Offered in a generous 800-yard spool, the Size 207 (630D T210) thread is formulated to withstand abrasion, higher temperatures than polyester, and exposure to sunlight and moisture—making it suitable for both workshop and industrial sewing machines, sergers, and hand stitching. The nylon is coated with a colourfast bonding agent for consistent feed through needles and reliable, durable seams.\u003c\/p\u003e\n\n\u003ch3\u003eHow strong is this thread for heavy materials?\u003c\/h3\u003e\n\u003cp\u003eThe 630 denier (Size 207) and T210 construction deliver high tensile strength appropriate for demanding applications.
