Item # RNNM08C2AP
M8 FLANGE KNURLED BODY RIVETNUT, 3.80-7.90mm GRIP, ALUMINUM, PLAIN
- UM: EA
- Brand: RIVETKING
The RNNM08C2AP is a M8 aluminum, plain flange-style knurled body rivet nut from the RivetKing IKF (low profile head) thinwall series. Designed for blind installation in sheet metal and panel applications where threads are needed but back-side access is impractical, this rivet nut installs from one side of the workpiece and provides a permanent threaded socket once set.
Typical applications: Heavy use in automotive accessories, off-road vehicle modifications, equipment manufacturing, panel mounting, and general industrial fabrication where moderate load capacity is needed. The aluminum, plain material is well-suited to lightweight applications, automotive aftermarket, aerospace, off-road, marine fittings, electronics enclosures.

| Part # | Grip | Material | Use When |
|---|---|---|---|
| RNNM08C1AP | 0.70-3.80mm | Aluminum | Shorter grip (same material) |
| RNNM08C2AP ← current | 3.80-7.90mm | Aluminum | Panel 3.80-7.90mm |
| RNNM08C2SS | 3.80-7.90mm | 18-8 SS | Marine / food / outdoor |
| RNNM08C2SY | 3.80-7.90mm | Steel YZ | General industrial / cost |
Installation: Drill a 13.5mm hole in the workpiece. Insert the RNNM08C2AP from the accessible side and set with a rivet nut tool — the body collapses against the back side of the panel and the knurled flange grips the front side to prevent rotation under torque. Recommended grip range is 3.80-7.90mm (sheet thickness).
For step-by-step instructions: see our How to Install Rivet Nuts guide for the complete process, common mistakes, and verification tips.
Tool selection: Use a pneumatic or hydraulic rivet nut tool for production volume. A battery-powered cordless tool also works well at this size. Hand tools are workable for occasional installs but become fatiguing in volume. Both spin-spin and spin-pull tool types are compatible with the IKF series.
Drill bit needed: 13.5 mm (17/32"). We stock the matching Triumph bit — TRI94134 — ships same day with your rivet nuts. Full drill bit chart.

Rivet Nut vs. Other Threaded Inserts
| Type | Best For | Limitations |
|---|---|---|
| Rivet Nut (this part) | Permanent threads in sheet metal, blind installation, one-side access | One-shot install; needs proper drill size and deburr |
| Plus Nut / Jack Nut | Soft or brittle panels (plastic, fiberglass, drywall) | Lower torque ratings than rivet nuts; not for steel panels |
| Well Nut | Vibration damping, waterproofing in thin panels | Rubber body limits load capacity and temperature range |
| PEM (self-clinching) | High-volume sheet metal production at the press | Requires press tooling; not a blind/field install |
