It is a loosening prevention mechanism that utilizes tension from a combination of wedge-shaped cams.
The "Nortlock Washer" is a locking device that utilizes tension from a combination of wedge-shaped cams. When the nut attempts to rotate, only the inner cam surface moves. However, because the angle of the inner cam is greater than the lead angle of the screw, it becomes difficult to overcome the cam, preventing loosening (backing off). 【Features】 - Excellent corrosion resistance: Steel: SC material with Delta Protect treatment; Stainless steel: SUS316 is used. - Easy to install and remove, and can be reused.
