Understanding Impact Hex Drivers

An impact hex driver, also known as an impact driver, is a type of power tool that's used for driving screws and bolts into various materials. It delivers high rotational torque, which allows it to drive screws more efficiently than traditional screwdrivers or drills.

The impact hex driver operates by rotating the bit while simultaneously delivering a hammering action to enhance the force applied. This combination of rotation and force makes the impact driver particularly useful for driving large screws or removing stubborn, over-torqued screws.

Understanding how an impact hex driver works will give you a better grasp of how to use it effectively. Knowing what sets it apart from other tools in your toolbox can also help you decide when it's best to use the impact driver and when to opt for a different tool.

The Basics: Getting Started with Your Impact Hex Driver

Choosing the Right Bit

The first step in using your impact hex driver is choosing the right bit. Hex drivers use hex bits, which come in different sizes typically ranging from 1.5mm to 10mm. The size of the bit you should use depends on the size of the screw or bolt you're working with.

Using a bit that's too small could result in the bit slipping or the screw head getting stripped. On the other hand, a bit that's too large won't fit into the screw head at all. Therefore, it's crucial to match the bit size to the screw size accurately.

Securing the Bit

Once you've chosen the right bit, the next step is to secure it into the chuck of the driver. The chuck is the part of the driver that holds the bit. It should be tightened enough that the bit fits snugly and doesn't wobble during operation.

To secure the bit, you typically need to pull forward the chuck, insert the bit, and then release the chuck. Ensure the bit is seated correctly and securely before proceeding.

Practising Control

Operating an impact hex driver requires a certain level of control. As a beginner, you can start by practising on scrap material. Begin with low torque settings and gradually increase as you gain confidence. Remember, the goal is to drive screws accurately and efficiently, not to drive them as fast or as forcefully as possible.

Advancing Your Skills: Intermediate Techniques for Using Impact Hex Drivers

Mastering Torque Control

One of the key skills you need to develop when using an impact hex driver is torque control. The torque refers to the force that causes rotation. In the case of impact drivers, this is the force that drives the screw into the material.

Impact drivers typically come with adjustable torque settings. Learning how to adjust these settings and understanding how different levels of torque affect the screw and the material is crucial. Too much torque can strip the screw head or damage the material, while too little torque may not drive the screw in fully.

Perfecting Angle of Drive

The angle at which you drive the screw can significantly affect the end result. Ideally, you want to aim for a 90-degree angle between the driver and the work surface. This angle ensures the most effective transfer of force from the driver to the screw.

However, there may be situations where it's not possible to achieve a perfect 90-degree angle. In such cases, it's important to maintain as straight an angle as possible to prevent the screw from going in crooked or the bit from slipping out of the screw head.

Powering Up: How to Use a Powered Hex Driver

Understanding the Tool

A powered hex driver operates similarly to a manual one but uses electricity or battery power to deliver the rotational force. This means it can deliver greater torque and drive screws more quickly and efficiently.

Before using a powered hex driver, familiarize yourself with its components and functions. Understand where the power switch is located, how to adjust the torque settings, and how to change the direction of rotation.

Adjusting Speed and Torque

Most powered hex drivers come with adjustable speed and torque settings. These settings allow you to customize the operation of the driver to suit the task at hand.

As a rule of thumb, start with low settings and adjust upwards as necessary. Remember, the goal is not to drive the screw in as fast as possible but to do so accurately and efficiently.

Using the Reverse Function

Powered hex drivers typically come with a reverse function. This function allows you to remove screws as well as drive them in.

To use the reverse function, you usually need to flip a switch or press a button on the driver. Make sure you understand how to engage this function safely and effectively before you need to use it.

Expert Tips: Utilizing Your Impact Hex Driver Like a Pro

Investing in Quality Bits

High-quality bits are less likely to strip screws or break during use. They typically offer a better fit with the screw head, which reduces the risk of slipping and allows for more efficient transfer of force.

While quality bits may cost more upfront, they can save you time and frustration in the long run. Consider investing in a set of bits in various sizes to ensure you always have the right bit for the job.

Maintaining Your Tool

Regular cleaning and maintenance can greatly extend the life of your impact hex driver. This includes checking for wear and tear, lubricating moving parts, and storing the driver in a dry, dust-free environment.

In addition, always ensure the driver is disconnected from the power source before performing any maintenance or bit changes. Safety should always be your top priority when using power tools.

Safety First

Speaking of safety, it's crucial to always use protective eyewear when operating your impact hex driver. The driver can generate a lot of force, which can send small particles flying. Protecting your eyes can prevent serious injuries.

In addition, ensure your work area is clear of hazards. Keep your hands and other body parts away from the rotating bit, and never attempt to hold the workpiece with your hand while driving screws.


Mastering the use of an impact hex driver requires time, practice, and patience. From choosing the right bit to mastering torque control and moving onto powered drivers, each step brings you closer to becoming a pro. But remember, even the most seasoned professionals are always learning and refining their skills. 

So, keep practicing, stay curious, and let your work speak for itself. With time and experience, you'll be wielding your impact hex driver like a true professional, bringing efficiency and finesse to all your DIY projects.
