    Original SCHNORR®

    Safety Washers

    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. 
    Original SCHNORR® safety washers are now used world wide where secure fastening connections to counter the effect of vibration are required.

     

    Functional Principle

    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 the pan head and socket head cap screws.   

    SCHNORR® safety washers are available in two versions: the standard safety washer type “S” is available for screws of sizes M1.6 to M36 and of the property classes up to 8.8. For screws of property classes 8.8 and 10.9, higher pretension forces might be necessary. These are covered by our reinforced washers type “VS”.  

    Due to the conical form, optimal traction is achieved at highest positive locking due to the helical gearing.

    Functionality and the correct use

    of the original SCHNORR safety washers are briefly explained within the following video

    safety washers Type „S“

    The original SCHNORR® safety washers “S” are suitable for general requirements and are available for bolt sizes from M 1.6 to M 36 in strength grades up to 8.8.






    safety washers Type „VS“

    The original SCHNORR® safety washer type “VS” can be used with high-strength bolts of grade 8.8 to 10.9 without any restrictions. This extra strong safety washer has increased thickness to accommodate higher pre-tensioning loads. The outside and inside diameters as well as the serrations are the same as type “S.” It is available for screws from M5 to M30.

    Serrated safety washer “UV”, fixed with bolt/screw

    For screws with fixed safety washer

    These safety washers are dimensioned so that they can be mounted with bolts or screws from M2.5 to M10. Installation takes place before thread rolling, so the safety washer sits securely on the shaft.
