It would appear that the bolt is a proprietary item (made by the wiper company or for them) but should be possible to "Rube Goldberg" a bolt yourself if you have a grinder, be it a 4-1/2"angle grinder or bench grinder and a Vernier calipers for measuring.
I would use a stainless steel bolt and a "Nylock" locking nut. Get the bolt & nut from Fastenal (they most likely won't even charge you for the parts, seeing as how the paperwork would cost more than the sale.
