Any tool that can be utilized to tighten a bolt or nut to a certain torque is popularly known as a torque wrench. These tools are vital socket wrenches, but with extra parts that allow the measurement of torque. When putting it simply, torque is the amount of rotational force that causes the rotation. Typically, it is measured in foot-pound increments. Torque wrenches are most frequently utilized for tightening the bolts of the car wheels but have several additional purposes. These are nine different kinds of torque wrenches and each of them has its own benefits and disadvantages.
Click Torque Wrench
It is the most common kind of torque wrench and is available in almost all the places. A click torque wrench makes use of a clutch mechanism that is calibrated for measuring the foot-pound increments accurately. One of the most common types of clutch used in a click wrench uses a ball and a spring detent. When the spring detects that the required amount of force has been used, can release itself and force the ball detent out of the place, which causes a clicking noise.
This kind of torque wrench has a great precision than several other torque wrenches that are available in the market. It also has the benefit of offering an auditory clue, as resisted to a visual one which may be missed by a mechanic.
Beam Torque Wrench
It is the most basic form of torque wrenches. It makes use of two beams for calculating and indicating the amount of torque that has been applied. One of the beams can move in a freeway at one end, which permits it to show, on a printed scale joined to the wrench, the amount of torque that has been utilized.
Slipper Torque Wrench
In a slipper torque wrench, a cam and a ball can do all the measuring things. The roller exerts force on the cam and looks it in place when enough force has been applied. If the operator tries to add more force, the cam can slip, thus not applying any additional torque.
Deflecting Beam Torque Wrench
This torque wrench makes use of a deflecting beam rather than spring for detecting torque. This results in a tool that does not require to be calibrated as frequently. Generally, it also has great durability when compared to other kinds of torque wrenches. Its general operation is the same as typical beam torque wrench; the only dissimilarity between the two is the way that the deflecting beam wrench reacts to the relative displacement.
Hubless Torque Wrench
Hubless torque wrenches are not the ones used on the cars. They are used by plumbers for tightening the pipe couplings. Generally, they look like a T- handle wrench, and utilizes a ratchet and a clutch. You cannot adjust this torque on torque wrenches that come without a hub, they are pre-set so that they can tighten up the couplings without causing any damage to them.
