The square hole in the plate washer is placed over the square section at the base of the bolt. This prevents rotation when tightening, whilst still allowing lateral movement of the bolt. The lining up of the stanchion base plate is therefore much easier.

We also manufacture specials to meetyour specification. These can be almost any thickness, size or shape.
