Speedway 100% Spun Polyester Sewing Thread Tex 27 (40/2) — 2,500 m Cone for Short Runs

Speedway Tex 27 spun polyester is the general-purpose garment-industry sewing thread; this is the 2,500 m cone, the same thread as our 5,000 m production cone in half the put-up. This is the one for short runs, sampling rooms, repairs and alterations: colours you use occasionally and would rather not commit a full production cone to, and a cone that does not outlive the job. Five colours. Ships from Miami, FL.

Technical Specifications

What is it used for?

• Sampling rooms and short production runs
• Alterations and repair work, where a colour gets used once and then sits
• Overlock and coverstitch on accent colours
• Home and small workshops with limited thread storage

What needle size should I use?

Use a Nm 70–80 (Singer 10–12) needle with this thread.

That is the size. The system — DBx1, 135x17, 134-35 — depends on your machine, not on the thread. How to identify yours · Industrial machine needles

Careful with “Nm”: for thread it means 1000/Tex (Tex 27 = Nm 37.0), but for needles it means the blade diameter in hundredths of a millimetre (Nm 110 = 1.10 mm). They are not the same number. Conversion formulas from Coats; government sizes from the A-A-59826 specification published by American & Efird.

Not sure between two sizes?

Tex 27 or Tex 60? Tex 27 is the garment-industry default. Move to Tex 60 when you want the stitch to show, or when the material is heavier than mid-weight.

Bonded Nylon vs. Spun Polyester — which one?

Bonded nylon is stronger for its diameter and more abrasion resistant, and the bonding agent keeps the plies from fraying at high sewing speeds. It is the standard for upholstery, leather and canvas worked indoors or under cover.

Spun polyester holds up better to prolonged sunlight and moisture. For anything that lives outdoors year-round, polyester — or our UV-treated nylon — is the safer choice.

Frequently Asked Questions

What needle size should I use with Tex 27?

Nm 70–80 (Singer 10–12). If the stitch looks starved or the thread frays, go one size up before changing anything else.

Should I use Tex 27 or the next size?

Tex 27 or Tex 60? Tex 27 is the garment-industry default. Move to Tex 60 when you want the stitch to show, or when the material is heavier than mid-weight.

How many yards are on the cone?

This is a 2,500 m cone (2,734 yds). Metres and yards are an exact conversion, so that figure is not an estimate.

Will this work on a domestic machine?

Yes. Tex 27 is a normal garment weight — any domestic machine handles it with the needle size above. It is also the weight most overlock and coverstitch machines are set up for.
