The bolts attaching my Velorex to my R75/5 are worn out. Trying to find a local source, but have struck out with Lowes and Tractor Supply Company. The bolt is an M12 with a hole on the end for a castle nut and cotter pin. I can't find the bolts online, other than the Velorex site, and I'm apparently not Googling them correctly. Any recommendations on where to look?

McMaster-Carr has metric bolts. You probably won't find them with holes, however. It's easy enough to drill a hoole or perhaps use a Ny-loc nut.

Get the M12 8.8 Grade bolts with 8.8 nylock nuts from Lowe's. That's what we replace with.
The old school castle nuts are only good for one torquing anyway. The second time you line them up they will be too loose.

Aren't the Nylocks only good for one time as well? I have to be able to take the rig apart for storage - doesn't fit through the shed door as a unit anymore.

If you are talking aircraft probably so. Plus there are rules about how many exposed threads can be out past the end of the nut as too many arew said to wear out the locking capabilities......etc...blah blah
However, if you do the research at McMaster you will see some advertized as being reusable.
Most use nylocks over and over. Few have any issues. All of us should check tightenss of fasteners from time to time anyhow. If this is not acceptable to you then just buy extra nuts.
If this bothers you then maybe you could just get a longer bolt and use double nuts on it to lock things. If the outside nut is a acorn nut it looks kinda cool.
Nylocks may be used over a time or two. It's also a good idea to maks sure that you have washers under the bolt head and nut to make the installation more secure. A torque wrench will get them to the proper tightness. You need to have a thread ot two showing on any bolt to make sure that you have full contact in the threads as well.
As far as Nylocks, they are inexpensive and you can do like I do, get a bunch of them and segregate them in trays for easy access.
Ok, I'll see what I can find at Lowes today. It's always an adventure trying to find things in their drawers here - seems that people don't like to put things back where they found them.
