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 thick walls are the most commonly used; they’re stronger than thin-wall inserts and are used in larger holes.

A black-phosphate finish provides mild corrosion resistance. Also known as E-Z Lok, these inserts use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours. Installation requires a drill bit and a standard tap. Then set the insert with a bolt and two nuts, or use an installation bit.

Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

To drive slotted inserts, you can use a slotted screwdriver instead of using an installation bit or a bolt and two nuts.

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.

Inserts come with a through-hole tap and installation tool. 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.

These nuts are chemical resistant and may be mildly magnetic. Also known as Allen nuts, use them with socket head cap screws in recessed holes and tight spaces that don't have enough clearance for a wrench. Tighten them with a 6-point hex key. They can also be used as an insert by pressing or drawing them into nonhardened steel, cast iron, or soft nonferrous metal or by molding them into plastic, ceramic, fiber, and similar materials.

Thread these mounts into machinery to level them on uneven floors in sanitary environments such as food-processing areas. They also create space to clean underneath machinery. All have a hygienic thread cover that prevents contaminants from settling in the grooves. To further block out contaminants as the mount moves, as well as prevent unsanitary metal-to-metal connections, there is a silicone seal at each end of the thread cover and at the point where the mount swivels. These seals have chemical additives, so you can find them with an X-ray machine if a piece falls into your line. This helps you comply with Hazard Analysis and Critical Control Point (HACCP) programs to keep contaminated food from leaving your facility. Seals are also FDA compliant for direct contact with food.

Made of 304 stainless steel, these mounts won’t corrode from frequent washdowns with harsh cleaners and sanitizers. Their smooth finish and rounded edges leave no crevices for bacteria to grow in, reducing the chance of foodborne illnesses. They also don’t have any horizontal ledges, so liquids and food will drain off completely. Certified by 3-A, EHEDG, and USDA, they meet sanitary design standards.

The rubber cushion on the bottom reduces vibration and noise from machinery, which protects floors and extends machine life. Their grip on the floor minimizes bacteria growth beneath them and prevents machines from shifting.

These mounts swivel to level machinery on slightly uneven floors; for severely uneven floors, use the threaded stud to raise each mount to a level height.

Some mounts have mounting holes to secure them to the floor, keeping machinery stationary. Mounts with one mounting hole are secure enough to prevent machines from moving while they’re running and being cleaned. Mounts with two mounting holes reduce vibration by anchoring machinery to the floor on both sides.
