Strong where everyday thread may be too light
Extra Strong combines a strong polyester core with a textile outer surface. Mettler designed it for excellent sewability, high tear resistance and abrasion resistance, making it a practical choice when seam durability and visible stitch definition both matter.
Abrasion resistant
Well suited to seams exposed to rubbing, movement and regular handling.
Bold topstitching
The heavier thread profile gives decorative stitching and seam detail more presence.
Hand-sewing strength
A useful choice for firmly sewing buttons and completing strong repairs by hand.
A versatile problem-solver
From denim repairs to decorative detail
Keep Extra Strong ready for projects where a finer construction thread does not give the look or durability you want. The 125m spool is compact, easy to store and generous enough for repairs, garment details and focused heavy-duty sewing tasks.
Denim and workwear
Repair seams, reinforce high-use areas and add strong visible stitching to compatible fabrics.

Machine and needle guidance
Give the heavier thread room to form a clean stitch
Mettler recommends needle sizes Nm 90 to 120. Choose the actual needle size and point for your material, thread path and machine, then test the complete seam before sewing the project.
NeedleUse a fresh needle with an eye large enough for Extra Strong to pass without rubbing.
StitchA slightly longer stitch can show the heavier thread attractively in visible topstitching.
TestSew through the actual number of layers and check both sides for balanced tension.
- Match the needle point to the material, such as denim, leather or another machine-approved type.
- Thread the machine carefully and confirm that the spool turns and feeds freely.
- Reduce stitch density if a tightly packed seam makes the thread build up.
- Use a suitable thread in the bobbin and balance the tension on a project offcut.
- For hand sewing, select a strong needle with an eye that accepts the thread comfortably.
Extra Strong or regular all-purpose thread?
The best choice depends on the seam. Extra Strong is intentionally heavier and more visible than a standard garment-construction thread.
