As a car mechanic, you will often have problems if screws break off faster than expected. Other problems of excessive tightening with a normal wrench can again tempt you to spend on a handcrafted torque wrench. Below is an analyzed article with some basic information. Enjoy using your torque wrench, but be careful with it.
Dropping not only means a loss of dollars, but also a loss of precision and accuracy.
What is a craftsman torque wrench?
Craftsman Torque Wrench is a device with a long shaft and a rotating handle on which the numbers are calibrated. It measures the applied torque and weight. You can read it with different marked scales.
Models by Crafstman Wrench:
- Clicker style
- Bending beam
- Double jet
- Micro Tork
The cantilever torque wrench is calibrated by observing the scale and stopping at the desired number. Once you calibrate it, it can take many years, depending on how long you don't drop it. The design is a little frustrating when you use it at variable angles or deep down. This is because you have to read the scale directly above the needle, which is not very impractical in the above situations.
- Clicker-style micrometers:
When you approach the set torque, you will hear an audible click, indicating that the settings have been made. This type of wrench is far more expensive than the other common ones, but won't let you down due to the longer precision and accuracy of the calibration. Some of them come with variable guarantees, and only a few of them are available with lifetime guarantees.
It's economical, but it doesn't take long to calibrate. It is recommended to use a single project as the reliability of the calibration will be affected more easily and earlier.

Attachments and accessories:
You can replace the accessories and attachments according to your requirements and the desired results:
- Interchangeable head presetting
- Set with narrow insert and ratchet insert
- Interchangeable open ring heads
How to use:
Step 1: The torque fixings are managed after you have cleaned them thoroughly. They are initially tightened to half their potential, as described in their manuals or recommended by the experts. After monitoring the remaining parameters, a final torque screw is carried out.
Step 2: Once you have found the wheel nuts, do not coat them with lubricating, lubricating or anti-seize materials. Start lowering the jack just enough for the tires to touch the road. As already mentioned, first tighten each nut screw to half its capacity. You will reach full capacity once the vehicle is completely shut down.
Step 3: You should lock the torque properly.
Step 4: The correct tightening takes place in a star-shaped order, or you can move clockwise for the 1st, 2nd, 3rd, 4th and 5th nut from 3,7,12,5 and 9 o'clock.
Check that it is correctly calibrated:
- Take a reference length on a piece of paper by marking two ends of the torque from the square drive to the end of the handle.
- You should be very careful when tightening the square drive in the vise. Don't overdo tightening.
- Now enter your measured values in the formula: Product of handle distance and weight divided by 12.
- The weight is freely suspended. Make sure it touches the floor.
- You should now turn the screw clockwise to tighten it. Continue until you hear the click. This indicates that the desired calibration has been achieved.
Applications of the manual torque wrench:
It is used in machines that require a specific tightening of the screws and nuts. It can be used in automotive spare parts, garden tools, the repair of heavy machinery, construction and DIY repairs. It is convenient if you want to get sensitive. However, maintenance may be difficult. You also need to consider many other external factors when calibrating
How to keep it long:
- You should make sure that you clean the threads patiently. They can be rusted or contaminated for a long time by water or other exposures.
- You should never lubricate the parts unless specified by the manual or manufacturer.
- You should make sure that the wrench stays at zero and not below zero as this will lead to errors.
- You shouldn't use it as a breaker bar. This can affect the mechanical function of the torque.
- You should always handle it carefully. Although it is not physically fragile, but its settings are not shockproof, it needs to be recalibrated as soon as it falls on the floor.
- Use it as a special tool.
- You should always pay attention to the upper and lower limits to avoid damage.
- Always keep it in your pocket when you have used it. Keep this case near the ground so that it does not fall when it falls.
- The calibration can be influenced by the temperature. Therefore, keep the device in an environment with controlled temperature.
You can cover a variety of weight ranges. For example, a handcrafted torque wrench can measure 25 to 250 ft-lbs in 0.5 ft-lbs.
- Craftsman Digi-Click torque wrench
- eTork click torque wrench
- Crescent 3/8 ”drive micrometer.
They are usually supplied with a one-year guarantee. If you handle them carefully, they can be used longer without major recalibration. However, some models have a lifetime warranty.
Artisan torque wrench is not an ordinary tool. Not only is it expensive than ordinary wrenches, it also requires great care when holding, handling and manipulating. It is used when tightening nuts, bolts and other fasteners to avoid over tightening. Its application helps improve the life and quality of the machines.
