M5-M10 DIN Thin Carbon Steel/stainless steel Square Nut

High Strength M5-M10 DIN Thin Carbon Steel/Stainless Steel Square Nuts | Corrosion-resistant & Precise Fit

M5-M10 DIN Standard Thin Square Nuts are designed for space-constrained industrial applications. They are made of high-quality carbon steel (galvanized) or 304/316 stainless steel, providing excellent rust and corrosion resistance. They meet DIN 557 standards to ensure precise fit with various bolts and clamps, and are suitable for harsh environments such as machinery manufacturing, automobile assembly, and building structures.

Core Advantages:

Ultra-thin design – 20% thinner than conventional nuts, suitable for small installation spaces.
High tensile strength – carbon steel models reach grade 8.8, and stainless steel models reach A2-70/A4-80 standards.
Anti-loosening – the square structure increases the contact surface and reduces the risk of loosening caused by vibration.
Multiple material options – carbon steel (economical and durable) or stainless steel (highly corrosion-resistant).

Industry Uses:
Mechanical Equipment – ​​Suitable for motors, pumps and valves and other parts that require tight fastening.
Automotive Industry – Chassis, high vibration areas around the engine.
Building Curtain Wall – Stainless steel models are highly weather-resistant and suitable for outdoor steel structures.
Electronic Appliances – Thin design saves PCB board installation space.

FAQ
