Spring washers are locking washers that are used when there is a need to prevent a fastener from loosening up as a result of vibration. They are also frequently called split lock or split ring washers. A spring washer has a split in the washer area that when tightened each side of the split bites into the nut and the installing surface.

There are two kinds of spring washer, square and rectangular area. This refers to the shape of the split end area. A simple method to discriminate is that when viewed from above, rectangular section spring washers look flatter than the square section variations, which look a lot more rounded.

As the washer is tightened up under load, the vertical cut ends of the washer grab the nut and bind against it. When the nut is completely tightened up, the split in the washer must still be somewhat out of positioning. This is visual evidence that the spring washer is still running as planned and in fact applying a force on the fastener, as revealed in the image listed below; If the nut is overtightened the impact of the spring washer is considerably minimized, as the split ends of the washer are then brought into alignment as the washer is flattened, reducing or entirely eliminating any stress on the fastener.

If an extra washer is required to spread the load (as in our image above) it need to be utilized in between the spring washer and the installing surface, i. e. the spring washer ought to be placed next to the nut. Exist any alternatives to spring washers? This really much depends on the application.
