Helical Threaded Insert Installation and Prong Break-Off Tools
 |
T-Handle |
Install helical inserts and break off prongs with one tool and a hammer strike. These tools have a slot that grips your insert’s prong for turning both left- and right-hand threads. Slide an insert onto these tools and drive them a quarter-turn to half-turn below the material’s surface. Then, strike the end of the tool with a hammer to break off the prong. These tools work with pronged helical inserts.

Helical Threaded Inserts
 |
Pronged |
Restore, reinforce, or create threads in metal. 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.
Pronged—The prong attaches to an installation tool for precise control as you drive inserts in. Remove the prong with a punch or break-off tool before inserting a screw.
18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.
