I like to spend time on YouTube learning different skills and how to make home appliances and tools. It is much easier than you think if you have the right equipment and motivation for the job. I have enjoyed gardening and mowing my lawn to get a perfect finish. I have also learnt a few tips to maintain my car. Lumber application has been a bit more challenging because my blots keep losing grip after some time of use. After searching online for a while, I discovered that I was missing out on a key element.

Split lock washer vs spring lock washer – A Detailed Comparison

Material and durability

Hilitchi Stainless Steel Spring Wave Washer is made of high quality stainless steel. This makes the spring washer suitable for almost any type of weather. Since they are corrosion resistant, you can probably re-use them several times.

The split lock washers are made with a zinc finish which provides a moderate resistance to corrosion. This makes it durable to some extent. The strong stainless steel on the inside makes the material strong and long lasting.

Design

Hilitchi Stainless Steel Spring Wave Washer is kind of like the Belleville design wise. The only difference is that the Hilitchi spring washer is curved in one direction. When installed, there are few contacts points between the screw head or the nut and the washer. The wave is meant to provide some kind of spring pressure when it is compressed. You can use it as a lock washer but it doesn’t mean it can be as effective.

A ring split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener’s head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.

Installation

The Hilitchi spring wave washer is perfect for electronic connections in the house hold. It can be used with several other applications as well. They are popular in marine and automotive construction and commercial appliances. This spring lock washer is a left hand helix which means you have to turn it in a clockwise direction to tighten it on a bolt. Turning it in the opposite direction will raise the edges making it hard to turn.

There have been questions and debates over the use and effectiveness of the split lock washers. According to some users, the split lock washers cannot be installed too tightly. This is because they become flat against the substrate leading to zero resistance to rotation.

split vs spring lock washer

The split lock washer is shaped just like a regular washer but has a noticeable split at one point. It offers you a circular bearing that had split ends that function by biting into the material that is being installed. The shape of this split washer carries a benefit of its own. When there is too much compression near the bolt, this washer will twist until it flattens. In return, this reduces spring rate of the bolt and keeps the force on the same level. In short, it provides an effective way to prevent bolts from loosening.

The shape also provides you with a locking feature and helps to keep it nice and tight. Basically, it is rounded and has a split at one point of the circumference.  The split is responsible for the force caused by the washer between the substrate and fasteners’ head.

This split washer, like most, has a left hand helix. This property will only allow you to tighten the washer strictly in the clockwise direction.  If you try to tighten it in the ant-clockwise direction, it will resist turning due to the bolting of the underside part of the washer.

Pros

  • It has a zinc finish to moderate any corrosion resistant
  • You can use it with bolts and nuts that have a similar diameter
  • You get 100 pieces in the package

Cons

  • It is somewhat useless for locking
