Product overview
Rivet nuts are permanent mechanical fasteners installed from one side. They form a high-strength internal thread in thin metal sheet, profiles, composites and plastic panels without access to the rear face, which makes them ideal for blind-hole installation. Assembly is fast and the joint is firm and vibration resistant, so they are widely used in automotive, new energy, appliance and sheet-metal equipment assembly. Available in carbon steel and 304/316 stainless steel, including a corrosion-resistant stainless series developed for new energy vehicles.
Key assembly advantages
1. One-side blind installation, ideal where there is no access behind the panel
2. Combines riveting and a female thread in one part, replacing weld nuts and clinch nuts
3. Each nut installs in about 3 seconds, giving very high efficiency on automated lines
4. Knurled anti-slip teeth on the body prevent rotation and slipping; every size can be supplied with anti-corrosion and anti-loosening finishes

Industry challenge — the 15–85 rule and the project cost influence model
In today's fast-moving market the core challenge for R&D is this: the early decision window is extremely short, yet it fixes most of the lifecycle cost; later corrections, however heavily funded, remain extremely expensive, so risk and reward are badly mismatched.
Another core pain point: companies over-focus on visible purchasing cost (only 15% of total cost) and long overlook the 85% of hidden cost. Without systematic coordination across product design, supply-chain control and after-sales service, an early mistake in fastener selection keeps triggering high manufacturing cost, batch rework, quality complaints and warranty claims, sharply raising the total lifecycle cost of the finished product.
