A click torque wrench is used to apply force onto screws, nuts or bolts when fastening a work piece. The wrench has a click feature that allows you to set the desired torque output. This prevents the wrench from exceeding the preset limit. It is a useful tool for fastening bolts on motorbikes, large equipment and a vehicle’s wheels. Also equally useful is the snap-on torque wrench. It allows you to regulate the torque pressure on fasteners by means of an alarm. A beep signals when desired torque is attained. A comparison of the two types is given below.
Advantages of Click Torque Wrench
Click wrenches provide a virtually foolproof way of fastening for various jobs. Since you can preset the maximum torque level desired, it is difficult for the wrench to over-torque the fastener. The click features allows you to work just as efficiently in confined spaces. You need not strain to ascertain if the wrench has reached desired torque level since it clicks automatically. Click wrenches are more affordable than the snap-on type. Prices range widely for several models on the market. It makes it easier to acquire one.
More effort and time is required when operating the adjustment handle. Work that requires higher torque settings is even more laborious. The click feature can jam while you’re doing a job. This will result in over-torquing, which could easily damage fastener heads. The click torque wrench contains more moving components than the snap-on type. This contributes to a higher wear and tear rate. Frequent lubrication is necessary to keep the various components in good working condition. After each use, you must adjust the setting back to zero. Storing the machine with high readings tends to affect precision in the long run. Click wrenches are also extremely sensitive. If dropped, the impact can easily adjust the spring mechanism. This interferes with accuracy when working. The tool requires its calibration to be checked more frequently than the snap-on type. This adds to maintenance work.
Advantages of Snap-on Torque Wrench
The state-of-the-art design of snap-on wrenches assures both efficiency and productivity in your work. They incorporate a digital display that clearly reflects the desired torque level. A distinct beep is emitted when desired torque is achieved. This signal is more distinguishable from the click sound, which can also be generated by dropping fasteners. You’ll not be misguided by false clicks. The snap-on wrench minimizes confusion when working. Snap-on wrenches incorporate fewer moving components, which creates a higher reliability of the tool. Fewer moving parts require a less frequent maintenance schedule. It also lowers the wear and tear rate of the tool, which adds to its durability. Snap-on wrenches maintain their calibration much longer than the click wrenches. This, too, contributes to them being a lower maintenance tool.
Snap-on wrenches cost much more than the click torque variety. The higher pricing can be a deterrent to acquisition. They also use batteries to power the digital display. If batteries run low while working, you’ll end up with inaccurate readings.
