Torque Screwdrivers

A torque driver is a screwdriver with components that ensure tightening to a specified torque. They enable any consumer to deliver the correct torque with confidence regardless of task and operator skill level, making them a must-have in any tool kit.

What is a Torque Driver?

What distinguishes a torque screwdriver from a standard screwdriver? Regular screwdrivers, like those you might get in a traditional screwdriver set, cannot detect or control how much force is applied to a screw; only torque screwdrivers can. Why is that crucial? Because a screw may come out of the hole if you don't use enough effort while driving it in. Conversely, applying too much may harm the substrate or the screw, increasing the likelihood that the whole assembly will collapse under stress either right now or in the future.

At RS Malaysia, you can buy a torque screwdriver set or an adjustable torque screwdriver, which allows you to set specific inch-pound settings, ensuring precise torque application.

How to Use a Torque Screwdriver

Using a torque screwdriver is straightforward, but there are a few key steps to ensure proper and safe operation:

Adjust the Torque Setting

• Ensure the torque value is set to the specifications required for the task.
• Adjust the torque setting on the screwdriver to the appropriate value, whether it's a preset, adjustable, or digital model.
• Double-check the torque setting to avoid over-tightening or under-tightening the fasteners.

Choose and Fit the Appropriate Screwdriver Tip

• Select the appropriate screwdriver bit or tip that matches the screw head size and type.
• Firmly insert the tip into the screw head, making sure it is properly seated.

Apply Torque Slowly and Steadily

• Grip the torque screwdriver handle and apply torque slowly and steadily.
• For hand tools, use your body weight and leverage to apply the necessary force.
• For powered tools, let the motor do the work and avoid excessive force.

Monitor the Torque Indicator

• Watch for the torque screwdriver's indication that the desired torque has been reached, such as a "click" or "slip" on a hand tool or a digital readout.
• Stop applying force once the torque indication is triggered to prevent over-tightening.

Repeat as Needed

• Move on to the next screw, repeating the process to ensure consistent torque is applied across all fasteners.

How Do They Work?

Torque screwdrivers are designed to apply a specific amount of force, measured in inch pounds, to a screw. By setting the desired torque, the screwdriver prevents over-tightening, ensuring components are securely fastened without damage.

What materials are they made from

Torque drivers are typically made from steel with ergonomic multi-component handles. As a result, you can expect the best adjustable and preset torque screwdrivers to be sturdy and durable even with extended use and for heavy-duty applications.

Types of Torque Drivers

By their method of propulsion, the many varieties of torque screwdrivers may be divided into three major groups: pneumatic, electric, and manual. The ideal one for your use will rely on your intended production rate, needed torque output and precision, documentation requirements and the size of the screw you'll be dealing with. Here are some of the types of torque screwdrivers we carry at RS Malaysia:

• T-bar Torque Drivers - T-bar torque drivers are a type of hand torque screwdriver that feature a T-shaped handle. This design provides more leverage and allows the user to apply higher torque values compared to standard straight-handle screwdrivers. The T-bar shape gives the user more control and stability when tightening screws that require higher torque.
• Electric Torque Drivers - Electric torque drivers are powered by an electric motor, providing faster operation and more precise torque control compared to manual hand tools. They are well-suited for high-volume or delicate assemblies where consistent torque is critical. Electric torque drivers can be integrated with automated systems and some models are designed to prevent electrostatic discharge, making them safe for electronics work.
• Preset Torque Screwdrivers - Preset torque screwdrivers are hand tools that are factory-calibrated to a specific torque value. They use an internal mechanism that "clicks" or "slips" once the preset torque is reached, preventing over-tightening. Preset screwdrivers offer reliable, repeatable torque application but require a separate screwdriver for different torque settings.
• VDE Torque Drivers - VDE (Verband Deutscher Elektrotechniker) torque drivers are a specialised type designed for working on live electrical equipment. They feature an insulated handle and other safety features to protect the user from electric shock hazards. VDE torque drivers allow technicians to properly tighten live electrical connections safely.
• Digital Torque Screwdrivers - Digital torque screwdrivers use electronic sensors and displays to provide a precise, digital readout of the applied torque. This allows the user to accurately monitor and control the torque being applied, ensuring consistent and reliable results. Digital models often include features like data logging and wireless connectivity.
• Adjustable Torque Limiting Screwdrivers - Adjustable torque limiting screwdrivers allow the user to set the desired torque value, then automatically disengage or "slip" once that torque is reached. This prevents over-tightening and damage to delicate components.

The ideal torque screwdriver type will depend on the specific requirements of the application, such as required torque range, production speed, screw size, and the work environment. Many businesses utilise a combination of different torque screwdriver types to meet their diverse needs.

Uses of Torque Drivers

Torque screwdrivers are used in mechanical production, manufacturing, and maintenance. Their use provides quality assurance as small variations in the torque used during high-volume production might result in large percentages of product loss. Additionally, the loss of one screw may have disastrous effects on extremely sensitive goods. As a result, businesses from a variety of sectors depend on torque screwdrivers to produce goods in a way that is secure, efficient, and lucrative. At RS Malaysia, we welcome you to buy the best adjustable and preset torque screwdrivers/drivers from brands like Wiha, Wera, STAHLWILLE and more.

The Application of Torque Screwdrivers in Different Industries

Electronics

In the electronics industry, torque screwdrivers are indispensable for assembling delicate electronic components with precision. These tools help prevent damage from over-tightening screws on sensitive circuit boards and connectors, which are widely used in this field. For instance, when securing the tiny screws on a smartphone's motherboard, a digital torque screwdriver can be used to ensure the right tightness without compromising the integrity of the fragile components.

Medical Manufacturing

Torque screwdrivers in medical manufacturing ensure that devices meet stringent safety standards. These tools are vital for assembling the many small and intricate devices used in the medical field, such as pacemakers, surgical instruments, and orthopaedic implants that require consistent and precise screw tightness to maintain structural integrity and function. This ensures that all fasteners are tightened to a specific, pre-set torque, reducing the risk of malfunction during critical medical procedures.

Automobile Manufacturing

In automobile manufacturing, torque screwdrivers are crucial for assembling components that must adhere to precise specifications for safety and performance. A T bar torque driver, for example, is often used for engine and brake assembly where precise torque application is necessary to ensure components are securely installed without stripping or damaging threads. This consistency ensures that all parts are securely fastened and will perform reliably under various driving conditions, contributing to vehicle safety and customer satisfaction.
