Wrenches, utilizing the principle of leverage to apply torque, are commonly used to tighten or loosen bolts and nuts. They can be divided into the following categories:
- Open-end Wrench: The opening size of an open-end wrench is usually fixed at 90 degrees to fit a hexagonal or square nut. In addition, an open-end wrench of the same size can only function on a nut of the same size.
- Adjustable Wrench: Different from the open-end wrench, it can adjust width to fit the diverse specifications of the nut. However, it may be slippery during use and less reliable than an open-end wrench.
- Hex Wrench: With a hexagonal jaw, it can be perfectly applicable to hexagonal screws. Due to a larger contact surface with screws, it can easily apply torque.
- Socket Wrench: Consisting of a socket and handle, using the socket to sleeve the nut and then gripping the handle to rotate the socket. Its advantages are more pronounced in confined spaces or when screws are in a deeper location.
- T-Handle Preset Torque Wrench: The biggest difference with other wrenches is you can preset a torque value, and the wrench will remind you when the torque reaches the preset value in sound or vibration.
Now, we have arrived at the main part of this blog, introducing the T-Handle Preset Torque Wrench in its uses, features, and comparison with other wrenches.
What is T-Handle Preset Torque Wrench?
Essentially, a T-handle preset torque wrench also works to tighten or loosen bolts and nuts. Differing from other wrenches, workers can precisely control the applied torque because of the built-in spring and torque sensing mechanism.
When users apply rotational force to the wrench, the internal structure will convert this force into torque. Once it reaches the preset torque, the wrench will remind the users by making a clicking sound, generating vibration or resistance, etc.
Usually, T-handle preset torque wrenches are pre-calibrated to a specific torque value, so you don't need to adjust it again. And it will be more accurate without error when setting the torque value.
Uses
Due to its high precision, T-handle preset torque wrenches can be used in precision machining, like machinery manufacturing and assembly, electronic equipment manufacturing, and other fields.
In machinery manufacturing and assembly, the assembly of various mechanical equipment requires an amount of bolts and nuts for connection. A T-handle preset torque wrench can ensure every fastener is precisely tightened to the standard torque, as far as possible to ensure the equipment assembly effect.
In electronic equipment manufacturing, the connection of some small components in electronic equipment also requires precise torque control. A T-handle preset torque wrench can ensure the bolts and nuts are tightened to the required level without damaging any electronic components, guaranteeing the electronic equipment operates properly.
Compare With Other Wrenches
Due to the special design of the T-handle preset torque wrench, there are some differences between it and ordinary wrenches in terms of precision, scope of application, price, etc. Now, we will make an all-around comparison between the T-handle preset torque wrench and ordinary wrenches.
- Precision: Users can only judge the size of the applied force of ordinary wrenches by their feeling and experience, and no precision is available; while the precision of a T-handle preset torque wrench can achieve plus or minus 10% torque, which can prevent damaging the workpiece from overexert or avoid safety hazards because of the weak connection by under-exertion.
- Application: Ordinary wrenches are commonly used in simple maintenance and assembly work in our daily lives. In contrast, the T-handle preset torque wrench is widely used in machinery and other high-precision fields.
- Adaptation: Ordinary wrenches consist of the handle part and the end part combining to an undetachable whole, and it is necessary to prepare a large number of matching wrenches when encountering screws with various shapes and sizes. The head of the T-handle preset torque wrench is removable, so you only need to prepare different replaceable heads which can save space.
- Efficiency: T-handle preset torque wrench can quickly and accurately tighten screws, saving the time to repeatedly adjust and inspect at a later stage, especially when you need to handle lots of workpieces.
- Durability: The precision parts inside the T-handle preset torque wrench are more susceptible to damage by external impacts, falls, and other factors than ordinary wrenches.
- Price: Compared to ordinary wrenches, the complex structure of a T-handle preset torque wrench makes the price a little higher, and there may be some maintenance costs.
How to Use a T-Handle Preset Torque Wrench?
After reading the above content, you may understand something about the T-handle preset torque wrench, but it's not enough for you to work with it. Next, we will explain how to use it step by step. Keep reading to master this tool and improve your working efficiency.
Step 1: Choose a compatible N/m T-handle preset torque wrench according to the material and nature of the workpiece.
Step 2: In the working process, apply force evenly in a clockwise direction and keep the wrench vertical from affecting the accuracy of the torque.
Step 3: When you hear a clicking sound or feel a vibration, it means the torque has reached the set level. At this time, the screw has been completely tightened. If you keep applying force, it may result in over-tightening of the fasteners or even damage the screws or wrench.
After using it, you need to put it in a safe place to prevent damage to the internal structure by accidental dropping.
