Washers are generally used to guard components from the load of threaded bolts. When driving a bolt into an element, you’ll expose the half to mechanical stress. The top of the bolt will press in opposition to the higher floor of the half, leading to stress. Relying on how a lot stress the half is uncovered to, the half might crack or in any other case maintain injury.
Washers are designed to guard components from injury similar to this by distributing the bolt’s load throughout a bigger floor space. The load of the bolt will unfold throughout the washer. Whereas most washers are steel, nonetheless, some are non-metallic. To be taught extra about non-metallic washers and the way they work, preserve studying.
Overview of Non-Metallic Washers
Non-metallic washers are characterised by their use of a non-metallic materials. You could find washers fabricated from a wide range of supplies. A few of them are fabricated from steel, similar to stainless-steel, aluminum or brass. Non-metallic washers are fabricated from an artificial materials.
Frequent supplies used within the development of non-metallic washers embody the next:
- Nylon
- Rubber
- Plastic
- Fiberglass
Purposes for Non-Metallic Washers
What are non-metallic washers used for precisely? They’re typically used to distribute the load of a bolt — similar to steel washers. They will shield components from stress-induced injury by distributing the bolt’s load throughout a bigger floor space.
When fabricated from a non-metallic materials, washers can present electrical insulation. All metals can conduct electrical energy. This is because of the truth that free electrons transfer round in steel, which permits electrical energy to stream by steel with minimal resistance. Some metals are extra conductive than others, however they’ll all conduct electrical energy. Non-metallic supplies, although, provide electrical insulation.
Non-metallic washers designed to be used in purposes are often called insulating washers. They’re generally utilized in electrical gadgets and tools. Due to their use of a non-metallic materials, they gained’t conduct electrical energy.
Non-metallic washers are sometimes used as seals as effectively. Relying on the precise kind of non-metallic materials from which a washer is made, it might exhibit elastomeric properties. The washer might compress underneath the load of a bolt, thus making a water- and air-tight seal.
Medical gadgets typically comprise non-metallic washers. Steel washers are reactive and, due to this fact, can corrode and degrade over time. Non-metallic washers, alternatively, are non-reactive. They provide higher resistance to chemical substances, and so they provide higher biocompatibility than their steel counterparts.
