R-N SERIES RIVET NUT PROFILE
The R-N Series Rivet Nut features a heavy-duty head profile and increased wall thickness in the collapse area. This makes the R-N Series ideal for leg leveling applications as shown on page 7.
The R-N Series Rivet Nut can be installed using pneumatic/hydraulic tools or the specific rivet nut tools. The R-N Series Rivet Nut's heavier wall thickness and resulting upset load require this type of tool to be used for installation.
The R-N Series can be installed either before or after the finish.

The R-N Series Rivet Nuts are manufactured using state-of-the-art cold-forming technology. This provides very precise tolerances. All surfaces of the R-N Series are FORMED, not machined. This provides excellent quality.
The internal thread of the R-N Series Rivet Nut is rolled not machined. This provides excellent thread strength.
INCREASED PUSH-OUT LOADS are achievable in leg leveling applications when using the R-N Series due to their heavy-duty head profile and thick wall construction.
- SUPERIOR THREAD STRENGTH is provided due to our internal rolled thread manufacturing process.
- SUPERIOR CORROSION RESISTANCE is provided by our standard cadmium finish (72 hours. salt spray)
UNIFORM INSTALLATION is guaranteed because of the dimensional tolerances and concentricity tolerances built into our product made possible by our cold-forming technology.
- AVAILABLE in steel and aluminum.
OPEN-END DESIGN TYPES
Open-end design is not closed off and threads are a visible, economical solution when parts are frequently changed out or don't have exposure to corrosion

CLOSED-END DESIGN TYPES
The thread area is enclosed eliminating leakage past the threads from either side of the application.
KEYED HEAD DESIGN TYPES
An underside of the head "key" projection when placed into a matching "keyed" hole design provides additional torque resistance.
100° COUNTERSUNK HEAD DESIGN TYPES
A 100° countersunk head profile when installed into a matching countersunk hole provides a flush installation.
