Part Number: SSW-S10
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 and bolts. The outer diameter of the washer is matched to the head diameter of pan-head and hexagon socket head cap screws or bolts. As a result, these safety washers can be used with almost any type of screw or bolt, including those with recessed heads (any with parallel faces, not countersunk screws/bolts). The ingenious form of the Schnorr safety washer offers the combined security advantages of friction and mechanical locking. Supplied as a pack of 10 washers.
