Torque Heads: The Essential Tool for Modern Screw Pile Installation

In today’s construction, utility, and ground engineering industries, there’s one tool that consistently stands out for efficiency, precision, and reliability: the torque head. Whether handheld or excavator-mounted, torque heads are transforming the way contractors install screw piles and anchors, delivering faster results with reduced environmental impact.

At Autoguide Equipment, we’ve been designing and manufacturing torque heads in the UK for decades. Our products are trusted across industries ranging from fencing and utilities to large-scale construction and renewable energy projects.

This blog will explore everything you need to know about torque heads—what they are, why they’re used, the industries they serve, and how to choose the right torque head for your project.

What Is a Torque Head?

A torque head is a hydraulic drive attachment designed to install helical (screw) piles by applying controlled torque to rotate the pile into the ground.

The torque applied during installation is directly related to the pile’s load-bearing capacity, making it a reliable method for ensuring foundations meet structural requirements. Unlike traditional concrete foundations, screw piles can be installed quickly, with minimal disruption, and often in areas where access is limited.

There are two main types of torque heads:

  • Handheld Torque Heads – Lightweight, portable units for restricted access areas such as gardens or under low headroom.

  • Excavator-Mounted Torque Heads – Heavy-duty attachments that deliver higher torque outputs for larger screw piles used in construction, utility, and infrastructure projects.


Why Torque Heads Are Essential

1. Speed and Productivity

With a torque head, screw piles can be installed in minutes, compared to the days required for traditional concrete foundations to cure. This keeps projects on schedule and reduces labour costs.

2. Accuracy and Reliability

The relationship between torque and pile capacity provides engineers with a built-in quality check. If the required torque is achieved during installation, the pile will support the designed load.

3. Reduced Environmental Impact

Screw piles leave virtually no waste and can be easily removed or reused. This makes torque head installations especially valuable for temporary structures, environmentally sensitive sites, and areas with tree root protection zones.

4. All-Weather Capability

Unlike concrete, screw piles can be installed in wet or cold conditions without delays, making torque heads an all-season solution.


Industries That Rely on Torque Heads

Construction and Ground Engineering

Torque heads are used to install foundations for modular buildings, extensions, log cabins, garden offices, and large-scale structures. They are particularly useful where access is limited, or ground conditions require deep, secure anchoring.

Utilities and Telecommunications

From electricity poles to telecom masts, torque heads make quick work of secure foundations. Utility contractors value torque heads for their speed, safety, and ability to handle poles in challenging locations.

Fencing and Agriculture

Farmers and fencing contractors use torque heads to install strong, long-lasting fence posts without concrete. This method reduces labour and avoids damage to surrounding ground.

Renewable Energy

In solar and wind energy projects, torque heads are used to install pile foundations quickly and sustainably. Their ability to support both permanent and temporary structures makes them ideal for off-grid and eco-conscious developments.


Autoguide Torque Head Range

At Autoguide Equipment, we offer a wide selection of torque heads designed for different applications and industries.

  • Handheld Torque HeadsOur 400H and 700H models are ideal for restricted access or sensitive sites. These compact torque heads are perfect for residential foundations, fencing, and landscaping projects.

  • Excavator-Mounted Torque HeadsRanging from 2.5kNm to 250kNm, our excavator-mounted torque heads are built for heavy-duty applications, including large construction sites, utilities, and infrastructure projects. They are designed to fit a wide range of excavators, from mini diggers to large carriers.

  • Custom SolutionsFor specialist industries such as offshore, subsea, and renewables, we can design torque head solutions tailored to unique project requirements.


Benefits of Choosing Autoguide Torque Heads

When contractors choose Autoguide, they benefit from:

✅ British Engineering – All torque heads are designed and manufactured in our Wiltshire factory.

✅ Durability – Built to withstand tough ground conditions and heavy use.

✅ Operator-Friendly Design – Safety and control are built into every model.

✅ Proven Track Record – Trusted by contractors across the UK and internationally.


How to Choose the Right Torque Head

Selecting the correct torque head for your project depends on several key factors:

  • Pile Size – Larger diameter piles require higher torque outputs.

  • Ground Conditions – Clay, chalk, and gravel will require different torque levels.

  • Site Access – Restricted sites may call for handheld torque heads.

  • Carrier Machine – Excavator-mounted torque heads must match your machine’s size and hydraulic capacity.

If you’re not sure which model is right for your needs, our team can provide guidance based on your project requirements.


Case Study: Screw Pile Foundations for Modular Buildings

A recent project involved installing screw pile foundations for a modular classroom on a school site with limited access. Traditional concrete foundations would have disrupted the school grounds and taken weeks to complete.

Using an Autoguide handheld torque head, the contractor installed 76mm screw piles in just two days, with minimal noise, waste, and disruption. The classroom was delivered and installed the following week, saving the school both time and money.


Frequently Asked Questions

Q: Can torque heads be used in rocky ground? A: Yes, but pile choice and torque head capacity are important. Our higher torque models are designed to cope with challenging ground conditions.

Q: Are torque heads only for permanent foundations? A: No. Screw piles can be easily removed, making torque heads ideal for temporary structures such as event stages, site offices, or temporary access ramps.

Q: Do torque heads require specialist training? A: While torque heads are straightforward to operate, training is recommended to ensure safety, accuracy, and compliance with project specifications.


The Future of Foundations

As the construction and utilities industries focus on sustainability and efficiency, torque heads will continue to play a key role in delivering reliable, eco-friendly foundations. With their speed, versatility, and reduced environmental impact, torque heads are the modern solution to an age-old challenge.


Conclusion

Torque heads are revolutionising foundation installation. From residential extensions to large infrastructure projects, they provide the speed, accuracy, and sustainability that concrete foundations cannot match.

At Autoguide Equipment, we’re proud to design and manufacture torque heads that support the future of construction, utilities, and renewable energy.
