Screw/bolt/nut lookup facility

Does anyone know of any website or catalogue where you can look up the size of bolts and nuts etc? My local indy spares dealer seems to have access to a system where they can pop in the part number and it tells them the size. I’d like to do the same so I don’t end up paying £5 for a 5p bolt.

I usually get part number then go on to Britcar here https://www.brit-car.co.uk/search.p..._type=&xSupplierID=&product-sort=&xPerPage=10 type part number in and 9 times out of ten they have the size there, like this one M8 X 20MM
My local bolt nut and bolt supplier always has what I need at half the price.

Cheers chap, I’ve just tried that for a couple of missing set screws and it came up trumps.

Took me a while to figure it out but Britcar gives you the size nearly every time
