That is an everyday item in the USA. Every hardware store and fastener supplier has them in every head imaginable. The tough part is trying to find someone to ship them to you.
Peter, it sounds like you have this solved. I was going to suggest searching for a Caterpillar dealer serving your area. Among the parts they sell, bolts and other hardware are included. For example, part number 2J3565 is a 3/8 - 16 hex head bolt 2 3/8 inches long.

Unless you're replacing existing bolts in threaded holes, why not just use an M10 x 50 hex bolt, there's only .5 mm difference in diameter?

I am, unfortunately. I do have M10s as .10, .25 and .50 and had thought of that.
Peter, here is my go-to site for bolts:

Thank you for that. I fear the postage to Croatia would be a killer.
I heard back from the local Caterpillar agent. Unfortunately, they were no longer available. Fortunately, my die has now turned up.
Cheers

That size should be the local hardware store. Mc master Carr will have them but you will have to get had dozen or so. I got something similar on Amazon but in stainless. The ones have are shorter as I was using them to mount a vice on my mil table mine are shorter or I’d offer them . Usually even the home stores have nut and bolt selections grade 8 are a little harder to get . We have a tractor supply store that sells grade 8 bolts like that by the pound if I could get to the shop I probably have a handful. Even auto parts stores have small selection of nuts and bolts around that size.

Sorry I missed thebmetric
I'm happy to ship you some bolts, I have a drawer or two of them - look up shipping at www.usps.com, and if you think it's reasonable mesage me. I may have both hex head, fillister head, allen cap screw and stove bolt types, I don't know until I look and I won't look until you ask.
Thank you, but minimum appears to be 40 bucks !
Anything around here is metric. I will ask around at construction equipment people. Some of them may have UNC bolts if they repair American equipment.
Cheers

Thank you ! It seems to be. I've found an Italian manufacturer Cart but even their shipping seems excessive. I´m checking to see if Harleys use them with the Croatian Harley Davidson agent. I´ll probably wind up making them !
Cheers
Peter
Update !
Thank you all for your help. I wound up making two. Inevitably, once I had done so, sources appeared. The CAT guys turned out to have reasonably priced 3¨ ones in stock in Zagreb and which are coming. A vintage military place in Germany had reasonably priced ones but absurd shipping. (67cents for the bolts and Eur17 to post them)

Bolts: the 3/8"-16 size is common to both UN series and Whitworth. The thread angles differ: UN series is 60 degrees and Whitworth is 55 degrees (rounded). It may be that Whitworth may be very easily obtainable from the UK. Certainly here in Australia, 3/8" Whitworth bolts are very available and, as a hardware item, they are often 'marketed' as 10mm. There seems to be a bit of an impasse here in Oz: nobody has really come down in favour of one system or another, so where we had Whitworth or UN, there's now also metric. All are commonly available.
When I traveled in the UK (between Manchester, North Wales & Scotland) speed limits were in MPH, overpass clearances were in feet & inches and distances (particularly on a turn-off) were in meters. The folks I worked with would often refer to the dimensions of thick woven friction as width in inches and thickness in mm.
In the U.S., aside from those of us directly involved in attaching things to one another, the average citizen rarely knows the difference between a bolt and a screw (and in some cases a nut).

Where I used to work doing repair and maintenance work among other things, some of the men had a hard time with nut and bolt sizes, sometimes I had to order items for them as they were confused about sizes.? and that was not even getting into mm sizes.
