What Is Dial Torque Wrench
Dial torque wrenches are used to test and monitor the amount of torque necessary for fastening. This kind of wrench is ideal for torque auditing and measurement applications because it has memory settings on the dial display that give the operator a quick visual torque verification test.
Construction Industry: Used for fastening in steel structure buildings to enhance stability and durability. For example, tightening bolts in building structures to ensure safety and stability.
Flat Type Portable Torque Multipliers
Flat Type Portable Torque Multipliers are suitable for loading and unloading nuts and bolts in small spaces but with large torque values. The operator only needs to apply a small torque to obtain a 4-29 times torque amplification output through the planetary gear reduction mechanism, so as to easily complete the tightening or disassembly of bolts and nuts.
Preset Type Manual Torque Wrench
(1)Preset torque value: The user can pre-set a specific torque value according to the requirements of the fastener.
(2)Precision control: The torque wrench can accurately control the applied torque value through its internal mechanical structure or electronic device, thereby ensuring the installation quality of the fastener.
(3)Feedback signal: When the preset torque value is reached, the wrench will send a signal to prompt the user.
Preset Torque Wrench Set is a set of torque wrenches with various specifications and torque values. By presetting specific torque values, it provides precise torque control during the tightening process of fasteners, ensuring that fasteners are properly tightened and preventing damage or safety hazards caused by over tightening or insufficient torque.
Preset torque value: Users can preset a specific torque value on the wrench as needed. When the wrench reaches this value, it will make a click sound to prompt the user that the preset torque has been reached, thereby ensuring that the fastener is properly tightened.
Preset Click-Type Torque Wrench
Powerful and Reliable: Designed to provide the force required to tighten any bolt, it is more economical than other types of torque wrenches and can handle higher torque values.
Durability: With all-steel structure and corrosion-resistant surface treatment, it is suitable for various industrial environments such as aerospace, automotive, machinery, chemical, nuclear energy, energy, etc.
(1)High Precision: The Preset Slipping Torque Wrench is able to provide ±6% torque control, ensuring that the bolt or nut is accurately tightened to the required torque value.
(2)Prevent Overtightening: Since it automatically releases when the preset torque value is reached, it can effectively prevent damage to the bolt or nut caused by overtightening.
1. Please do not disassemble or knock at will to avoid affecting the accuracy of the product.
2. The outer ring of the dial is a plastic part, avoid contact with high temperature to avoid damage.
3. Please do not use it beyond the torque range.
Preset Non Adjustable Torque Wrench
Do not use preset torque wrenches to remove bolts or nuts to avoid damage to the tool or affect the accuracy.
• It is strictly forbidden to add a sleeve extension arm to the end of the torque wrench to prevent damage to the torque wrench.
When you put an extension on a dial torque wrench (e.g. a crow foot or a dog bone) the torque applied to the fastener increases as the lever arm extends. The calculator will work out what value you should set into the wrench to achieve the required fastener torque.
The following formula has been used:
M1 = M2 x L1 / L2
Where:
- M1 is the torque setting of the wrench
- M2 is the actual torque applied to the nut
- L1 is the normal length of the wrench
- L2 is the extended length of the wrench
How to Use a Dial Torque Wrench
Designed to take the guesswork out of learning how to set a torque wrench correctly for a particular job, digital varieties do much of the work for you. dial torque wrenches can ensure that you always have the correct torque setting for the job at hand, leading to less issues down the road.
Dial torque wrenches are commonly used in manufacturing and production facilities where extreme precision is key, but they can be used in other capacities and at home as well:
Step 1: Set the torque value on your dial torque wrench. Most models feature a "SET" button and up or down arrows that allow you to change the torque value.
Step 2: Program the tolerance parameter to control the "Go" and "No-Go" signal responses. Set the upper and lower thresholds for safety and quality control purposes.
Step 3: Place your torque wrench and begin making adjustments. On most dial torque wrenches, a buzzer or light will indicate when you should stop applying torque.
Step 4: Check your reading. Most dial torque wrenches use a green light to let you know the correct torque has been achieved. A red light indicates the torque was not within the correct tolerance zone.
Dial torque wrench in regular use doesn't need to be wound back. If you expect to store a dial torque wrench for more than a few weeks, always wind it down to the lowest scale setting (never to zero).
Storing a fully loaded dial torque wrench can result in a set in the spring, weakening the spring over time. But if you completely offload the spring to the zero setting, other components within the wrench may move a little. And in the world of torque, a little is a lot. Reapplying spring compression will shift the orientation of these components, affecting accuracy.
8 Best Practices When Using Dial Torque Wrenches
Dial torque wrenches have been around for decades and are still the primary choice for providing an exact amount of force required for correct bolt tightening. It is due to their accuracy of high torque values, that they have gained incredible popularity over the years, but it is because of the high force they provide that it is imperative they're used in the correct manner.
By ensuring users follow the correct procedure for usage and set up, it will provide the best results and ensure operator safety.
Here are 8 best practices to help improve safety and efficiency when using a dial torque wrench:
Know the recommended range: Recommended ranges are to protect the operator and dial torque wrench itself from injury and damage. Exceeding these recommended ranges increases the risk of unreliable results and even injury. On average, a dial torque wrench range is 20 to 100% of full scale and for electronic wrenches, that range is 10 -100%.
