A torque wrench is a precision tool engineered to apply a precise amount of torque to fasteners like nuts and bolts. This ensures they're neither too loose nor too tight, which is essential for the integrity and safety of any assembly. If you're in the market to buy a torque wrench in Malaysia, it's important to understand their various types and applications.

## **What is a Torque Wrench?**

A torque wrench is a specialised wrench that allows the user to set a desired torque level. It typically includes a scale or digital readout for setting and measuring torque. Some models will also provide an audible click or a visual indicator when the preset torque is reached. This prevents over-tightening or under-tightening fasteners, which can lead to component damage or failure.

## **Types of Torque Wrench**

**Breaking Torque Wrench (or break-over torque wrench):** features a pivot point or hinge which ˈbreaks overˈ when the pre-set torque is reached. This allows the handle to move or rotate indicating that the required torque has been applied.

**Slipping Torque Wrench:** Slipping Torque Wrenches disengage or slip once the pre-set torque is reached, preventing further torque application.

**Click Torque Wrench:** Click Torque Wrenches use a mechanical mechanism that produces an audible or tactile click when the pre-set torque is reached.

**Dial Torque Wrench:** Dial Torque Wrenches utilise a dial or gauge with a calibrated scale and rotating needle to display the applied torque and indicate the torque value applied. It is ideal for applications requiring high accuracy.

**Digital Torque Wrench:** [Digital Torque Wrenches](https://my.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4290544019) often feature a digital display to provide accurate torque readings. Torque settings can be adjusted and additional features like audible or visual alerts may display when the required torque has been applied.

**Smart Torque Wrench:** Smart Torque Wrenches incorporate wireless connectivity such as Bluetooth or WiFi to connect to mobile devices or a computer network via an app or software.

Torque wrenches are available in popular drive sizes such as in, in & [3/8 in](https://my.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4294440119) from leading brands such as [Wera](https://uk.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4294964448), [Facom](https://my.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4294966612) and [Norbar](https://my.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4291882924). [Torque Wrench Sets](https://my.rs-online.com/web/c/hand-tools/spanners-sockets-wrenches/torque-wrenches/?applied-dimensions=4290543767,4290543963) are also available and, for additional precision, Calibrated Torque Wrenches can be purchased.

## **Industrial Application of Torque Wrenches**

Torque wrenches are essential tools across various industries to ensure precise and accurate fastener tightening, preventing over tightening or under tightening that can lead to equipment failure or safety hazards.

### **Automotive**

In the automotive industry, torque wrenches are used extensively for assembling and maintaining vehicles. They are crucial in tightening lug nuts on wheels, engine components, suspension systems, and other critical parts. Proper torque ensures the safety and reliability of vehicles on the road, preventing accidents caused by loose or overtightened fasteners. Mechanics and technicians often rely on a torque wrench set to cover a wide range of applications.

### **Aerospace**

The aerospace industry demands high precision and accuracy in every aspect of manufacturing and maintenance. Torque wrenches, especially dial torque wrenches or torque indicating wrenches, are used to tighten fasteners on aircraft engines, fuselage structures, landing gear, and other critical components. Precise torque control is vital to ensure the safety and airworthiness of aircraft, preventing catastrophic failures during flight.

### **Construction**

In construction, torque wrenches are used for assembling and securing steel structures, fastening bolts in heavy machinery, and tightening connections in piping systems. The ability to apply the correct torque is essential for maintaining the structural integrity of buildings, bridges, and other infrastructure projects. Construction professionals often prefer a dial type torque wrench or dial gauge torque wrench for its clear visual indication of applied torque.

### **Oil and Gas**

The oil and gas industry relies on torque wrenches to ensure the safe and reliable operation of drilling rigs, pipelines, and other equipment. These tools are used to tighten fasteners on valves, flanges, and other critical components, preventing leaks and ensuring the integrity of the infrastructure. In hazardous environments, the accuracy of a torque wrench is paramount to preventing accidents and ensuring worker safety.

### **Marine**

Torque wrenches are indispensable in the marine industry for shipbuilding, maintenance, and repair of vessels. They are used to tighten fasteners on engines, propellers, hulls, and other critical components. Proper torque ensures the seaworthiness of ships and prevents accidents caused by loose or overtightened fasteners. Marine engineers and technicians often use torque wrenches in challenging conditions, requiring durable and reliable tools.

## **Frequently Asked Questions About Torque Wrenches**

### **How do you dial a torque wrench?**

To dial a torque wrench, loosen the handle lock, rotate it until the desired torque value aligns with the indicator, and then retighten the lock. Ensure to use the correct scale (Nm, ft-lb, etc.) for your application.

### **Are dial wrenches more accurate?**

Dial torque wrenches are often considered more accurate than click-type torque wrenches due to their clear visual display and precise adjustment mechanism. However, both types can be highly accurate when properly calibrated and used.

### **How to choose a torque wrench?**

When choosing a torque wrench, consider the required torque range, drive size, accuracy, and application. A torque wrench set might be ideal if you need to cover all your bases. If you need assistance, you can consult with torque wrench suppliers like RS Malaysia to find and buy the right tool for your needs at a great price.

### **Do torque wrenches lose accuracy?**

Yes, torque wrenches can lose accuracy over time due to wear and tear, improper use, or lack of calibration. It's essential to regularly calibrate your torque wrench to ensure accurate readings and prevent over tightening or under tightening of fasteners.

### **How long do torque wrenches last?**

The lifespan of a torque wrench depends on its quality, frequency of use, and maintenance. With proper care and regular calibration, a high-quality torque wrench can last for many years. However, it's important to replace worn-out or damaged components to ensure continued accuracy and reliability.
