what size bolt? tow bar

hellooo everyone! anybody be able to tell me what size bolt holds a standard towball to the bracket? (not the bracket to the chassis )

Ive got one and it takes a 22mm spanner but don't know if its M16 or M18?
sorry for a bit of a dim engineering question but I don't want to order the wrong ones!

Have a nice day all!

M16

I just usually search Towball bolt, and get an appropriate length.

I saw em on eBay for a couple of quid then went to my local fixings place and got two (with nuts and washers) for less than a £1

Like Tim says, M16.
Be careful to use high tensile steel bolts for the job, theres a heavy tensile load on them while you're towing.

Thank you everybody! I thought it was M16 but wanted to double check.

Its to hold on a NATO hitch that's got quite a bit of weight to it so ill be sure to get high tensile / high breaking point bolts as there's going to be quite a bit of stress put upon the bolts during recovery, I wont be using it to tow anything but none the less needs to be high tensile.

thanks all!

A 22mm spanner size is M14 unless its a specialist bolt

Most tow balls etc take M16 24mm spanner

Dont put a m14 in a m16 hole

might of been 24mm spanner cant remember thanks anyway

nato isn't m16

Having just refitted the towball on my son's D2, I can confirm M16 and 24mm or 15/16" A/F.

it clearly said standard ball

you need part No BH112241L

if it was a 22mm it would be an M14, bot google thinks the BH112241L is an M12.

unless of course its not an actual nato hitch, but one of these nato style hitches, in which case...

M16...

as in these thingys

Where's the Op gone this needs clearing up

Im bacckkk is a 7.5ton big nato hitch, not one of those ones pictured above

I said tow ball as the same bolt fitted the nato but wernt long enough ;-) wanted to check it was m16

Hmm just double checked there is a slight bit of movement. . M17?

Int that one of the hitches off the back of a wagon, and not a 'normal' NATO hitch

I think so, the 4 holes for the bolts are equally spaced out in a square rather than a rectangle, if you see what I mean
