Got to buy a large socket to undo the main pivot bolt on a Strimech shear grab.

Got to be a socket no spanner or stilsons will get near it, I measured the nut as being just over 56mm some thing like 56.3 or 56.4mm? (digital veneers so should be accurate)

Would they have used a imperial bolt???? what size imperial socket is near that?

biggest socket I got is 51mm so no were near!

Need to take the top grab off to do a little repair:mad:

Of cause I might just be over thinking it and it is in fact a 56mm? are bolt hexs and sockets that close a fit when you get to really big sizes? don't want to go ordering a 56mm to find it don't fit!

Could you get your local profile cutting place to cut a hex out of very thick plate, then cut a circle round the hex shaped hole, giving you the start of a socket, then some plate welded on top of that and an old socket on that? Would be a lot cheaper than a 2 1/4 inch socket.

2and a quarter inch I'd say 2.250" ,the large 1" square drive sets only have a choice of 55 or 58mm it seems

3/4 drive ideally don't have 1"

ebay have some 3/4 drive sockets in 56mm cheap enough but I wonder if they will be okay and have enough slack to fit a 56.3mm nut? guess it would hammer on:D
