| SCHNORR™ Safety Washer HS-10 (Code: 431 530) - Zinc+Passivated |
| Product Technical Information |
| Schnorr™ HS-10 (431 530) is an original safety washer with a zinc coating and a passivation process that increases corrosion resistance. It has been developed especially for M10 cylinder-head bolts (Inbus) with narrow recesses. Thanks to the original disc spring washer form, it stabilizes the preloading force of the bolt in vibration-prone environments and completely prevents mechanical loosening, maximizing connection reliability. |
| Areas of Use |
| • Connections in humid or outdoor environments where there is a corrosion risk. • Narrow mounting recesses where M10 cylinder-head (Inbus) bolts are used. • Moving industrial machines and automation lines. • Electrical panels and busbar systems. • Assembly applications in automotive and defense industries. |
| Why Schnorr™ HS Series? |
| • Corrosion Protection: Offers long service life thanks to the zinc coating. • Optimized Narrow Diameter: Perfect fit to the standard recesses of M10 Inbus bolts. • Superior Loosening Protection: Prevents torque loss in shock and vibration environments. • Continuous Spring Effect: Balances the seating effect in the bolt connection with spring force. • Original German Technology: Safety at world-standard levels for critical connections. |
