Heavy-duty torque wrenches from the Bosch Rexroth Africa

Torque wrenches are used to tighten fasteners such as bolts and nuts to the exact specifications of the item. Over-tightened fasteners could result in damage and under-tightened fasteners could result in insecure connections of components that can fall apart.

Ensure correct tension for increased safety, efficiency, and uptime!

  • Low weight, high strength design
  • Superior, precise torsional strength
  • Floating piston design
  • Rigid steel body construction
  • Quick interchangeable heads

About torque wrenches

Bosch Rexroth Africa sources its range of torque wrenches from SPX Flow Bolting Systems, leaders in their field. These heavy-duty torque wrenches allow users to monitor the torque applied to the selected fastener in order to match the particular application’s specifications. This creates precise tensioning and loading of all parts.

Torque wrenches usually feature a torque meter or dial for users to adjust their desired torque value, which is often measured in units like pound-feet (ft-lb) or newton meters (Nm). Once the predetermined torque has been reached, an internal mechanism prevents the wrench from applying force to prevent users from overtightening their nuts and/or bolts.

Torque wrenches are typically used in the aerospace, automotive, construction, industrial, manufacturing, and mechanical industries, among other high-stake industries, to achieve secure nut and bolt connections. Types of torque wrenches include square drive, low clearance and high cycle torque wrenches .

Use Bosch Rexroth Africa’s range of high-quality wrenches from reputable brands for optimal performance and safety!

Why use torque wrenches from Bosch Rexroth Africa?

Our range of torque wrenches is sourced directly from the leaders in bolting systems, SPX Flow Bolting Systems, which manufactures the best torque wrenches. Covered a lifetime warranty, all wrenches in our range allow users to monitor the torque applied to the selected fastener, ensuring your application’s requirements are met!

Electric torque tools are featured in our torque wrench range.

Reliable hydraulic torque tools for safe and effective operations.

Our torque wrench range is supplemented with additional equipment like the torque wrench pump range, which includes electric torque wrench pumps and torque wrench pumps for air.

Bosch Rexroth Africaalso offers bolt tensioners as part of its bolting solutions offering, and its torque wrench range is, for the most part, hydraulic torque wrenches.

How to look after your torque wrench properly

  • Storage: If you need to store your torque wrench for long periods, wind it down to the minimum scale setting but not zero.

    A fully-loaded torque wrench stored for long periods may result in a set in the spring, weakening it over time. However, if the spring is completely off-loaded, other wrench components might move, even just by a fraction. When spring compression is reapplied, the orientation of these components can change and affect accuracy.

  • One click is enough for accurate results. When a torque wrench clicks multiple times, it applies additional torque to the bolts.
  • Using a torque wrench for anticlockwise threads. To ensure tool suitability and to prevent loss of torque control, check the specifications of the wrench before using it on an anticlockwise thread.
  • Converting torque units. Converting torque units is a very precise process, and a tricky one too. Torque unit converters and torque conversion calculators can be downloaded to assist with the process.
  • Use the marked loading point. Most torque wrenches feature a marked loading point on the handle. To achieve the most accurate results, torque wrenches should be operated with the user’s hand centred over the marked load point. The load point must also be used when calibrating the torque wrench.
  • Undoing with a torque wrench. Most torque wrenches can be used for undoing as long as the maximum torque is not exceeded. Exceeding the maximum torque limit during a bolt loosening can affect wrench accuracy.
  • Extending the torque wrench handle. Do not put a pipe or any other extension onto a torque wrench handle. In addition to it being a potential safety hazard, it can damage the tool and reduce its accuracy.
  • Apply the adjustment lock. Wrench settings can be accidentally adjusted during use. To avoid this, always apply the adjustment lock (if fitted) to avoid unintended changes.
  • Applying ‘crows foot’ type fitting. ‘Crows foot’ type fittings can be applied to a torque wrench square drive, but the torque will be altered. If you apply this setting, ensure that a suitable offset is applied to the set torque.
  • Adjusting a torque wrench. When adjusting your adjustable torque wrench, always ensure that the required torque levels provided by the manufacturer are met. Always adjust the wrench up the scale to the required torque figure to ensure an accurate setting.

Frequently asked questions:

Why is it called a torque wrench?
A torque wrench is used where the tightness of screws and bolts is crucial. It applies specific torque to fasteners like nuts, bolts, or lag screws and is in the form of a socket wrench with special internal mechanisms
Are digital torque wrenches worth it?
If you’re looking for high accuracy, digital torque wrenches are the way to go. However, they generally have a delicate construction, which requires extra care while handling. A digital torque wrench requires batteries to operate, something to consider when weighing the pros and cons of digital torque wrenches.
Is a ratchet the same as a torque wrench?
A torque wrench and a ratchet are not the same. A ratchet is a plain wrench designed for loosening and tightening bolts. Torque wrenches, however, are used where precise torque settings are required for a specific bolt, like in tasks in the automotive sector.
Can one undo bolts using a torque wrench?
Most torque wrenches can be used for undoing bolts, as long as the maximum torque is not exceeded. If the maximum torque limit is exceeded when loosening a bolt, it can affect the accuracy of the torque wrench.
What does a torque multiplier do?
A torque multiplier (or torque multiplier wrench) is a tool used to increase the amount of applied torque, which enables more rapid assembly and disassembly of heavy machinery and structure, among others.
How do you convert torque units?
Torque is measured by multiplying the amount of force applied and the distance from the point of application. That is the reason that the torque amount is written in units of force and distance.
How do you calibrate torque wrenches?
The International Organization of Standardization (ISO) says a torque wrench should be re-calibrated every 5000 uses or every 12 months. It is advisable to have the calibration done in a testing laboratory. However, you can assemble a torque wrench calibrator and do the testing yourself, but you will need to determine the calibration ratio and multiply that amount by the required bolt torque.
What is meant by torque angle?
Torque angle replaces a maximum torque value for a fastener with a specific amount of fastener rotation. After setting a low baseline torque, just to make sure the fastener is set, the fastener is rotated a precise amount to set the final position and clamp load.
What is torque range?
Torque wrench sizes and capacity range from small, to medium, and large. The torque range for small-sized models varies from 30-200 inches.
