Item # RNNM12C2SY
M12 FLANGE KNURLED BODY RIVETNUT, 5.10-8.90mm GRIP, STEEL, YELLOW ZINC PLATED
- UM: EA
- Brand: RIVETKING
The RNNM12C2SY is a M12 steel, yellow zinc plated 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: Used in heavy equipment, frame and chassis applications, structural attachments, equipment skirting, and any application requiring high pull-out strength and torque resistance. The steel, yellow zinc plated material is well-suited to general industrial, automotive, equipment manufacturing, structural, sheet metal fabrication.

Installation: Drill a 17.47mm hole in the workpiece. Insert the RNNM12C2SY 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 5.10-8.90mm (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: Pneumatic, hydraulic, or pneudraulic rivet nut tools are recommended for this size — manual tools are not practical due to the force required to set the larger threaded body. Both spin-spin and spin-pull tool types are compatible with the IKF series.
