Understanding Tap and Drill Sizes
When it comes to tapping a hole for a 6-40 screw, understanding tap and drill sizes is crucial for a successful DIY project. Here’s a breakdown to help you navigate this aspect effectively:
Tap Size
Tap sizes are designated by a number followed by a hyphen and the number of threads per inch. For a 6-40 tap, the “6” indicates the size of the screw, while “40” refers to the number of threads per inch.
Drill Bit Diameter
To determine the right drill bit size for a 6-40 tap, you need to choose a drill bit slightly smaller than the tap size. For a 6-40 tap, the ideal drill bit size is typically #35. This drill bit ensures that the threads of the screw will grip securely while allowing for smooth tapping.
Matching Tap and Drill Sizes
Matching the tap and drill sizes accurately is essential for creating clean, precise threads. Using the correct drill bit size ensures that the tap can smoothly cut into the material without causing damage.
Practical Tip
Before starting the tapping process, it’s advisable to use a center punch to mark the center of the hole accurately. This small step helps the drill bit stay centered and prevents it from wandering during drilling.
Summary
Understanding tap and drill sizes is fundamental for the success of your project. By choosing the right drill bit size for a 6-40 tap, you’ll ensure that your screws fit securely and the threads are clean. Remember to match the tap size with the corresponding drill bit size for optimal results.
Equip yourself with this knowledge, and you’ll tackle your DIY tasks with confidence and precision.

Step-by-Step Guide on Drilling for a 6-40 Tap
When it comes to drilling for a 6-40 tap, following a precise process is crucial for achieving clean threads and a secure screw fit. Here’s a step-by-step guide to help you effectively drill for a 6-40 tap in your DIY projects:
1. Gather Your Tools:
Before starting, ensure you have the necessary tools handy:
- Drill press or a handheld drill
- Center punch
- Recommended drill bit size for a 6-40 tap – #35
2. Mark the Drilling Spot:
Using the center punch, mark the center of the hole where you plan to tap. This step is essential for accuracy in drilling and ensures your tap will go in straight.
3. Secure Your Workpiece:
Clamp down your workpiece securely to prevent any movement during the drilling process. Stability is key to achieving precise and clean results.
4. Attach the Drill Bit:
Insert the #35 drill bit into your drill press or handheld drill. Make sure it’s securely in place and straight to avoid any issues during drilling.
5. Start Drilling:
Position the drill bit over the marked spot on your workpiece. Start drilling at a slow and steady pace to ensure accuracy. Apply gentle pressure without forcing the drill bit through the material.
6. Check Depth:
Monitor the depth of your drilling to match the requirements of the 6-40 tap. Stop drilling once you reach the appropriate depth for tapping the hole.
7. Clean the Hole:
After drilling, remove any debris or metal shavings from the hole to prepare it for tapping. A clean hole ensures smooth threading when using the tap.
8. Ready for Tapping:
Your drilled hole is now ready for tapping with the 6-40 tap. Proceed with tapping the hole following the manufacturer’s instructions for the tap you’re using.

Common Mistakes and How to Avoid Them
To ensure a smooth and successful tapping process for a 6-40 screw, it’s essential to steer clear of common errors that could hamper your DIY project. By understanding these pitfalls and knowing how to sidestep them, you’ll enhance the quality of your threaded holes and screw fits.
Incorrect Drill Bit Size Selection
One prevalent mistake is using the wrong drill bit size when preparing for a 6-40 tap. If the drill bit size is too small, you risk not achieving the required thread depth, leading to weak connections. Conversely, using a drill bit that’s too large may result in loose threads that compromise the integrity of the screw hold.
Avoidance Tip: Always refer to a drill bit size chart specifically designed for tapping operations. Select the recommended drill bit size, in this case, a #35 bit, to ensure precise threading and a secure fit for your 6-40 screw.
Lack of Depth Control
Drilling to the correct depth is crucial for accommodating the entire tap and creating threads that securely hold the screw in place. Failing to control the drilling depth can result in shallow threads, making the connection prone to stripping or loosening over time.
Avoidance Tip: Utilize depth markers on the drill bit or set a stop collar on the drill to ensure consistent and accurate drilling depths for the 6-40 tap. Confirm the required depth before drilling to guarantee a robust thread engagement.
Inadequate Cleaning of the Hole
Neglecting to clean the drilled hole thoroughly before tapping can lead to debris accumulation, hindering the smooth threading process. Residual particles or burrs left in the hole may impede the tap’s progress, resulting in irregular threads.
Avoidance Tip: Before tapping, use a deburring tool or a suitable cleaning implement to remove any debris or sharp edges inside the drilled hole. Ensure the hole is clean and free of obstructions to facilitate effortless threading with the 6-40 tap.
By avoiding these common mistakes and following the recommended tips for precise drill bit selection, depth control, and hole cleaning, you’ll elevate the quality of your threaded holes for 6-40 screws in DIY projects. Stay attentive to these key aspects to achieve professional results and sturdy screw fits in your woodworking or metalworking endeavors.
