Are KMC-Z chains directional?

My last Shimano chain is worn so I'll be trying the first KMC-Z72
8-speed chain on my road bike next week, since Jay recommended those.
Are they directional? The package doesn't say and the Internet doesn't
either.

I don't think that roller chains are directional, are they?

No.

Correction there are Shimano chains that are directional, the CN-HG54,
CN-HG701-11, CN-HG601-11, and probably others. KMC apparently makes no
directional chains.

This article doesn't mention KMC, but does mention that SRAM chains
are not directional, while some Shimano chains are directional. The
article suggests that directional chains have the logo stamped only on
one side of the chain, which should be facing away from the frame:

I couldn't find a data sheet on the KMC Z-72. Everywhere I look, all
I find are "discontinued" or "otto stock" (except some old stock on
eBay).

KMC chains are not directional, and I doubt that even Shimano makes direction 8sp chains. Its a marketing ploy for the high end groups, IMO. I went out and looked at my own Shimano chain -- which is directional -- and I mounted it in the right direction, except for the quick link. I wasn't watching the arrow, which is pointing in the wrong direction -- and probably accounts for my slowness.

Those were not, nor are the newer Z8

Some designs, yes.

Frank is the mechanical engineer. You'd think that he might have something to say about this rather than he far left comments about discrimination where none ever existed.

Thanks, Andrew. Here's hoping the cassette will arrive some day. Fedex
simply declared an "exception" and said it will be stuck in Michigan at
least until the weekend. So I hope the old chain makes it another 100mi.
