Best Serger Thread for Serger Machine 2024: Expert’s Review and Guide

Here are top 5 picks for the best serger thread of different materials - Polyester, Nylon & Cotton, and brands. Also a guide is included towards the end.

Threads used in sergers are quite different from normal sewing threads. This is what I realized after shifting from sewing to serging. And I discovered that these serger machines have specific requirements for threads and needles.

Serger thread is mostly used to secure the fabric’s edges, i.e. overlock, and create beautiful patterns on the fabric’s side. When compared to regular thread, it is more stretchy and stronger. The serger threads mostly include polyester and nylon, while cotton can be used but is not recommended. Among many serger threads available in the market, I have chosen the best serger threads that I have used.

Sewing with this thread is quite easy as it avoids uneven stitches, and you cannot see any bulky or smeared thread on the seam. It is ideal for securing the edges of fabric because of its strength and smoothness. It is typically used as an overlock thread on clothing. It holds the cloth in place and prevents the fabric’s regular stitches from falling out.

This is my favorite one to use in serger machines for small tasks because I prefer to do overlock and decorative edges at home. This thread has high tensile strength and comes in a wide range of colors, but unfortunately, you have to search for them individually. Nonetheless, Coats’ thread is one of my favorite choice of best serger threads.

I had to use cotton serger thread in one of my projects, and I used one of my favorite quilting threads. Surprisingly, it worked great on the serger. I also went through a lot of reviews on Amazone, and there were many who had recommended this for the serger.

American & Efird Maxi-Lock Serger Thread: Best Nylon Serger Thread

4.7/5 Our Score


  • Material: Nylon
  • Color: Balck
  • Number Of Pieces: 1
  • Length per piece: 135 Yards
  • Variations: Variety of other colors.

For swimwear, lingeries, sportswear, Sweaters, Sweatshirts, and other elasticized fabric, regular polyester or cotton threads are not suitable. I realized this the hard way. For that, I searched for different nylon and wooly nylon threads. And here is the best nylon serger thread I could find.

The most prominent feature of this nylon thread is that it can be stretched 15% to 30% before breaking. This is far more than any other nylon blend. Therefore, I like this thread so much, especially when it comes to sewing, seam, or overlocking elasticized fabrics.

Unlike cotton, it is rot-proof, and once sewn, it can survive for years without wearing out. It is even resistant to moisture. However, due to their stretchability, nylon threads are not as strong as others. Still, it is quite strong.

Why We Liked it
  • It does not rot over time.
  • Moisture resistant.
  • High elasticity and toughness.
  • Highly suitable for elasticized fabrics.
  • Great price value.
What we Disliked
  • Not thermal resistance.
  • Large color options are available, but they are needed to be searched individually.

I found it to be the most convenient thread for elasticized garments, yet at an economical price. Also, 2000 yards in length is sufficient for personal to professional usage. Thus making it one of the best nylon threads for serging.

Buyer guide

Before buying the best serger thread, you must know what the objectives of your project are and what kind of thread will be the best fit for it. If you buy the thread without doing any homework, you might waste your money and time on a thread that will eventually be useless for you.

So, you need to know some basic things that should be considered before buying a serger thread.


The serger thread is available in many materials like polyester, cotton, nylon, silk, and wool threads. So far, the best one is the polyester thread, and it is also a multipurpose thread that fits most of the stitching and sewing. However, other threads can also be used based on your preferences.


Another important factor of the serger thread to keep in mind is its durability. The thread must be strong, and when used on a fabric, it should last long without rotting or getting worn out. There are 2 and 3 ply threads available in the market, which are stronger than single-ply threads. Durability also depends on the material. So, choosing a good material, serger thread will also be durable.


Although price is secondary for me, I always prefer to focus on quality. But some people are cost-conscious too. So, even if you seek a low-cost thread, never compromise on quality. Several low-cost brands provide high-quality thread, so it is better to go for them.

Manufacturer Credibility

Many brands sell their threads in the market, but not all provide good enough threads. It is better to look for a brand that has a name in delivering high-quality, durable threads, long-lasting colors, and resistance to environmental factors. If you are new in this field and do not know much about it, you can ask someone who is an expert to guide you to the best available thread.

If you are struggling to thread a serger, here you can view our step-wise guide.



Based on their strength, usage, and compatibility, these are the best serger threads I have used. In the case of your project, the choice is yours. Before buying any thread, it’s better to note down your work demand and then choose accordingly. But it is always best to go for the thread that is durable and resistant to different environmental factors so it stays perfect for a long time.
