Secotec Square Washer DIN436 M 10 Galvanised Blue KP 50 Pack of 50 – 442370

out of 2 boxes of 50 there are about 20 total that looked like the picture with rounded edges, these were the ones i wanted although as it happens they were only 2mm thick not 3mm as described. the rest were poorly made, not square and with holes off centre although they were 3mm thick. will have to make do with just the 20 that have round edges, meaning they will have cost me over a pound each as the rest are rubbish.

Just the job!
