Thread nut into screw. Use cutoff blade on dremel or equivalent, while holding the screw with a vise-grip on the nut. Then use dremel to smooth off end of screw. Then unscrew nut, which will thread out the end of the screw. Done.

OK, add "with no access to a dremel."

"handheld grinder w/ cutoff blade, vise grips"

Yes. Also sand/file the tip down after you cut the tip off

Those screws look way long, just buy shorter machine screws at a hardware store. No tools needed!

They're just a bit too long. Thick outer door in this case.
Ya know, I think I may have one of those Harbor Freight assortment kits of machine screws kicking around.
But I also found one of those Harbor Freight assortment kits of Dremel cutoff blades. Partially used... by me. I think there was a "left" dremel tool in my garage that must be at my rental building.
And then my eyes landed on the cordless angle grinder and I couldn't hold back any longer. The screws go in fine with rough edges and with having whacked the 'needed' threads a few times. Kitchen floor apparently has some sort of flame-retardant coating. Angle grinder goes with to install the rest of the locks tomorrow...

hacksaw

Tried two metal hacksaw blades and they barely put a scratch in the screws.

Most hardware on locks are made out of hardened metal!

Hmmm..... what a pain. Next time I'll look for ones that are easier to cut with standard tools.

I believe those long, threaded sections would technically be "bolts", not screws; as the thread is constant throughout their length.

There appears to be a groove in the bolts? Some bolts have a groove like that that will create a break point to shorten the bolt.

You'd think, but they are definitely not geared to be easily broken. I think the assumption is that anyone installing locks is going to have access to tools that can handle it. After taking a whack with a hacksaw I'm pretty sure I only would have ruined my tin snips.

The two *generally* defining differences between "machine screws" and "bolts" are *generally* based on size and/or application. Both have "uniform threads" (which is what you were referring to), as opposed to a pointy ended wood screw. Machine screws are generally smaller, usually 1/4" and under in diameter, whereas bolts are generally larger, usually 1/4" and above in diameter; which leads to the second criteria, application. Machine screws are generally installed and tightened by twisting the head, and bolts are generally installed and tightened by twisting the nut that secures it. Internally secured vs. externally secured. Based on the photos and diagrams and application of Black's lock, the threaded piece in question in this thread would *generally* be accepted to be a machine screw, but if it floats your boat to call it a bolt, go for it. Every lock installation diagram I can remember seeing calls those "bolts", "screws", but frankly, the difference between bolts and screws to non-engineering types is ambiguous enough that it really doesn't make any real difference anyway. :-)

...as long as the project is successfully completed... and secure.

I use the layman's definition- a screwdriver is generally not used with bolts, which generally require wrenches or sockets.

Maybe they exist, but I've not seen a lockset requiring wrenches or sockets.

In a pinch maybe a filler or shim could be used until the right screws are found, even a thickness or two of cardboard?

Unless the door is an unusual dimension, somebody makes the right kit for it, so the right screws should be available. Maybe there's a locksmith not too far away who could advise?

Turn the blade around or maybe try teeth down ?
