No lubricant means no mess or particles to contaminate environments such as clean rooms and labs. These inserts are made of Nitronic 60 stainless steel, which prevents sticking or binding that wears out the threads. They're ideal for parts that require frequent disassembly for inspection or repair. Also known as Heli-Coil inserts.

Installation requires a drill bit, a helical insert tap, and an installation tool.

The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration. Use these inserts to create or repair threads in pumps and other machinery that shakes and rattles. Also known as Heli-Coil inserts.

Installation requires a drill bit, a helical insert tap, and an installation tool.

Quickly restore stripped threads—these inserts come with through-hole taps and installation tools. The tough coils on these inserts expand once installed to anchor in a tapped hole.

Install prongless (tangless) helical inserts more quickly and consistently than with standard tools. These tools compress your insert’s diameter and align each coil with the thread pitch, guiding it straight into a tapped hole. They’re the best choice for preventing misaligned or damaged threads. Just make sure you have space to turn the crank. Screw an insert onto these tools and drive them a quarter- to half-turn below the material’s surface. Also known as prewinders.

Screws won't get stuck or come loose with these inserts. A dry film on the surface lubricates fasteners during insertion to prevent sticking and binding. Once installed, the irregularly shaped threads tightly grip screws to keep them in place under vibration. Also known as Heli-Coil inserts.

Installation requires a drill bit, a helical insert tap, and an installation tool.

Install and remove screws repeatedly without sticking or binding. These inserts have a dry-film lubricant on their surface for smooth installation. They're ideal for parts that require frequent disassembly for inspection or repair. Also known as Heli-Coil inserts.

Installation requires a drill bit, a helical insert tap, and an installation tool.

Remove prongless inserts without damaging threads or the surface of your material. These tools also back out or adjust inserts that are installed too deep.

Replacement Tips—Replacement tips (sold separately) come with one removal tip, two pins, and two springs.

Install standard and prongless helical inserts in high-volume production and assembly. Powered by compressed air, these tools deliver more force than electric tools. Use them to install a wide range of insert sizes. Press the lever to install the insert, then release to reverse out. These tools require a nosepiece and nosepiece adapter (both sold separately).

Install standard and prongless helical inserts faster than manual tools. These tools have an easy-start nosepiece to compress your insert’s diameter for smooth entry into tapped holes. Hold down the button to drive inserts—the tool then automatically reverses out of the hole. These tools require a nosepiece and nosepiece adapter (both sold separately).

Break the prong off of installed helical inserts. Place these tools inside the insert and hit the back with a hammer. Once removed, thread in your fastener.

Install standard and prongless helical inserts in tight spaces or where no power is available. Hold down the button to drive inserts more quickly than manual tools—the tool then automatically reverses out of the hole. Attach a nosepiece that matches your insert’s thread size.

An easy-start nosepiece compresses your insert’s diameter for smooth entry into tapped holes faster than manual tools. These tools install standard and prongless helical inserts in tight spaces or where power isn’t available. Hold down the button to drive the insert—the tool then automatically reverses out of the hole. These tools require a nosepiece and nosepiece adapter (both sold separately).
