Screw Washer Assemblies
Washers
Plain Washers are also known as Flat washers and their work is to distribute the fastener's load while reducing heat and friction during the tightening process. They can also be used as spacers, as is common in industrial and domestic applications. Plain washers do not have a locking function, rather they are used to protect the mating surface from damage. Plain washers can also be used when the hole is bigger than the nut. The main role of flat washers is to increase the size of a screw's bearing surface area and reduce the surface pressure applied on the fastened object. The most common type of washers is plain washers, also known as flat washers. Looseness can result when the bearing surface sinks under the surface pressure, so using a flat washer to reduce the surface pressure is very effective.
The conical washer also known as Belleville washer, holds tight where heat or vibration might shake standard washers loose. The conical washer has a cone shape that compresses against the underside of the bolt head and into the furnishing material. Conical washers can be reused, repeatedly, as long as they are not damaged. They are commonly used to bear remarkable high loads in small areas. These washers are very frequently used in different industries because they can absorb and dampen shocks and vibration as well. There are several advantages of using this washer likes - Vibration Control Pre-Load Increased Load Increased Deflection Spacing Dampen/Absorb Shocks
Machine washers
Serrated lock washers increase the friction between the bolt head/nut and the mating surface. They do this by gripping into the mating surfaces. Please note that these washers come in two different types - internal toothed and external toothed. Serrated lock washers are installed between the bolt head/nut and the mating surface. And when it comes to loosening resistance, the externally toothed washer does a better job than an internally toothed washer. But the internally toothed washer comes with greater locking abilities. It can also allow the washers to withstand extremely high stress and force. In both internal and External types, the teeth bite into the joint material and create a holding pressure that doesn't loosen even during continuous vibrations. In most cases, a combination of both the fasteners is used to secure smaller objects in place. In HELLARY it is available in different materials stainless steel, carbon steel, and alloy steel.
A serrated washer is also known as Vibration Proof Washers. Serrated lock washers increase the friction between the bolt head/nut and the mating surface.They are available in various sizes to fit bolts or screws.Serrated Washers are fitted internally to the equipment before a lock nut and act as an anti-vibration device to prevent the Cable Gland or accessory from inadvertently loosening in service.Often used on cable gland entry threads, these washers come in stainless steel as standard but can be made in a number of materials upon Customer request.
Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations. This type of washer can be used, that supposed prevent losing and spring action and edge that digs into the screw-on the reverse. Locking washers, which prevent fastening or loosening by preventing unscrewing rotation of the fastening device.A spring washer assembly is placed under the nut to prevent the loosening of the nut.
Square Taper washers are known as square or half-round, Taper washers are designed to be used on channel sections, underneath nuts with tapered flanges to enable the bolt assembly to fit square when tightened. At HELLARY it is available in different materials like stainless steel, Alloy, Non-ferrous, etc.
Square Washers are also known as construction square plate washers. Square Washers are typically thin pieces of material with a hole in the middle that is used to distribute the load of a threaded fastener, such as a screw or nut.
Star washers are a specific type of washer designed to increase the locking force as well as torsional resistance by resisting torque applied by the nut, preventing it from unscrewing or separating. At HALLERY these washers are available in stainless steel, plain, or zinc plated finishes.
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
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.
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.
