How to Install Helical Inserts

About Helical Insert Length

The tapered shape makes it easier to guide these inserts into a hole during installation. Use a drill bit to create a straight hole, then taper the top half. Heat inserts with a soldering tip so that they melt the plastic when installed. As the plastic cools, it solidifies around the knurls and ridges on the insert for excellent resistance to both torque and pull-out.

Made with lead, brass inserts are stronger than aluminum and other brass alloys but not as strong as 303 stainless steel inserts. They have good corrosion resistance.

303 stainless steel inserts are stronger than brass and aluminum inserts, have excellent corrosion resistance, and are lead-free. Since they’re lead-free, they can be safely recycled.

Inserts that meet ASTM standards comply with specifications for material quality.

Heat-Set Inserts for Plastic

Standard

Flanged

Install these inserts into plastic parts to create a secure base for fasteners. Also known as Chevron and headed inserts, they are often used to strengthen mounting holes on brittle plastics, such as on 3D printed parts. Unlike plastic threads, which wear down with repeated use, these threads hold their shape over a long life. Press inserts into straight holes that have been drilled, printed, or molded into plastic parts, then heat them with a soldering tip to melt the surrounding plastic. As the plastic cools, it fuses to the sharp, diagonal ridges around the inserts, which withstand torque and prevent the inserts from being pulled out. The interior is fully threaded, so you can access the threads from both sides of a through-hole.

Flanged inserts have a wider end than standard inserts, which gives them a larger load-bearing surface and makes them harder to pull out. The flange also gives you a larger contact area for soldering. When threading into the flanged side, these inserts prevent over-tightening, which can cause brittle plastic to crack.

Made with lead, brass inserts are stronger than aluminum and other brass alloys but not as strong as stainless steel inserts. They have good corrosion resistance.

Aluminum inserts are 70% lighter than brass and stainless steel inserts, have good corrosion resistance, and are lead-free. Since they’re lead-free, they can be safely recycled.

Stainless steel inserts are stronger than brass and aluminum inserts, have excellent corrosion resistance, and are lead-free. Since they’re lead-free, they can be safely recycled.

Male Threaded Heat-Set Inserts for Plastic

With the male threaded end on these inserts, mount components directly to plastic parts. The other end has two bands of diagonal knurls that face opposite directions to resist torque and pulling out. Heat the inserts on a hot plate, then press the knurled end into a straight hole. The heat melts the surrounding plastic, and as it cools it hardens around the knurls.

Compared to 3D printed or other plastic male threads that wear down when used over and over, these inserts are brass, which create a stronger fastening base. Brass is also corrosion resistant, nonmagnetic, and can be used as an electrical contact.

18-8 Stainless Steel Key-Locking Inserts

Made of stainless steel, these inserts have good corrosion resistance. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. Use them to repair or change threads in soft metals such as aluminum. Inserts may be mildly magnetic. They’re comparable to Keensert® inserts. Installation requires a drill bit, a standard tap, an installation tool, and a hammer.

Inserts with a thin wall are often used in small holes or near the edge of a workpiece.

Screw-Locking Key-Locking Inserts

Stainless Steel

Cadmium-Plated Steel

Forming the strongest hold of any of our threaded inserts, these inserts have a distorted internal thread to lock screws into place and keys that drive into surrounding material to prevent slipping and rotating. This creates a mechanical lock, which is stronger than the chemical lock from adhesive on thread-locking inserts. Because they’re made of a solid piece of metal, these inserts are also stronger than helical inserts, which are made of coiled wire. They're often used in molds, tools and dies, and suspension systems in vehicles to create completely new threads, add strong threads in soft metal, or replace existing threads that are damaged or need to be resized.

A dry-film lubricant makes it easy to install them and screw fasteners in. To install, use a tap to create the threads in your material and an installation tool to drive the keys into the material. All are made to tight tolerances with strictly controlled materials. Many inch sizes also meet military or aerospace standards for dimensions and material.

These inserts resist corrosion in wet environments. Cadmium-plated steel inserts are stronger than stainless steel inserts.

Inserts with thin walls are best for small holes or near the edge of a workpiece. They’re often used in electronics that require small fasteners.

Stainless Steel Helical Inserts

Also known as Heli-Coil inserts, these inserts have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.

Inserts that meet DIN 8140 adhere to international standards for dimensions.

Stainless Steel Helical Inserts for Particle-Free Environments

Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw.
