Serrated Washers are disc springs with trapezoidal cross section on both sides for gripping. IIS serrated safety washers are ready to fit washers to sustain preload and avoid loosening. The advantages of Serrated Safety Washers are: Used for high vibration resistance due to positive rib contact Excellent pretensioning Through proper radius selection, no splitting, cracking occurs during tightening The concentric force of the washer eliminates the chances of bending the fastener Extensive application and flexibility, minimizes stocks

IIS makes all types of wave Spring washers as per DIN 137 and DIN 6904. IIS Wave washers are made from prime quality spring steel, stainless steel, copper and other material which are readily available in very standard sizes. Wave washers are wavy metal washers designed to offer a compensating spring force and maintain a load or take up shock. These are the disc of irregular shape formed in such a way that when loaded it deflects acts like a spring and provides a preload between two surfaces. Wave washers are very useful for limited radial space and moderate thrust load e.g Axial loading of B

Serrated Washers are Disc Springs with Trapezoidal Cross Section on both sides for gripping. IIS serrated safety washers are ready to fit washers to sustain preload and avoid loosening. As the bolt is tightened the serrations crunch into the mating faces and prevents the screw from loosening up due to vibration. Also, the disc shape holds the necessary tension. They are available in various sizes
