The strongest and most corrosion-resistant stainless steel key-locking inserts we offer. Made of A286 stainless steel, these inserts stand up to salt water, harsh chemicals, and even high temperatures. Since you drive the keys into the surrounding material, these inserts also give you a more secure hold than thread-locking inserts. Use them to repair or add new, reusable threads to aluminum and other soft metal. They’re comparable to Keensert® inserts. Those that meet stringent military specifications or National Aerospace Standards have high-precision threads and tight tolerances.

Install them using 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 large holes. They’re often used when you need to drill out damaged threads.

The strongest and hardest press-fit nuts we offer. In addition to their sturdiness, these A286 stainless steel nuts withstand harsh chemicals. They add permanent threads to sheet metal, like weld nuts but without the setup and mess. Unlike most press-fit nuts, they’re even hard enough to install in stainless steel panels. Also known as clinch-style captive nuts, press them into a drilled or punched hole with an arbor press or similar pressure tool. The pressure forms your sheet metal into the knurls of the nut, making the nut inseparable from the sheet. Installation requires access to both sides of the panel.
