| SCHNORR™ Safety Washer HDS-30 (Code: 701 800) |
| Product Technical Details |
| The Schnorr™ HDS-30 (SP 30) is an original safety washer specifically engineered to provide superior protection against axial loading and heavy vibration in high-strength M30 bolt connections. Operating on the proven Schnorr™ disc spring principle, these washers eliminate loosening by maintaining the preload force of the fastener. It is a world-class solution for secure assembly in heavy industry, mining, and large-scale infrastructure projects. |
| Why Choose Schnorr™ HDS Series? |
| • Maximum Loosening Protection: Ensures peak safety for M30 connections under extreme vibrational and dynamic loads. • Superior Spring Force: Keeps preload stable despite thermal expansion or surface settling. • Compact Engineering: Designed to match standard bolt head dimensions, providing high contact force in limited spaces. • German Quality Standards: Maintains technical integrity and elasticity even in the harshest environments. • Secure Grip: Ensures a balanced and stable connection without damaging the host surface. |
| Applications |
| • Power plants, wind turbine towers, and heavy structural steel assembly. • Mining machinery, stone crushing plants, and massive hydraulic presses. • Heavy-duty cranes, port equipment, and bridge construction. • High-vibration large-scale industrial motors and gearbox mounting points. |
