| Product Technical Information |
| The Schnorr™ HDS-20 (SP 20) is an original safety washer designed to provide superior protection against axial loading and heavy vibration in high-strength M20 bolt connections. Operating on the 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, automotive, and energy sectors. |
| Why Schnorr™ HDS Series? |
| • Anti-Loosening Protection: Provides maximum safety for connections under vibrational and dynamic loads. • High Spring Force: Keeps the preload stable despite thermal expansion or surface settling. • Compact Design: Saves space with an outer diameter structure suitable for standard bolt head sizes. • Extreme Durability: Maintains spring characteristics even in harsh environments according to TDS data. • Secure Assembly: Ensures a stable grip without damaging the bolt surface. |
| Applications |
| • Assembly of heavy machinery and large-scale industrial equipment. • Automotive drivetrains, chassis, and suspension systems. • Wind turbines and structural steel constructions. • High-vibration pump, compressor, and generator connections. |
