18-8 Stainless Steel Easy-to-Install Thread-Locking Inserts
Made of 18-8 stainless steel, these inserts have good corrosion resistance. Also known as E-Z Lok, they use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours. They may be mildly magnetic. Installation requires a drill bit and a standard tap. Then set the insert with an installation bit, a slotted screwdriver, or a bolt with two nuts.
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.

Black-Phosphate Steel Easy-to-Install Thread-Locking Inserts
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.
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.
To drive slotted inserts, you can use a slotted screwdriver instead of using an installation bit or a bolt and two nuts.

316 Stainless Steel Easy-to-Install Thread-Locking Inserts
These inserts are the most corrosion-resistant thread-locking inserts we offer. Also known as E-Z Lok, they use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours. All have thick walls for strength and can be used to fill a large hole with stripped threads. They may be mildly magnetic. Installation requires a drill bit and a standard tap. Then set the insert with an installation bit, a slotted screwdriver, or a bolt with two nuts.

Easy-to-Install Thread-Locking Insert Assortments
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.

For fast installation, use these installation bits with power drills and drill presses.
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.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

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 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.
