Efficiently Removing Twist Nails From Enclosed Trailers

how to remove enclosed trailer twist nails

Removing twist nails from an enclosed trailer can be a challenging task, as they are often difficult to extract. These nails, also known as hell nails or spiral shank nails, are commonly used in cargo trailer construction. When attempting removal, it's essential to identify the type of fastener involved, which could be a concrete nail, a screw nail, or even a screw with a unique head type, such as a Torx or double square drive. Proper identification is key to selecting the right tools and techniques for successful nail extraction without causing further complications.

Use a square drive

If you are removing nails from enclosed trailers, you may encounter square bit screws. A good, new square drive will work well to remove these. While Torx bits can work, they have six points, so they will only bite on half the screw interface and will strip about every other screw. Square bits have four points, so they can line up and grab every other point of an eight-point screw. You can also use a double square drive, which will bite on all eight sides of the screw.

If you are removing the interior plywood of your trailer, you may encounter curled Phillips head nails that you cannot screw out. In this case, you can use a pry bar to pop the plywood out or apply enough pressure to unscrew the nails. You can also try drilling the nail heads off, but this will still leave you with the shanks.

Square drives are also useful for removing the "hell" nails that fasten the plywood to the metal supports of cargo trailers. These nails have a Phillips head but are more like concrete nails.

If you are removing screws from a Forest River trailer, you may find that a square bit will work. However, these trailers also use Torx screws, so you may need to use a Torx bit instead.

Try a Torx bit

Removing twist nails from an enclosed trailer can be a challenging task, and choosing the right tools is essential. If you're dealing with spiral shank nails, screw nails, or "hell" nails, as they are often nicknamed, a Torx bit can be a viable option for removal.

Torx bits are star-shaped and designed to fit into the hole at the top of a Torx screw or bolt. When removing a twist nail with a Torx head, you'll need to select the appropriate size of Torx bit that matches the size of the nail head. Ensure you have a variety of sizes in your toolbox to accommodate different nail dimensions.

Once you've identified the correct size, insert the Torx bit into a drill. Place the bit firmly into the head of the nail, ensuring it sits securely in the centre. Start drilling slowly and with control to avoid slipping or damaging the surrounding material. Gradually increase the speed and apply gentle pressure to unscrew the nail.

In some cases, the nail head may be damaged or stripped, making it challenging to get a secure grip with the Torx bit. If this is the case, you may need to use a screw extraction kit, which typically includes various drill bits and extractor tools. Choose a drill bit that fits into the hole you've drilled into the nail head, and carefully attempt to reverse the nail out. Remember to work slowly and cautiously to avoid further complications.

Additionally, when dealing with stubborn or heavily fastened nails, it may be necessary to apply some form of lubrication, such as WD-40, to the nail and surrounding area. Allow the lubricant to penetrate the connection between the nail and the material before attempting to extract the nail with the Torx bit. This can help reduce friction and make the process smoother.

Drill out pop rivets

Drilling out pop rivets is a common method for removing them. The process can be done in several ways, depending on the tools available and the material of the rivets and substrate. Here is a step-by-step guide on how to drill out pop rivets:

Prepare the Rivet:

Before drilling, it is important to prepare the rivet for removal. One method is to use a punch to create a divot in the head of the rivet, providing a starter hole for the drill bit to grip onto. Alternatively, a die grinder can be used to grind the head of the rivet slightly, unlocking the post. This preparation step is especially useful if the rivet is stubborn and made of a hard material.

Choose the Right Drill Bit:

Selecting the appropriate drill bit size is crucial. A good rule of thumb is to choose a drill bit that is slightly larger than the rivet's shank or hole. This size will allow you to cut off the head or break it free once you drill through it. For example, if you are dealing with a 3/16" rivet, opt for a 1/4" drill bit. Additionally, consider using a drill bit with a V-point instead of a double-cutting point.

Drill the Rivet:

When drilling, it is essential to apply light pressure and let the drill bit do the cutting. Drill around the head of the rivet at a slight angle. This technique will cause the head to pop off or become easily removable. Once the head is removed, you can use a punch to drive the remaining part of the rivet through the hole. If needed, use a hammer with the punch for more force.

