Mastering Precision: The Brad Nailer Shooting Two Nails

In the world of carpentry and construction, the brad nailer is an indispensable tool, beloved for its ability to drive small, discreet nails with precision. Among the various applications, there’s an intriguing aspect that often arises in the realm of brad nailers – the phenomenon of a brad nailer shooting two nails at once. While this may sound like a nuisance, it can be a fascinating quirk, and in this comprehensive guide, we’ll explore this phenomenon in detail. We’ll delve into the causes, implications, and how to handle a brad nailer that seems to have developed this peculiar talent.

The Brad Nailer: A Marvel of Precision

Before we unravel the mystery of the brad nailer shooting two nails, let’s take a moment to appreciate this remarkable tool. Brad nailers are renowned for their ability to drive fine-gauge nails, typically 18-gauge, with exceptional accuracy. They excel in tasks like attaching trim, molding, or delicate woodwork, leaving minimal marks or damage.

The Mysterious Double Shot

Imagine the scenario – you’re working diligently, attaching delicate trim to a beautiful piece of cabinetry, and you squeeze the trigger on your brad nailer. But instead of a single, precise nail, you hear a faint double pop, and there they are – two brad nails side by side. What just happened?

The Causes

  1. Misaligned Nails: One of the most common causes of a double shot is misaligned nails in the magazine. If two nails are not perfectly aligned and you fire the gun, both nails may be driven simultaneously.

  2. Weak Driver Blade Spring: A worn or weak driver blade spring might not have the force to return the driver blade to its original position after driving a nail, causing it to strike the next nail as well.

  3. Air Pressure Issues: Inconsistent air pressure can lead to uneven firing. If the pressure is too high, it may drive two nails, especially in softer materials.


While a brad nailer shooting two nails might seem like a mishap, it’s not necessarily a catastrophe. In some cases, it can even be advantageous. Here’s how to deal with the situation:

  • Perfect Alignment: If two nails land precisely where you intended, it might save you from having to make a second pass, ultimately saving time.

  • Spacing Control: In certain situations, a double shot can be beneficial for controlling spacing between nails on delicate materials.

However, in most cases, the double shot is unintentional and can result in damage to the material or create an uneven finish. It’s crucial to understand how to address this issue effectively.

Dealing with a Brad Nailer Shooting Two Nails

If you find your brad nailer frequently shooting two nails, it’s time to take action. Here are some steps to resolve the issue:

  1. Check Nail Alignment: Ensure the nails in the magazine are aligned properly. If not, adjust them for even spacing and alignment.

  2. Inspect Driver Blade Spring: If the driver blade spring is worn or weak, replace it to provide the necessary force for a single nail drive.

  3. Adjust Air Pressure: Ensure your air compressor is set to the manufacturer’s recommended pressure for the specific nail size and material you’re working with.

  4. Depth Adjustment: Set the depth adjustment correctly to prevent nails from being driven too deep into the material.


The brad nailer shooting two nails might seem like a peculiar quirk, but it’s a phenomenon that can be managed with the right knowledge and troubleshooting. While it may occasionally work to your advantage, in most cases, it’s essential to maintain your nailer, ensuring it delivers the precision and performance you rely on. By understanding the causes and taking appropriate measures, you can continue to craft with the finesse and accuracy that make the brad nailer an indispensable tool in your woodworking arsenal.
