Heavy Hex Bolt Factory Introduces Why Screws Should Use Spacers

Jun 16,2021 / Industry News, News / Author: ShengKui

Heavy Hex Bolt Factory introduces why the screws use spacers:

1. In the screw with nut, the function of the gasket is to increase the contact area, reduce the pressure, and protect the parts and screws.

2. Gasket refers to a material made of paper, rubber sheet, or copper sheet and placed between two planes to strengthen the seal. The sealing element is set between the static sealing surfaces in order to prevent fluid leakage.

3. Gasket is a mechanical seal between two objects. It is usually used to prevent pressure, corrosion, and natural expansion and contraction of pipelines from leakage between two objects. Since the machined surface cannot be perfect, the irregularities can be filled with gaskets. Gaskets are usually made of sheet materials, such as paper cushion, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, glass fiber, or plastic polymers (such as polytetrafluoroethylene). Gaskets for certain applications may contain asbestos.

4. Generally, the screw with the nut is fixed in the through-hole, and the diameter of the through-hole is generally slightly larger than that of the screw. Therefore, a gasket is needed to increase the contact area. Protect the parts. Tighten the parts, reduce the pressure, and protect the parts and screws.
