Introduction to SCHNORR stainless steel safety washers：

SCHNORR safety washers can be made from different materials and are available with various surface finishes.

Original SCHNORRStainless steel safety washerswere developed as a reliable and cost-effective bolt locking device, based on the principle of a disc spring. This ingen-ious design combines the safety advantages of friction and mechanical locking. Original SCHNORR safety washers are now used worldwide wherever securefastening connections are required to resist vibration, thermal expansion, and other influences.Applications span automotive, mechanical, plant engineering, conveyors, electrical, and many other industries. Wherever reliable fastener securing is required.  

Stainless steel safety washersFor example, in lawn mowers, textile machinery, machine tools, and many other applications.

Original SCHNORRStainless steel safety washersDesigned in a disc spring shape, but with trapezoidal cross-sections and serrations on both sides. The outer diameter matches the head diameters of pan-head and hex socket screws.head diameters.

SCHNORRStainless steel safety washersClassification:

SCHNORR safety washers are available in two versions. The standard safety washer "S" is suitable for screw sizes from M1.6 to M36 and property classes up to 8.8. For screws with property classes 8.8 and 10.9, higher preload forces may be required. These are covered by our reinforced washer "VS".

Due to the conical shape and helical gear action, optimal traction force is achieved at high positive locking.
