Safety & Conical Spring Washers
These are used for locking a device and reducing the vibration. They reduce loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.
Washers are available in a wide range such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.

Contact Washers are Conical shaped Lock Washers formed with a ribbed top surface. The conical shape exerts locking force 360 degree around the underside of the screw head/ nut by generating tension.
The ribbed top surface further enhances the locking force and resists the torqued fastener connection potential for loosening under pressure and vibration.
This is a single-sided toothed and non-slip locking washer, providing the designer the ability to secure wobble-prone screw effectively. It is particularly suitable for use on slot fasteners, dynamic cross-loaded to the screw connections and applications that require high biasing forces.
These washers are widely used in locomotives, appliances, elevators, electrical towers, medical machinery and electronic equipment.
