M5 Hex Flange Lock Nut – DIN 6927 (Class 8, Bright Zinc Plated)

Hex Flange Lock Nuts – DIN 6927 (Class 8, Bright Zinc Plated)

These all-metal lock nuts combine a standard hex nut with an integrated flange. The built-in washer distributes load evenly and resists loosening on uneven or vibrating surfaces. Made from Class 8 steel for moderate to heavy-duty applications, they offer reliable strength and durability. The bright zinc (Cr+3) coating provides enhanced corrosion resistance and is RoHS-compliant. A deformed thread section creates prevailing torque, giving the nut a self-locking function that remains effective over multiple installations.

Key Features

• Integrated flange: Built-in washer spreads the clamping force and reduces the need for separate washers.
• Self-locking all-metal design: Deformed thread area provides prevailing torque for vibration-resistant fastening and prevents loosening.
• Grade 8 strength: Manufactured from Class 8 steel for dependable performance in machinery, automotive and construction applications.
• Bright zinc plating: Cr+3 zinc finish offers corrosion protection and a clean appearance while complying with RoHS requirements.
• DIN 6927 / EN 1664 compliant: Ensures precise fit and performance across metric coarse thread sizes (typically M5–M16).

These flange lock nuts are ideal where vibration resistance, load distribution and reliable clamping are essential, such as in automotive assemblies, machinery and structural connections.
