mystery bolt

[blindstar]

My wife found this bolt in our driveway (1/2 mile gravel). I believe that it is a M16-2.0x65. I maintain the road with my L4330. This time of year, with a front mounted snowblower. Any thoughts on where this may have come from would be greatly appreciated.

Coarse thread means probably nothing to do with your wheels. Likewise loader to cast chassis mount - I think KUB uses a finer thread? - - Any wear marks on the bolt shank or threads?

When I find items like this in my driveway, my first thought/hope is "I bet it was in the rock when the dump truck left the quarry".

I would check all the wheels and loader mounts to see if you're missing a bolt there.

30 years ago I was building a condo project in a suburb of San Diego. We needed a hundred thousand yards of fill and hired a grading contractor to supply. The contractor was also doing a project for a high rise in downtown that had large excavation for underground parking. The sandy soil was loaded onto bottom dump truck, transported about 30 miles to my site, dumped in windrows and then spread with heavy equipment.

I was walking the site with my engineer when we found a antique glass light bulb laying on the surface totally intact. Do not ask me how that could possibly have happened! We found other antique items that were probably disposed from maybe a hundred years ago also.

it's one like this, it could last at least 117 years, and it must be worth something!. Livermore's Centennial Light Bulb

Yeah. OP said 2mm pitch. It looks finer than that - but at 16mm D that could be deceptive. Wheels/loader is a good call.
