"Very sturdy washer pressed from 2mm steel and plated. However nowhere on the Screwfix website does it say what size they are, and they are about half the size I wanted. For anyone thinking of buying them they are 24mm in diameter."
"Washers are packaged in a bag in an individual box, which is completely over the top for 10No washers. Screwfix should pick them from a card in a display in store Washer dia should be displayed as these were too small for their intended use & had to go out to DIY store to purchase more"
