There are various kinds of equipment that contains bolted joints. The range of respective applications is wide and includes transportation, manufacturing, power generation, and more. In these joints, lock nuts provide a clamping force to hold the components of the joint and, correspondingly, the parts of equipment together. However, there are various factors that can weaken this clamping force. They include an under-tightened bolt, equipment vibrations, embedding of the nut into the joint surface on a micro level, and mechanical shocks caused by varying loads from certain kinds of machinery.
The resulting loosening is not just an unpleasant occurrence. It may lead to multiple malfunctions such as the leaks of gas or fluid, bolt’s breakage, or other kinds of damage which can harm the equipment and even lead to accidents. Therefore, you should make sure that your machine and its components are in perfect working order, and even such small parts as lock nuts are of proper quality. You can obtain reliable lock nuts in our store. Our range covers a variety of purposes; you can select spin lock nuts, mechanical lock nuts, and nylon inserts. Made from exceptionally durable materials, our products feature superior corrosion resistance, practicality, and overall quality.
