Lock washers

The original lock washers were developed as reliable and economical screw locking devices that fulfill the basic principle of the disc spring for a force-fitting connection and also supplement it with positive locking. Original lock washers are used wherever loosening of a screw connection due to vibration must be avoided.

LOCK WASHERS / SAFTEY WASHERS

Lock washers “S”

Our original lock washer type “S” is suitable as a screw lock for normal screw connections. They are available in dimensions M 1.6 to M 36.

Of course, special dimensions and special materials are also possible if required. The Schnorr lock washers are available as catalog items, usually immediately available, in stainless steel, galvanized, blackened and with a zinc lamellar coating.

Advantages of the original lock washers S and VS

High vibration resistance thanks to positive locking of the helical teeth on both sides

No bending moments due to the concentric application of force

No chip formation due to sliding surfaces on the teeth

Extremely high safety potential against loss of preload force and loosening of the screw connection.

No bursting effect when putting on. The prerequisite is a correct transition radius between the shaft and head
Lock washers “VS”

Our original lock washer type “VS” is always used when high-strength screw connections do not allow the lock washers type “S”. The “VS” lock washers can be used for strength classes of up to 10.9.

They have a higher material thickness and therefore achieve higher preload forces than the standard lock washer type “S”. It is available in sizes M 5 to M 30. The same applies here: special parts and requirements can be implemented if necessary.
Use lock washers correctly

To ensure the correct function and security of the screw connection, it is important that you use our lock washer correctly. Accordingly, care must be taken to ensure that the lock washer is placed directly between the screw head and the base body. No additional washer may be used.

If it is a through hole and the screw is to be fixed with a nut, for example, two lock washers should be used. One between the screw head and the base body, the other between the nut and the base body.

When assembling, care must be taken to ensure that the panes are not placed twice (on top of each other). In contrast to some competitors, our lock washer achieves its function in a single layer. Furthermore, the panes must always be mounted with the curvature facing upwards (away from the base body).
