Product Description
Plain washer (or "flat washer") A flat annulus or ring, often of metal, used to spread the load of a screwed fastening. Additionally, a plain washer may be used when the hole is a larger diameter than the fixing nut.
Product Information
- Flat washers prevent the bearing surface from sinking under the load.
- Flat washers can also be used as spacers, as is common in industrial and domestic applications.
- If electrical insulation is needed, use plastic flat washers, as a metal washer will act as conductors.
- Flat washers are used to distribute force or correct a hole size.
- In other words, flat washers are used to increase the screw's bearing surface area.
- This way, the fastened object experiences less surface pressure.
- When the bearing surface sinks under the surface pressure, it can lead to looseness.
