Serrated lock washers increase the friction between the bolt head/nut and the mating surface. They do this by gripping into the mating surfaces. Serrated lock washers are installed between the bolt head/nut and the mating surface.

Our Conical Springs washers are manufactured as per DIN 6796 and DIN 2093. Conical Springs Washer are available as per customers requirements also. Conical Spring Washer is also called as a Disc springs / Belleville Washer, designed and developed especially for heavy bolted sections like Transformers, Rectifiers, Transmission, and many more. These Conical spring washers are made for the better effect of bolt nut setting assemblies.

The wedge lock washer purpose is to successfully secure a beveled wedge washer to a bolted joint, especially when the bolt is prone to loosening due to extreme vibrations or movement. Wedge lock washers have been meticulously tested to ensure that they can perform to their designed capabilities without loosening or breaking. Lock wedge washers utilise tension instead of friction to secure bolted joints exposed to severe vibration and dynamic loads.

Disc Springs are conically formed angular discs that are loaded in the axial direction. They can be statically loaded as well as subject to continuous dynamic loads. They can be used as a single disc or multiple in a stack combination to achieve desired deflections and characteristics. A spring stack can consist of either single spring or parallel spring sets. Disc Springs offer a well-developed solution to many engineering problems through a unique combination of high force in a small space. Disc spring stacks may be designed for extremely high loads where coil springs are not feasible at all. Disc springs Din 2093 is manufactured in high-quality spring steel grade 50CrV4 / 51CrV4, stainless steel 301, Stainless steel grade 304, stainless steel 316, Precipitation hardened 17-7, Inconel 750 and Inconel 718. Sizes ranging from outer diameter 6 mm to 350 mm and thickness of 0.4 mm to 16 mm.

Our Belleville washers are manufactured as per DIN 6796 and are available as per customersâ?? requirements. Being one of the premier Belleville washers Din 6796 supplier, stockist and exporter, we offer these quality products at best market rate to our valuable customers. Belleville Washer is also called as a Conical Washer / Conical Springs Washer, designed and developed especially for heavy bolted sections like Transformers, Rectifiers, Transmission, and many more. These Belleville washers are made for the better effect of bolt nut setting assemblies. Belleville washers primarily consists of convex disc which is supported by force at an outer periphery and another opposing force at the centre. To achieve a desired load, these washers are used as a single or in stacks. In the position of compression, our Belleville washer can generate maximum force in short spring length. It allows vibration and used to maintain a safe distance between important machine parts. Belleville washers can be used for locking purposes in the application of low dynamic load. They are used as springs or to apply pre load to bolt joint. They are used in formula one car because their ability of extreme detailed tuning. Belleville washers are also useful indicator of shrinkages made in wooden propellers of experimental aircrafts, when it is used on mounting bolts and can be detected easily. GENERAL APPLICATIONS of BELLEVILLE WASHERS ARE: - Bus Bars in Transformers Automobile & Heavy construction Agriculture & Heavy Machineries Mining & Turbine construction
