Add threads to sheet metal and panels in confined spaces with limited backside clearance. At installation, these compact nuts collapse into themselves and press slightly outward, creating snug-fitting threads half the length of a standard nut but just as strong. With a thin top flange that creates a near-flush fit, they're ideal for light duty fastening in small enclosures or housings.

Install these nuts using a hand- or power-driven rivet nut tool. In thick material, drill or punch a slightly larger hole to ensure the nut body expands uniformly.

Repair damaged threads or create new ones. These convenient assortments include helical inserts, an installation tool for each thread size, a drill bit, and a tap. The inserts are also known as Heli-Coil inserts.

Quickly restore stripped threads—these inserts come with through-hole taps and installation tools. The tough coils on these inserts expand once installed to anchor in a tapped hole.

The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration. Use these inserts to create or repair threads in pumps and other machinery that shakes and rattles. Also known as Heli-Coil inserts.

Installation requires a drill bit, a helical insert tap, and an installation tool.

Restore, reinforce, or create threads in metal. The tough coils on these inserts expand once installed to anchor in a tapped hole. Also known as Heli-Coil inserts, they're often used in engine heads and machinery housings where strong connections are critical. Unlike threadlocking inserts, you can remove and reuse them without them losing their strength.
