Bonded Nylon Sewing Thread - Heavy-Duty (10s-60s)

Bonded Nylon Sewing Thread - Heavy-Duty Thread for Gear, Leather & Upholstery

Strong, bonded nylon sewing thread for building and repairing dog gear, luggage, upholstery, and footwear. Shiny, moisture-resistant, and chemically stable, it sews smoothly at high speed and in any direction, with high tensile strength for demanding seams.

Why choose bonded nylon

Bonded nylon is one of the strongest general-purpose threads available. The bonding resists fraying and abrasion, making it a favorite for heavy materials and load-bearing stitching. For safety-critical load restraint, always pair it with rated hardware and webbing.
