Stainless Steel Star Washers Manufacturers India - Bhalla Fasteners

A washer is a fitting used to distribute loads on threaded fasteners such as nuts or bolts. They are usually disc-shaped, sometimes square with holes. The application determines the location of the hole in the gasket. It may or may not be centered.    

 They are available in a variety of shapes, sizes and accessories. The most commonly used washers include flat or flat washers, fenders, dish washers, wedge washers and tooth washers. Serrated washers are also known as toothed lock washers or star washers.    

The presence of recesses directed radially into or out of the component. The indentations present on the washer cut into the bearing surface, so they are generally well equipped as a type of block. Especially when used in combination with a soft substrate such as aluminum or plastic. Another reason for preferring Star Lock washers over regular washers is that they resist rotation more than flat washers on hard surfaces

The rationale for this is the presence of some form of stress. The tension between the washer and the surface exists over a much smaller area, i.e. on the teeth. There are four types of star washers: internal, external, combination, and countersunk.

The recesses on the inner Star Lockwasher are located on the inner edge of the washer, which makes them more aesthetically pleasing. On the other hand, washers with recesses on the outer edge are called outer washers. They are known to provide the best sealing ability as the outer Star Lock washers have a larger circumference. The Star Lock Wash Combination has recesses on both edges for maximum holding power

The countersunk star washer is suitable for use with flat head screws. Serrated or star lock washers are well suited for ground connection.    

Where a metal fin or object is electrically connected to a surface. The teeth of a stainless steel star washer cut through surface oxide, paint or any other finish that may be present on its surface to provide an airtight conductive path.    

In such an application, the washers do not fit under the screw head. Nor their placement under the nut. However, their location is between the bonding surfaces. In such cases, the toothed washer does not provide rotation lock.    

Since star washers must withstand heavy loads, they are usually constructed using durable materials. However, this is not the only factor that determines the adequacy of an application. Other factors include the type of environment, such as the presence of highly corrosive environments such as acids or chlorides, or the temperature setting per degree altitude, or cryogenic and tensile properties. Typically materials such as duplex, super duplex stainless steel, hastelloy, inconel, nickel, stainless steel, etc. If cost is your top priority, a carbon steel washer with a special surface treatment might be an alternative.
