A lot of people concentrate only on the factory calibration for their torque wrenches. However, while proper calibration is vital, the technique of the operator has a larger impact on the tools’ accuracy. In terms of torque tools, the equipment should not be the limiting factor.
It is vital to use the kind of torque wrench that is that tells you how much force you want to apply to fasteners to avoid over- or under-tightening. Often, a torque wrench has a gauge that indicates the amount of torque applied in the activity to make sure the nut or bolt isn’t over or under torqued. Manufacturers of torque wrench design their products for various applications for both industrial and automotive use. Keep reading to know the different kinds of torque wrenches:
Deflecting Beam Torque Wrench
This torque wrench applies torque to a deflecting beam instead of a coil spring that extends the wrench’s life and ensures optimal accuracy. It comes with a simple design with proven dependability and results. It maintains its accuracy over the long term because it doesn’t have wearing parts.
Micrometer Torque Wrench
In this torque wrench, the torque setting is adjusted by twisting the handle until the correct setting on the tool’s barrel is reached. When the handle is rotated clockwise, a spring inside will be tightened. When applying torque to a nut or bolt, the wrench clicks to indicate the correct torque has been reached. A micrometer torque wrench’s automatic reset features make sure that the wrench will automatically reset itself after use by taking away the load on the spring. It comes with a sturdy and robust design which makes it ideal for daily use.
Dial Type Torque Wrench
This is the only kind of torque wrench where the hand-hold position on the wrench does not affect the final reading. Because it is wider than other kinds of wrenches, it can be hard to use in tight situations. Also, the dial scale needs to be always in sight to identity the torque being applied. This is the type of wrench commonly used in the automotive, aerospace, and defense industries.
Electronic / Digital Readout Torque Wrench
This wrench comes with a digital readout screen that lets users program the torque limit. Its strain gauge sends a signal to a transducer to determine the torque’s force per unit. Over the last few years, this wrench has become more affordable and accessible for the majority of automotive mechanics.
