Industrial Grade M3-M12 Stainless Steel Rivet Nuts & Threaded Inserts
Our M3 to M12 series rivet nuts represent the pinnacle of fastening technology for thin-walled materials. These high-precision threaded inserts are engineered to provide heavy-duty, permanent internal threads in applications where backside access is limited. Whether you require standard M6 rivet nuts for automotive use or M10 heavy-duty inserts for construction, our products meet ISO 9001 quality standards.
Why Choose Our M3-M12 Rivet Nut Series?
In the world of industrial fasteners, precision is measured in millimeters. Our range of rivet nuts (from the small M3 to the robust M12) offers several distinct advantages:
- High-Grade Material: Available in 304 Stainless Steel (for general corrosion resistance) and 316 Stainless Steel (for marine-grade environments).
- Versatile Body Styles: We offer Knurled Body rivet nuts for increased spin-out resistance and Hexagonal Body for the highest torque requirements.
- Standardized Sizing: Fully compliant with DIN 7338 and UNC/UNF threading standards.
- Blind Installation: Perfect for 0.5mm to 6.0mm grip ranges where only one side of the workpiece is accessible.

Applications of Metric Rivet Nuts in Modern Engineering
From M4 inserts in electronic enclosures to M8 fasteners in automotive frames, our products serve a wide array of industries:
- Automotive Industry: Used in M6 and M8 sizes for attaching roof racks, spoilers, and internal trim where the sheet metal is too thin for tapping.
- Green Energy (Solar/Wind): M10 and M12 stainless steel rivet nuts are essential for securing solar panel brackets in outdoor environments.
- Aerospace & Marine: 316 Stainless Steel M5 inserts provide the necessary salt-spray resistance for marine cabinetry.
- Furniture Manufacturing: M6 threaded inserts are widely used in metal-frame office furniture for easy assembly and disassembly.
Professional Installation Guide for M-Series Rivet Nuts
To ensure maximum pull-out strength and torque-to-turn performance, follow these professional tips:
1. Correct Hole Sizing: Always use a high-quality drill bit. For an M6 rivet nut, a 9.0mm hole is critical. A hole that is too large will lead to “spinning” during installation.
2. Tool Calibration: Adjust your pneumatic or manual rivet nut tool stroke according to the material thickness. Over-setting can damage the M3 or M4 internal threads.
3. Material Compatibility: Ensure the rivet nut material matches or exceeds the corrosion resistance of the host material to prevent galvanic corrosion.
Frequently Asked Questions about Rivet Nuts
Q: Can I use an M6 rivet nut in a 10mm hole?
A: No. An M6 rivet nut requires a 9.0mm hole. Using a 10mm hole will result in a loose fit and potential fastener failure.
Q: What is the difference between 304 and 316 M8 rivet nuts?
A: 304 is standard stainless steel for most indoor/outdoor uses. 316 contains molybdenum, making it superior for marine and chemical exposure.
