These assortments include various sizes of thread-locking inserts. Also known as E-Z Lok, they use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours. All inserts have thick walls for strength and can be used to fill a large hole.

18-8 stainless steel inserts are more corrosion resistant than black-phosphate steel inserts.

Black-phosphate steel inserts are mildly corrosion resistant.

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.

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

A black-phosphate finish provides mild 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. They’re comparable to Keensert® inserts. Installation requires a drill bit, a standard tap, an installation tool, and a hammer.

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

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 18-8 stainless steel inserts.

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

Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. These inserts are used to repair or convert threads in soft metals such as aluminum. They’re comparable to Keensert® inserts.

18-8 stainless steel inserts are more corrosion resistant than black-phosphate steel. They may be mildly magnetic.

Black-phosphate steel inserts are mildly corrosion resistant.

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

For maximum mounting flexibility, cut the fully threaded shaft to whatever length you need. Also known as swing bolts and eyebolts, rod end bolts have no moving parts. They're designed to make pivoting or hinge movements in applications that don't need to compensate for misalignment.
