316 Stainless Steel Tangless Coilthread Wire Threaded Repairing Inserts are cost-effective and reliable fasteners that create strong and durable threads in soft or low-strength materials. They have no tang to break off or retrieve, making them easy and convenient to install and remove. Ideal for applications requiring fast installation in aluminium or aluminium alloys.
These inserts provide excellent thread performance, corrosion resistance, and wear resistance. Designed to be installed in molded or drilled holes in one simple step, they typically strengthen threads and protect tapped holes against failure, prolonging application life.
