Add strong, heavy-duty seams with Coats NylBond Z-Twist Nylon Thread in Tex 135. Black delivers a deep, true black that blends seamlessly with dark webbing, leather, and heavy fabrics or creates striking contrast on light materials, keeping stitch lines consistent and sharp on thick, demanding projects. Bonded nylon construction delivers reliable sewing where high tensile strength and steady performance matter on thick layers, dense materials, and rugged projects. Z-twist construction matches the standard twist direction for most lockstitch sewing machines, helping the thread stay intact through the stitch cycle for smoother sewing and fewer breaks.
Rely on clear specs for efficient setup. This bonded nylon thread is Tex 135, a heavy-weight profile suited for bold, durable stitching on thick webbing, multiple fabric layers, and heavy-duty materials. Packaging includes a 16 oz spool, providing generous yardage for larger runs, repairs, and project batches without frequent spool changes. It fits heavy-duty commercial and industrial machines built for thicker thread; most standard home machines aren't suited to this weight. Test on scrap material to dial in needle size, tension, and stitch length.
Put this bonded nylon to work on tactical gear, heavy bags, straps, webbing, leatherwork, outdoor equipment, and upholstery where black stitching delivers a bold, finished look. Avoid using thread for load-bearing or safety-critical applications, such as climbing, lifting, towing, or restraint. For best results, use steady speed, correct tension, and a clean thread path to reduce friction and skipped stitches.
