18-8 Stainless Steel Key-Locking Inserts

1. Mil. Spec. Stainless Steel Key-Locking Inserts. These inserts are made to stringent military specifications. 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 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. Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

2. Black-Phosphate Steel Key-Locking Inserts.

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 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. Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole with stripped threads. Inserts with an extra thick wall are stronger than thick- and thin-wall inserts. Use them to reduce the size of tapped holes.

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

A bolt plug is a screw thread both inside and outside, there are four or two on the exte-real thread pin pin-specific fasteners, bolt into the tapping hole after the tapping, and then push the latch, play a strong Fast-ening effect.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. Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

Inserts with an extra-thick wall are stronger than thick- and thin-wall inserts. Use them to reduce the size of tapped holes.
