Description
Built for Heavy-Duty Machine Sewing
Tex 270 combines a very heavy 840D/3 thread profile with measured tensile performance for demanding machine-sewn applications.
Tex 270 (#277 / 840D/3) Bonded Nylon Thread
Tex 270 (#277 / 840D/3) bonded nylon 6.6 is one of the heavier thread sizes in the NEXUS bonded nylon range. It is intended for machine-sewn projects using thicker materials where a substantial seam and highly visible stitch are required.
How Tex 270 (840D/3) Bonded Nylon 6.6 Performs
Tex 270 (840D/3) bonded nylon 6.6 provides a heavier thread profile for demanding machine-sewn applications. Its larger size creates a substantial stitch and is intended for projects where lighter thread sizes may not provide the desired seam strength or stitch appearance. NEXUS tensile test data can be used to evaluate its measured performance before selection.
Best Applications for Tex 270 Bonded Nylon Thread
- Heavy Leather & Saddlery: Suitable for thick leather assemblies where a very substantial machine-sewn stitch is required.
- Heavy Canvas & Covers: Suitable for heavier canvas constructions, covers and similar thick fabric assemblies.
- Heavy Webbing & Straps: A useful option for thick webbing and strap assemblies that require a larger thread profile.
- Heavy-Duty Bags & Cases: Suitable for equipment bags, tool bags and cases made from thicker materials.
- Industrial Upholstery: Can be considered for heavier upholstery work where a large stitch and heavier thread size are preferred.

Tex 270 is a very heavy thread size and may be larger than necessary for many leather goods, bags and upholstery projects. Choose Tex 210 when you need a heavy stitch with less bulk, or Tex 135 when the project requires a strong but more moderate stitch profile.
How to Use Tex 270 Bonded Nylon Thread
- Machine Setup: Use a heavy-duty or industrial sewing machine capable of handling a very heavy thread size.
- Machine Compatibility: Confirm that the machine, needle system, bobbin and thread path can accommodate Tex 270 before sewing.
- Thread Tension: Adjust upper and bobbin tension gradually until the stitch is balanced and the thread feeds consistently.
- Material Testing: Test the complete sewing setup on the actual material before beginning final production.
- Stitch Appearance: Check stitch length and spacing carefully because Tex 270 produces a large and highly visible stitch.
Why Choose Tex 270 Bonded Nylon Thread
- Very Heavy Thread Size: 840D/3 provides a substantially heavier thread profile than Tex 135 and Tex 210.
- Prominent Stitch Appearance: Creates a large, highly visible seam for projects where the thread is part of the finished visual design.
- Designed for Thick Materials: Better suited to applications where lighter thread sizes are too small for the material or desired seam profile.
- Measured Performance Available: NEXUS tensile test data provides measured information for evaluating thread performance.
- Machine-Sewing Focus: Intended for machine sewing with equipment properly configured for a thread of this size.
Tex 270 Thread Size & Machine Guide
- Thread Size: Tex 270 (#277 / 840D/3) is a very heavy bonded nylon thread for machine-sewn applications.
- Machine Type: Use equipment capable of handling very heavy thread and thick material assemblies.
- Material Fit: Best considered for thick leather, heavy canvas, webbing, heavy upholstery and similar substantial constructions.
- Setup Check: Confirm machine, needle system, bobbin capacity and tension compatibility before purchasing or sewing.
- Test Before Production: Always evaluate the full sewing setup on sample material before final production.
Choose and Verify Your Thread Color
Compare the available Tex 270 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 135 vs Tex 210 vs Tex 270: Which Size Should You Choose?
| Feature | Tex 135 | Tex 210 | Tex 270 |
|---|---|---|---|
| Thread Profile | Medium-heavy | Heavy | Very heavy |
| Stitch Appearance | Strong and visible | Larger and prominent | Large and highly prominent |
| Typical Material Fit | Medium-heavy materials | Heavy materials | Thick / very heavy materials |
| Choose When | You want strength without excessive bulk | You need a heavier seam and larger stitch | You specifically need a very heavy thread and substantial stitch |
Choose the thread size according to material thickness, seam requirements, machine capability and the stitch appearance you want. A larger thread is not automatically the better choice for every project.
