Helical Threaded Inserts
 |
Prongless |
Restore, reinforce, or create metal threads. The tough coils on these inserts expand once installed to anchor in a tapped hole. Also known as Heli-Coil inserts, they're often used in engine heads and machinery housings where strong connections are critical. Unlike threadlocking inserts, you can remove and reuse them without them losing their strength.
Installation requires a drill bit, a helical insert tap, and an installation tool. Easy-start installation tools compress the diameter of your insert so it fits easily into a tapped hole. These tools are the best choice for preventing misaligned or damaged threads—just make sure you have space to turn the crank.
Prongless—Without a prong to break off and retrieve, these inserts save time and avoid leftover debris in holes.
18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.
