Boltstore M6 x 25 Mudguard Penny Flat Washers from A2 Stainless Steel BS4320 (Pack of 100)

just washers, god selection at the right price

What can I say,do the job perfectly and were reasonably priced.

Check size before buying not a penny washer that I remember

I bought these to fix roofing felt around my shed to direct rainwater into the gutters.

very good did the job well

Decent washers, though there are quite a few inconsistencies in thickness. Doesnt matter all that much for radiator brackets. But if you need them for precision you may be weeding about a quarter out.

Exactly as they should be.

These are great - I must buy some more! I seem to use them for almost everything.
