Having trouble with yarn slipping or getting stuck in your tufting gun? One of the most common issues for both beginners and experienced tufters is the size of the needle hole — especially when switching between thick and thin yarn. In this quick guide, we’ll show you exactly how to adjust the needle hole on your AK-V or AK-1 tufting gun so it works perfectly with any yarn type.

Why Adjust the Needle Hole?
The needle hole in a tufting gun controls how freely your yarn passes through. If it's too tight, your yarn may get stuck or break. If it's too loose, thinner yarns can fall out or fail to punch cleanly. That's why it's important to adjust it based on the yarn size you're using.
What You'll Need
- A small allen key(typically included with your tufting gun)
- Your AK-V or AK-1 tufting gun
- The yarn you plan to use
Step-by-Step: How to Adjust the Needle Hole
Step 1: Prepare Your Tools
Unplug your tufting gun and place it on a stable surface. Have your screwdriver and yarn ready.
Step 2: Locate the Allen Screw
Find the small screw located at the top of the needle shaft. This screw holds the internal metal tension plate in place — it’s what determines the size of the needle hole.
Step 3: Loosen the Screw
Using your Allen key, gently loosen the screw. Do not remove it completely — just loosen it enough so the plate inside can move up or down.
Step 4: Flip the Gun and Adjust
Turn the tufting gun upside down to get a clear view of the black metal plate inside the needle. Use the screwdriver or your finger to move this plate:
- Push the plate down → to widen the hole for thick yarn
- Push the plate up → to tighten the hole for thin yarn
Step 5: Test With Yarn
Insert your yarn through the needle to check the fit. It should slide in easily, but not fall out when you tilt or move the gun.
Step 6: Tighten and Secure
Once you’re happy with the fit, tighten the screw again to lock the plate in place. That’s it — your needle is now adjusted for perfect tufting!
Tips for Best Results
- Always test on scrap fabric before starting your real rug.

FAQs
1. Do I need to adjust the needle hole for every yarn?
Not always. If you use the same yarn size regularly, you can keep your setting. But if you switch between chunky and fine yarn, adjustment is recommended.
2. Can adjusting the hole damage the gun?
No — the gun is built for this. Just be gentle with the screw and avoid forcing the metal plate.
3. What if my yarn still won’t flow?
Try lubricating the needle with a drop of machine oil, or trim any fuzz from the yarn. Also check for lint buildup inside the needle.
4. How tight should the hole be for thin yarn?
The yarn should slide in easily but stay in place if you tip the gun slightly down. That’s usually the sweet spot.
5. Can I use this guide for other tufting gun models?
This guide is specifically for AK-V and AK-1 models. Other guns may have a different needle design.
6. Where can I buy yarn that fits my gun?
You can find compatible yarn and accessories directly in our Yarn & Cloth section.
