Key Considerations When Selecting a Torque Wrench

To ensure optimum performance, safety, and longevity of your equipment, consider the following factors when selecting a hydraulic torque wrench for the job.

1. Accessibility – One of the first aspects to consider is how much physical space is available around the bolted joint. In confined or difficult-to-access areas, low-profile hydraulic torque wrenches like the Hi-Force TWH-N Series are ideal. These tools are specifically designed to fit into tight or recessed spaces, thanks to their narrow cassette heads and compact structure.

For more open spaces and general bolting applications, square drive models like the TWS-N Series are an ideal option.

2. Torque Output Requirements – Another crucial factor is the required torque range for your application. It’s important to identify both the minimum and maximum torque values needed for your operations. This ensures the tool you choose is capable of delivering the required force without being over- or under-utilised, which could affect performance and tool lifespan.

Hi-Force hydraulic torque wrenches offer standard torque capacities of up to 48,181 Nm (34,985 lbf.ft), making them suitable for a wide range of industrial needs.

3. Working Environment – The conditions in which the tool will be used also play a vital role in tool selection. Factors like extreme temperatures, humidity, exposure to chemicals, or the presence of flammable gases must all be considered.

In hazardous environments where the risk of ignition is present, use air-driven torque pumps to reduce the risk of explosion.

In standard industrial environments, electric torque pumps are often preferred for their precise pressure control and consistent performance.

Hi-Force offers a variety of both air and electric torque pumps, allowing users to match the right pump to their specific safety and application requirements.

4. Cassette and Socket Compatibility – To ensure reliable and repeatable torque application, the output head of the tool must be properly matched to the bolt size and type.

• Hex Cassette Selection: For low-profile torque wrenches, ensure the cassette matches the Across Flats (AF) size of the bolts.

• Impact Sockets: With square drive wrenches, select the appropriate impact socket size based on bolt dimensions.

Hi-Force provides a wide selection of heavy-duty impact sockets and interchangeable metric and imperial ratchet heads and to suit bolting application requirements.

5. Accessories – Depending on the application, you may need to adapt or enhance the tool for better control and accessibility by using suitable accessories. These include extended reaction arms, hexagon reducer bushes, square drive conversions kits, removable handle kits, backup wrenches, etc.

These accessories not only extend the functional range of the tool but also contribute to improved operator ergonomics and safer working practices.
