Yes, that part is missing here, having the background of the problem would help. I remembered he had posted about having a broken lug bolt a few days ago and that I had posted the (MF 205) parts book page for him, which shows hex head capscrews and lock washers as original equipment.
While there are other ways to hold the wheel on that the manufacturer's method, in this case he is following the book. If he isn't going to get the M16 "Wheel retaining bolts" and lock washers form Massey Ferguson, there are many options he can consider, as evidenced by the replies thus far.
I would use plated cap screws to lessen rusting. I would likely use grade 10.9, even though he said he found a 7 on some of them.
If I was going to use a "flat" washer I would consider using the metric conical spring washers (which work as lock washers), unless I chose to weld the washer to the rim to reduce the worn hole size. In that case I would use a heavy metric oversize washer (and the cap screws might need to be longer to have full engagement in the threaded holes). McMaster offers a selection of both types.
A blue thread locker will not hurt, regardless of the washer type used. A good coating of the thread locker on both, the cap screws and the hub threads, will keep moisture from the threads and prevent rusting (sometimes better than anti-seize. JMHO
