
Speed Wrench
Features a crank shaped handle driving a socket. Due to the handle, working on a nut or bolt is faster due to the speed it can be turned.
The speed wrench, however, offers less leverage than a ratchet wrench.
Torque Wrench
While its end usually has a socket wrench, the handle of torque wrenches usually has a device that measures torque. This is used in assembling parts of the car that requires precision or a pre-indicated, set amount of torque.
These include working on the cylinder heads, head-studs, camshafts, brakes, and especially crankshafts.
