Quick Release Skewer Locks?

With bolt-on wheels you don't have LH threads on the left and they are
pretty secure but it's because you're tightening the nuts with a wrench
that gives you enough torque to get them very tight.

I started cycling when quick release levers were beyond my tiny budget.
My bike had the large wing nuts instead:

I don't recall any problems, despite no use of a wrench.

Those wing nuts are still used in L'Eroica events, where riders use old
equipment and often ride gravel roads, emulating rides of days gone by.

If there are problems with the wing nuts, they're not mentioned in the
relevant articles.

But there is no anti-theft benefit to wing nuts, unless your criminal population is exceptionally old and suffers from arthritis or general weakness.

I wasn't addressing theft protection. My point was that, contrary to
SMS's statement, it's not necessary to have a wrench to get enough
torque to keep the front axle in place.

Generally, gravity keeps the axle in place by pushing the closed end of
the dropout's slot down onto the top of the axle. Under normal
circumstances, the axle nuts or quick release levers need to prevent
motion only when the wheel is up in the air. During that time, the load
is merely the weight of the wheel.

That's assuming, of course, that one doesn't have ejection forces caused
by a disc brake being applied.

FWIW, one relatively inexpensive way to slow down thieves is to just get a couple of stainless steel hose clamps and wrap them with tape, heatshrink or some inner tube, then tighten them down over the QR levers. You can often turn them into a position which makes it harder to access the screw slot (some are hex and you could grind the slot down, meaning you need a socket to remove). Not theft-proof, but it will require a few minutes of work and perhaps attract attention. Better than nothing and cheap

For now she took along a thick cable to use in conjunction with a U lock.

Hopefully the U lock is not as old as the technium and can't be picked with a bic pen-

LOL. It's not a Kryptonite brand lock.

I'll be sad if the Technium gets stolen. It's less than 40 years old. I
replaced the wheels when one was wrecked. I replaced the stem when my
son was riding it because the size of the frame, while perfect for him
in the world of "compact" frames, was really too small in the world of
properly sized frames. But it fits my daughter well as a non-compact.
