Turpai LWX6T Needle Guide: How to Pick the Right Sewing Needle

By Aashu, owner of Stitch Partner, a store for sewing machine needles and spare parts in India.

Find your needle system first

Needles are made in different systems, and the wrong one will not fit or sew properly. The system is usually printed on the old needle's packaging or stamped on the needle itself. If you are unsure, check your machine manual or bring the old needle to compare.

What the size number means

The size number relates to the diameter of the needle blade. Finer fabrics generally suit a smaller number, and thicker fabrics a larger one. Match the needle to both your fabric and your thread.

Fitting a needle correctly

  1. Switch off the machine.
  2. Loosen the needle clamp screw and remove the old needle.
  3. Insert the new needle fully up into the needle bar, with the orientation shown in your machine manual.
  4. Tighten the screw firmly, then turn the handwheel by hand to confirm it clears the plate and foot.

Frequently asked questions

How do I know which needle system my machine takes?

Check the manual or the needle currently fitted, because the system is printed on the needle pack. If unsure, send the machine model and a photo of the needle to Stitch Partner before ordering.

How often should I change the needle?

Change it when it is bent or blunt, after any needle strike, or when stitch quality drops. In heavy daily use many workshops change needles at a regular interval.

What does the size number mean?

It is the thickness of the needle shaft. Use a thicker needle for heavy fabric and thread, and a finer needle for light fabric.

Why does the needle break at the same spot?

It is usually hitting the needle plate, the presser foot or the hook. Check that the needle is fully seated and straight, and check the plate and foot position.
