Position components in assemblies, as well as separate or connect parts with these standoffs. The flat sides of the hex ensure a firm grip when tightening with a wrench.

Aluminum standoffs are lightweight, nonmagnetic, and mildly corrosion resistant. Material can vary between 6061 and 2011 aluminum.

Zinc-plated brass standoffs are electrically conductive, nonmagnetic, and have a corrosion-resistant finish.

Nylon standoffs have excellent wear and abrasion resistance and also offer resistance to chemicals and solvents (except mineral acids). Exposure to moisture may cause them to expand.

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.

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. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.

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.

With a distorted internal thread and keys on the outside, these inserts create a strong hold on both fasteners and surrounding material. Together, the distorted thread and keys create a mechanical lock that resists pull-out from vibration or temperature changes and is stronger than inserts that require threadlocker. Use them to create completely new threads, add strong threads in soft metal, or replace existing threads that are damaged or need to be resized. They're often seen in molds, tools and dies, and suspension systems in vehicles.

Made of a solid piece of metal, these inserts are also stronger than helical inserts, which are made of coiled wire. A dry-film lubricant makes it easy to install them and to screw fasteners into them. All are made to tight tolerances with strictly controlled materials; many inch sizes also meet military or aerospace standards for dimensions and material.

To install, you'll need a tap to create the threads in your material, and an installation tool and a hammer to drive the keys into the material.

When choosing between stainless steel and cadmium-plated steel, consider strength and price. Both materials withstand wet environments. Stainless steel inserts are economical, but not as strong as steel. Use cadmium-plated steel inserts in applications where additional strength is necessary, such as in engine blocks. Steel inserts are stronger than stainless steel inserts, but are more expensive.

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

The flange keeps these inserts from pulling through a hole. Install on the underside of the material by pressing them into a drilled hole. Install a screw to expand the insert and drive the knurls into the surrounding plastic to keep it from pulling out. Made from brass, they’re nonmagnetic, corrosion resistant, and electrically conductive. Installed length includes the flange.

Use these inserts to install fine-threaded screws in existing holes. Made from brass, they’re corrosion resistant, electrically conductive, and nonmagnetic. Press them into a drilled hole.

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.
