Tools You Will Need

  • Wire cutters
  • Hammer
  • Measuring tape or ruler

Step-by-step Instructions for How to Cut Screws for Knobs

Step 1: Inspect the Screw

Before cutting any screw, it is important to inspect it in order to determine its type and size. Screws come in different sizes and shapes and knowing these details will help you choose the right tool for cutting.

Step 2: Gather Tools and Materials

Once you have determined the type and size of the screw, gather all the necessary tools and materials for cutting. This may include a hacksaw, pliers, or a rotary tool with a cutting wheel attachment. You will also need safety goggles to protect your eyes from flying debris.

Step 3: Measure and Mark the Screw

Use a ruler or tape measure to determine the length you want to cut the screw. Make a small mark with a pencil or marker at this point on the screw so that you know where to cut. Place the screw in a vice or clamp it down to a stable surface. This will prevent the screw from moving while you are cutting it and ensure an accurate cut.

Step 4: Cut off the Excess Length

Using the appropriate tool, carefully cut off the excess length of the screw at your marked point. If you are using a hacksaw, use long, steady strokes to avoid bending or breaking the screw. After cutting, you may notice that the end of the screw is rough or jagged. Use a metal file or sandpaper to smooth out the cut end and remove any sharp edges.

Step 5: Check the Fit

Once you have smoothed out the cut end, test the fit of your knob on the screw. If needed, use pliers to adjust the shape of the cut end so that it fits properly into your knob. Before attaching your knob, it is important to clean off any debris or metal shavings from the screw. Use a brush or compressed air to remove any particles that may interfere with the fit of your knob.

Step 6: Attach the Knob

With your screw now properly cut and cleaned, you can attach your knob to the end. Simply screw it on until it is secure. Once your knob is attached, check that it is securely in place by gently pulling or twisting it. If everything looks good, congratulations! You have successfully learned to cut screws for knobs. Now go ahead and use this skill to complete your project with precision and ease.

Tips for How to Cut Screws for Knobs

  1. Cutting screws requires specialized tools like a hacksaw, bolt cutter or angle grinder. Make sure to use the right tool for the type and size of screw you are cutting.
  2. It is important to wear safety gear such as gloves and goggles while cutting screws. This will protect your hands from sharp edges and your eyes from flying debris.
  3. Before cutting the screws, ensure that they are securely clamped to a workbench or held in a vise. This will prevent them from slipping and causing injury.
  4. Measure and mark the screw at the desired length before cutting it. Use a ruler or measuring tape to get an accurate measurement.
  5. Make sure the cutting tool is sharp before starting the process. Dull blades can cause accidents and make it difficult to cut through the screw.
  6. Avoid applying too much pressure while cutting the screw, as this can cause the tool to slip and potentially injure you. Let the tool do the work and use steady, controlled movements.
  7. After cutting the screw, use a file or sandpaper to smooth out any rough edges. This will not only prevent cuts and injuries but also help the screw fit better into the knob.

Is There Any Risk of Damaging the Knob When Cutting the Screw?

While cutting screws for knobs, it is essential to ensure the safety of yourself and your surroundings. Additionally, there are a few precautions that you can take to avoid damaging the knob during the cutting process:

 Avoid Damaging the Knob During the Cutting
  • Place a cloth or protective cover over the surface of the knob before clamping it down to prevent any scratches or marks.
  • If possible, use a vise that has rubber or plastic jaws to hold the screw in place securely without damaging it.
  • Use a cutting tool with a fine-toothed blade to ensure clean and precise cuts without damaging the screw or knob.
  • If you are using an angle grinder, make sure to use it at a low speed to prevent any damage to the knob due to excessive force. Additionally, secure the knob in place while cutting by holding it down with your non-dominant hand.
  • If you are using a hacksaw, make sure to use slow and even strokes while cutting the screw to avoid any accidental damage to the knob.
  • After cutting the screw, carefully remove it from the vise and inspect both the screw and knob for any signs of damage. If there is any visible damage, consider replacing the knob or using a different cutting method in the future.

By following these safety tips and precautions, you can ensure a clean and precise cut while also protecting the knob from any potential damage. Remember to always prioritize safety and take your time when cutting screws for knobs to avoid accidents.

What Are Some Common Mistakes to Avoid When Cutting Screws for Knobs?

When it comes to installing new knobs on your furniture or cabinets, you may need to cut the screws in order for them to fit properly. However, cutting screws is not as straightforward as it may seem and can actually be quite tricky if you don’t know what you’re doing. In this section, we will discuss some common mistakes to avoid when cutting screws for knobs and provide you with some tips to help make the process easier.

1. Using the Wrong Tools

One of the biggest mistakes people make when cutting screws for knobs is using the wrong tools. While a regular pair of pliers or wire cutters may seem like they can get the job done, they are not ideal for this task. Instead, you should use a pair of bolt cutters or a hacksaw to cleanly and accurately cut your screws. These tools are designed specifically for cutting metal and will provide you with a much smoother and more precise cut.

2. Not Measuring Properly

Another common mistake is not measuring your screws properly before cutting them. It’s important to measure the length of the screw that you will need in order for it to fit snugly into your knob and furniture. Make sure to leave enough room for the screw to go into both the knob and furniture, but not so much that it sticks out too far. This can cause the knob to be loose or even prevent it from fitting altogether.

3. Not Securing the Screw Properly

When cutting screws, it’s important to secure them properly so that they don’t move around while you are trying to cut them. This can result in an uneven and jagged cut, which will make it difficult for your screw to fit into the knob properly. To avoid this mistake, use a vise or clamp to hold the screw steady while you cut it with your chosen tool.

4. Not Deburring the Cut End

After cutting your screws, it’s important to deburr the cut end. This means removing any rough or sharp edges that may have been created during the cutting process. These edges can not only be unsightly, but they can also make it difficult for your screw to fit into the knob properly. Use a file or sandpaper to smooth out and deburr the cut end before attempting to install your knob.

Tip: Use Lubricant

Cutting screws can be a tough job, especially if you are working with harder materials such as stainless steel or titanium. To make the process easier and prevent damage to your tools, consider using a lubricant such as WD-40 while cutting your screws. This will help reduce friction and make it easier for your chosen tool to cut through the metal.


In conclusion, there are several common mistakes to avoid when cutting screws for knobs. By using the right tools, measuring properly, securing the screw, deburring the cut end, and using lubricant, you can make this task much easier and ensure a clean and precise cut. With these tips in mind, you will be able to successfully install new knobs on your furniture or cabinets without any trouble.

Remember to always take your time and be patient when cutting screws – it’s better to take a few extra minutes to do it correctly than rush through and end up with a botched job.