Don't use extensions or adaptors: Using extensions or adaptors increases the risk of injury and causing damage the wrench by accidental inaccuracy. If there are no recommended extensions by the manufacturer, you must never use one.
One-click is enough: Users often click multiple times without being aware additional torque is being applied and this causes more force to be exerted than required, this risks damage to your wrench. Using the "one-click is enough" method allows you to achieve the desired torque accurately in a controlled manner.
Equipped storage: Always store your dial torque wrench in a protective case and follow manufacturers guidelines for storage to prevent damage to the spring, if stored for long periods of time.
An anticlockwise thread: Most dial torque wrenches will indicate the clockwise direction, so check the specification before using in an anti-clockwise direction to prevent losing torque control.
Calibrate correctly: If calibrated incorrectly or not at all, it can cause unknown torque values. Always know to inspect your tool prior to use and recalibrate your wrench at regular intervals, either on an annual basis or in-line with manufacturers guidelines.
Lock for safety: Always apply the adjustment lock before operating if the wrench is fitted with one. Many injuries happen when accidental and unintended changes to the wrench settings occur.
Protect yourself: Always wear the required Personal Protection Equipment (PPE) such as safety glasses to protect the eyes, and the correct work gloves to protect hands from injuries.
Use of Dial Torque Wrench
Flip the ratchet lever to the appropriate position - To the right if tightening clockwise, to the left if tightening counterclockwise.
Determine the recommended torque for the fastener or component in question.
Push in the locking ring at the base of the handle and turn counterclockwise. Torque setting is determined by adding two numbers: The number directly above the red line in the scale window and the number aligned with the marker on the locking ring. Release the locking ring once the desired setting has been achieved.
Install the socket or bit onto the dial torque wrench by pushing the ball detent release button on the back of the wrench and engaging the socket.
Engage the socket or bit onto the fastener or component. Be sure the socket or bit is fully engaged and oriented squarely.
With your hand centered on the handle of the wrench, slowly apply force to the handle.
Keep an eye on the head of the dial torque wrench - once the head of the wrench deflects, the set torque value has been achieved. This deflection is often accompanied by a click, but may not be.
The general principle of a dial torque wrench is that as torque is applied to a fastener, the dial torque wrench uses a calibrated mechanism to display the torque applied or otherwise indicate when a specified torque has been reached. The three most common types of dial torque wrenches are beam type, click type, and digital.
The handle rod is designed to bend as torque is applied to the fastener. The torque display scale remains unbent allowing the relative angle between each rod to indicate the torque. These are the least expensive and simple type of dial torque wrench, but rely on the user to constantly look at the torque scale. This may be challenging in some bicycle applications where wrench positioning is limited.
A digital torque wrench uses a strain gauge attached to a torsion rod to measure torque and convert it into the common torque units using a processor. The digital torque wrenches work on similar principles as a beam type torque wrench, but are more advanced, displaying the torque value digitally as the fastener is tightened. In addition, many digital torque wrenches sounds a digital alarm when a preset torque value is reached.
Does a Dial Torque Wrench Stop When It Reaches Its Torque
● Dial torque wrenches are designed to apply a specific amount of force to a bolt to prevent under-tightening or over-tightening, which can damage parts or leave them insecure.
● While some dial torque wrenches have indicators to show when the desired torque is reached, they do not stop applying force automatically. Instead, some models may emit a click or other signal to indicate the torque has been achieved.
● Proper use involves setting the wrench to the specified torque level before use, and it is essential to calibrate the wrench regularly to maintain accuracy.
There are different kinds of dial torque wrenches, from the simplest to the most sophisticated, all of which are designed to measure the torque value: The amount of force applied while fastening a nut or bolt. They're all tools designed to both fasten properly and to prevent over-tightening or under-tightening a bolt. Over-tightening can cause damage to the fastener, and under-tightening can result in making the item you are attaching or assembling structurally weak and potentially unsafe for use.
Some dial torque wrenches require constant reading of the torque indicator, so that you know when to stop twisting the bolt. Some have a dial to set the required torque, but the indicator doesn't stop applying force automatically when torque is reached. They may have a visual signal such as a digital reading or an audible beep or click. Some dial torque wrenches are difficult to use in tight places where reading a gauge or indicator may not be possible, as in automotive applications. A click dial torque wrench can be preset to a specific torque level. The wrench has a clutch mechanism that makes a clicking noise and slips when the maximum level is reached to prevent exceeding the preset torque level.
How to Maintain Your Dial Torque Wrench
Dial torque wrenches are precision tools and should be treated with the utmost care.
Maintaining your dial torque wrench requires regular checking for wear and tear as well as keeping a close eye on potential defective parts.
The more you use your dial torque wrench the faster is will begin to show signs of wear.
● Inspect the ratchet
The wrenches ratchet should be regularly cleaned and lubricated. You should also periodically check that the screws in the head are tight. The handle should not be loose and should not contain any lubricant or corrosion when being used.
● Store correctly
Always keep your dial torque wrench dry and store it in an appropriate case to protect it from chemicals, grime and dust. Before storing, make sure to wipe down your wrench with a clean cloth as residue liquid could damage or corrode the wrench over time if left unattended.
● Follow instructions
If you ever need to disassemble your dial torque wrench always make sure you follow the provided instructions carefully and if necessary, use a competent technician instead.
