I have two wheelchairs with an EZ Lock bracket on the bottom. Each uses a 5/8" coarse thread bolt. I buy them in a variety of lengths so that I can use the shortest one that will still engage with the EZ Lock locking base in my van.
I buy mine from Ace Hardware. The ones I find there are threaded for their entire length. The true EZ Lock bolts are not threaded for the portion that would engage with the EZ Lock locking base in a van. This should theoretically reduce the wear on the EZ Lock base, but I have found that in 6 years the wear is not objectionable using bolts threaded for their full length.
I get grade 5 bolts.
These bolts are locked in place with a nut. Thread the nut on the bolt, grease the threads that will engage with the EZ Lock bracket (to prevent the bolt from seizing), screw the bolt into the EZ Lock bracket an appropriate amount (in my case, as far as it will go), and then finally tighten the nut up against the EZ Lock bracket. This will keep the bolt from rattling loose and falling out.
We often remove the bolt when I am going to traverse more adventurous terrain. An 8" long adjustable wrench works great for installing and removing the bolt.
