Description
Tex 210 performance is supported by NEXUS tensile test data, giving you measured information to evaluate strength and elongation before choosing the thread for your project.
Tex 210 Bonded Nylon Thread
Tex 210 bonded nylon thread (#207 / 630D/3) is made from bonded nylon 6.6 and is designed for heavier machine-sewn applications. Its larger thread size creates a stronger, more prominent stitch for heavy leather, canvas, webbing, upholstery, heavy-duty bags and similar thicker assemblies. The bonded construction helps improve thread handling during sewing, while the heavier profile makes Tex 210 a better choice when lighter thread sizes do not provide the desired seam strength or stitch appearance.
How Tex 210 (630D/3) Bonded Nylon 6.6 Performs
Tex 210 (630D/3) bonded nylon 6.6 is a heavier thread size designed for machine-sewn applications where a stronger, more prominent stitch is required. Its performance can be supported by NEXUS tensile test data, while the larger thread size gives projects a more substantial stitch appearance than lighter thread options.


Best Applications for Tex 210 Bonded Nylon Thread
- Heavy Leather & Saddlery: Suitable for saddles, harnesses, heavy leather tool bags and other thick leather assemblies where a larger, more visible stitch is preferred.
- Heavy Canvas & Covers: A practical choice for canvas covers, tarpaulins and other heavier fabric constructions.
- Webbing & Straps: Suitable for heavy webbing, cargo straps and similar assemblies that require a substantial machine-sewn seam.
- Heavy-Duty Bags & Cases: Works well for tool bags, equipment bags and rigid cases made from thicker materials.
- Industrial Upholstery: Suitable for heavier upholstery assemblies where lighter thread sizes may not provide the desired stitch size or seam strength.
How to Use Tex 210 Bonded Nylon Thread
- Machine Setup: Use a heavy-duty or industrial sewing machine that can properly handle Tex 210 thread and thicker materials.
- Needle Size: Start with a needle around Nm 140/22 to Nm 180/24, then adjust according to the material thickness, machine setup and stitch result.
- Thread Tension: Adjust upper and bobbin tension gradually until the stitch is balanced and the thread feeds smoothly.
- Material Testing: Test the thread, needle and tension on scrap material before sewing the final project.
- Stitch Appearance: Because Tex 210 creates a larger, more prominent stitch, check stitch spacing and appearance on the actual material before production.
- Machine Compatibility: Confirm that the machine, needle system and bobbin setup can accommodate Tex 210 before sewing.


Why Choose Tex 210 Bonded Nylon Thread
- Heavier Thread Size: Tex 210 creates a larger, more visible stitch than lighter thread sizes, making it suitable for thicker materials and more substantial seams.
- 630D/3 Construction: The 630D/3 size gives Tex 210 a distinctly heavier profile for machine-sewn applications.
- Stronger Seam Capability: NEXUS tensile test data supports Tex 210 as a higher-strength option for applications that demand more from the seam.
- Better Fit for Heavy Materials: A better choice when Tex 135 is too light for the material, stitch appearance or seam requirement.
- Machine-Sewing Focus: Designed for machine sewing where the equipment, needle and tension setup can properly accommodate a heavier thread.

Test results are NEXUS internal tensile testing of the tested sample under the stated conditions and may vary slightly by production batch and test conditions.
Choose and Verify Your Thread Color
Compare the available Tex 210 color options and choose the shade that best fits your material and project. Because screen settings and lighting can affect how colors appear online, NEXUS provides pre-shipment photo verification so you can review the actual product and color before it ships.


Tex 210 Thread Size, Needle & Machine Guide
- Thread Size: Tex 210 (#207 / 630D/3) is a heavier bonded nylon thread for machine-sewn applications that require a larger, more visible stitch.
- Recommended Needle Range: Start around Nm 140/22 to Nm 180/24, then adjust according to material thickness, machine setup and stitch result.
- Machine Type: Best suited to heavy-duty or industrial sewing machines that can properly handle Tex 210 thread.
- Material Fit: Better suited to heavier leather, canvas, webbing, upholstery and similar thicker assemblies than lighter thread sizes.
- Setup Check: Confirm that the machine, needle system, bobbin and tension setup are compatible with Tex 210 before final sewing.
Tex 135 vs Tex 210: Which Thread Size Should You Choose?
| Feature | Tex 135 | Tex 210 |
|---|---|---|
| Thread Profile | Medium-heavy | Heavier |
| Stitch Appearance | Strong and visible | Larger and more prominent |
| Material Fit | Leather goods, bags, upholstery, canvas | Heavy leather, heavy canvas, webbing, heavy-duty bags and similar thicker assemblies |
| Machine Requirement | Heavy-duty / industrial machine | Heavy-duty / industrial machine with setup suitable for heavier thread |
| Best Choice When | You need strength without an oversized stitch | You need a more substantial stitch and heavier thread size |
Choose Tex 135 when you need a strong, visible stitch without moving to a heavier thread size. Choose Tex 210 when the material, seam requirement or stitch appearance calls for a larger and more substantial thread.
