SAFETY WASHER S5- SS

The original SCHNORR® Safety Washers were developed as a reliable and economic bolt locking device with the basic principle of a disc spring. This ingenious form combines the advantage of security through friction and mechanical locking.

SCHNORR® Safety Washers are in the form of a disc spring but with a trapezoidal cross-section and serrations on both sides. The outer diameter is matched to the head diameter of pan head and socket head cap screws.

The standard safety Washer type "S" is available for screws of sizes M1.6 to M36 and of property classes up to 8.8. For screws of property classes 8.8 and 10.9, higher pretension forces might be required.
