Descriptions

• A standard flat square washer with a hole that is normally in the centre. 
• Used for two main reasons: 
  • To minimise scouring or scratch damage to mating material as a result of nut rotation
  • To increase the effective bearing surface of the bolt or nut. That is, to distribute the load of a threaded fastener over a larger area and prevent deformation of the bearing surfaces. 
• Made of mild steel
• Available in Hot-Dip Galvanised,  Yellow Zinc finish.
