Stainless Steel Helical Inserts without Prong
Without a prong to break off and retrieve, these inserts are often used where debris could cause damage. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. Installation requires a drill bit, a helical insert tap, and an installation tool.
Add an extraction tool to remove these inserts.

Lubricated Stainless Steel Helical Inserts without Prong
A dry film keeps the screw from sticking or binding in these inserts during installation. Without a prong to break off and retrieve, they are often used where debris could cause damage. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. Installation requires a drill bit, a helical insert tap, and an installation tool.

Screw-Locking Helical Inserts without Prong
A distorted thread grips the screw to resist loosening. Without a prong to break off and retrieve, these inserts are often used where debris could cause damage. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. Installation requires a drill bit, a helical insert tap, and an installation tool.
Inserts that meet DIN 8140 adhere to international standards for dimensions.
