These Schnorr Safety Washers are in the form of a disc spring which is serrated on both sides and of trapezoidal cross section. Their internal diameters are matched to the thread diameter of screws/bolts. The outer diameter of the washer is matched to the head diameter of pan-head and hexagon socket head cap screws/bolts. As a result, the Safety Washer can be used with practically any screw and bolt type, including those with recessed heads (cannot be used with countersunk screws/bolts). The ingenious form of the Schnorr Safety Washer combines the advantages of security through friction and mechanical locking.
Advantages:
- The shape of the cross section ensures the locking effect is at the outside diameter which ensures the greatest resistance to loosening.
- High resistance to vibration due to positive locking of the serrations.
- The closed ring form results in a high degree of pretensioning, i.e. an excellent frictional connection.
- Concentric application of force eliminates bending in the bolts.
- Sliding surfaces allow tightening without damaging the surfaces.
- No splitting during tightening with proper transitional radius between bolt shaft and bolt head.
- Suitable for captive fitting on a wide range of bolts.
The Schnorr Safety Washer is suitable for normal duty applications.
Supplied in packs of 10.
