K2 Flange Nut M10 Serrated: The Secure Fixing for Demanding PV Mounts

When installing solar panel systems that demand strong and stable mechanical connections, the K2 M10 Serrated Flange Nut offers a reliable fastening solution engineered for performance under pressure. Ideal for load-bearing joints and structures that experience high wind loads or long spans, this nut is built to stay tight.

Superior Grip with Serrated Flange Technology

The integrated serrations on the flange create a locking action when tightened against a mounting surface. This helps to prevent loosening caused by wind vibration, thermal expansion, or movement in the frame. It’s especially useful in industrial solar arrays or coastal installations where structural movement is common.

Excellent torque transfer and anti-rotation
No washer required thanks to flange base design
Compatible with M10 K2 rail systems and bolts

Built to Withstand the Elements