Protect Surrounding Materials:

If you are working with soft materials or surfaces that you want to protect, consider covering the area around the rivet with duct tape. This tape will help prevent the rivet from spinning and reduce the risk of damaging the surrounding material when drilling.

Final Thoughts:

Drilling out pop rivets is a straightforward process, but it requires some caution and the right tools. Always ensure your safety by wearing protective gear, such as gloves and eye protection, when handling power tools. Additionally, be mindful of the material and precision required for your specific project, as this may influence the techniques and tools you choose.

Use a square bit

Removing enclosed trailer twist nails can be a challenging task, but with the right tools and techniques, it can be accomplished effectively. One of the recommended tools for this job is a square bit. Square bits are commonly used in the trailer industry, especially for utility trailers, and can be highly effective in removing twist nails.

When using a square bit to remove enclosed trailer twist nails, it is important to select the correct size. The square bit should fit snugly into the head of the nail. If the bit is too small, it may not grip the nail securely, leading to slippage and potential damage to the nail head. On the other hand, a bit that is too large may not fit into the recess at all. Therefore, it is advisable to have a set of square bits in different sizes readily available to increase the chances of finding the perfect fit.

While a square bit can be used, it is important to note that it will only engage with half of the screw interface. This means that out of the eight points on the screw head, the square bit will only bite onto four of them. As a result, there is a high likelihood of stripping the screw, especially if the bit is not an exact fit. To mitigate this issue, it is recommended to use a double square bit, which has eight points and can engage with all sides of the screw head, reducing the chances of stripping.

To use the square bit effectively, it is essential to apply even and controlled pressure when attempting to remove the twist nails. Excessive force may lead to breakage or damage to the nail head, making the removal process more challenging. Additionally, the use of a pry bar in conjunction with the square bit can be beneficial. By carefully prying and levering the nails, you can create enough space to get the square bit in place and gain better access to the twist nails.

In some cases, the square bit may not be sufficient to remove all the twist nails, especially if they are heavily rusted or damaged. In such instances, it may be necessary to consider alternative methods or tools, such as drilling or using a different type of bit specifically designed for challenging fasteners. Overall, the square bit is a useful tool for removing enclosed trailer twist nails, but it may not always be the sole solution, and other techniques might need to be explored depending on the specific situation.

Replace with self-tapping screws

If you're looking to remove enclosed trailer twist nails, one option is to replace them with self-tapping screws. This method can be useful if you're finding it difficult to pull out the nails or if you're concerned about potential leaks.

Here's a step-by-step guide on how to replace your enclosed trailer twist nails with self-tapping screws:

First, you'll need to purchase the right type of self-tapping screws. For this application, you'll want to look for trailer deck screws that are specifically designed for attaching wood to metal. These screws are typically made of steel and feature a flathead design, allowing them to sit flush with the surface of the trailer. You can find these types of screws online or at your local hardware store.

Once you have the screws, gather the necessary tools, including a drill, a drill bit that matches the size of your screws (in this case, 7/32"), and a driver. Before you begin, it's important to inspect the trailer for any potential issues. Check the wiring, welds, and hitch attachment to ensure that everything is in order, as you don't want to overlook any cut corners.

Next, you'll start the process of replacing the nails with screws. Begin by drilling pilot holes where the nails are currently located. This will help guide the screws and make the process easier. After drilling the holes, you can then replace each nail with a self-tapping screw, using your drill and driver to fasten them securely. The self-tapping screws will lubricate and tap as you fasten them, creating a strong and secure hold.

By replacing the twist nails with self-tapping screws, you can achieve a smooth and even surface, which is crucial for safe and efficient loading and unloading of cargo. Additionally, these screws are designed to withstand harsh conditions, as they are coated with oil and feature a black phosphate finish for corrosion resistance.

Overall, replacing enclosed trailer twist nails with self-tapping screws is a detailed process that requires careful planning and execution. By following these steps and paying attention to safety, you can ensure a secure trailer for your journeys.
