When Using High-Velocity Tools, Do Not Drive Fasteners Closer Than Required

High-velocity tools are an essential part of any construction and maintenance work. These tools use compressed air to drive fasteners into various materials, such as wood, metal, and concrete. They are fast, efficient, and can significantly improve work productivity. However, it is crucial to use them properly and follow safety guidelines to avoid accidents and guarantee the desired results. One common mistake that many people make when using high-velocity tools is driving fasteners closer than required. In this article, we will explore why this is a problem and how to avoid it.

The Dangers of Driving Fasteners Too Close

Driving fasteners too close to the surface can cause several problems that can affect both the tools and the materials being fastened. Here are some of the dangers of driving fasteners too close:

1. Splitting and Cracking

Driving fasteners too close to the surface can cause the material to split or crack. This occurs mainly in wood and other brittle materials. The pressure from the fastener can cause the fibers to break, resulting in a weaker and less attractive finish.

2. Damage to the Tool

Driving fasteners too close can also damage the high-velocity tool. The tools are designed to work with a specific depth, and operating outside that range can cause significant wear and tear. This can lead to unnecessary repairs or even replacement of the tool.

3. Reduced Holding Power

When a fastener is driven too close, there is not enough grip to hold the material securely in place. This can cause the fastener to loosen, resulting in a weaker structure that is prone to collapse or damage.

4. Uneven Surfaces

Driving fasteners too close can also result in uneven surfaces. This can be especially problematic when the material being fastened is a visible part of the structure. Uneven surfaces can detract from the appearance of the structure and reduce its value.

Avoiding Driving Fasteners Too Close

Fortunately, it is easy to avoid driving fasteners too close. Here are some steps you can take to ensure that you fasten materials correctly:

1. Know the Optimal Depth

Every high-velocity tool comes with a manual that specifies the optimal depth for driving fasteners. Always read the manual to understand the proper depth range for your tool.

2. Use Depth Stops

Depth stops can be attached to high-velocity tools to ensure that fasteners are driven to the optimal depth. These stops can be adjusted to match the thickness of the material being fastened.

3. Use the Right Fasteners

Using the right fastener for the job is also important. Be sure to choose fasteners that are appropriate for the material being fastened, and that fit the depth requirements for your tool.

4. Test the Depth

Before driving fasteners, always test the depth on a piece of scrap material. This will allow you to adjust the depth stop and ensure that the fastener is driven to the optimal depth.

5. Inspect the Results

After fastening the material, inspect the results carefully to ensure that the fasteners are not too close to the surface. If necessary, make adjustments to the depth stop and re-fasten the material.


High-velocity tools are a vital part of construction and maintenance work. They can significantly improve productivity and efficiency when used correctly. However, it is crucial to follow safety guidelines and use the tools properly to avoid accidents and damage. Driving fasteners too close can cause several problems, including splitting and cracking of the material, damage to the tool, reduced holding power, and uneven surfaces. To avoid these issues, always follow the optimal depth range for your tool, use depth stops, choose the right fasteners, test the depth, and inspect the results. By doing so, you can ensure that your fasteners are secure and that your work is of the highest quality.
