I don’t have the Wera Tool Check Plus. I might acquire one at some point, as I think they’re a good option for a road box.
I do have the set shown below.
Perhaps I can clear up some misconceptions.
Wera may be a German company, but they don’t make tools in Germany, and haven’t done so for the best part of 30 years.
Their screwdrivers, hex keys, torx keys and screwdriver bits are all made in the Czech Republic. They have been since the “Kraftform” drivers were introduced.
Wera were not, historically, a maker of wrenches or sockets. These are a relatively new line for the company, and are made in Taiwan. Again, they always have been.
Wera’s design is very good. You may not agree with everything that they do, but they try.
The Czech factory is not some “outsource to the lowest bidder” deal, but is actually Wera’s factory. The Czech’s can produce very decent stuff, and the Czech Wera is excellent in my opinion. The steel is good, manufacture likewise, and quality control excellent.
I have a lot of hex keys and screwdriver bits, and consider the former second only to PB Swiss. Wera offer a greater variety.
The Zyklop ratchet’s are made in the Czech republic, but all sockets, extensions and mini ratchets are made in Taiwan. There is still some “so so” stuff coming out of Taiwan, but Wera isn’t it. It’s up there with the best of Taiwanese, such as Facom, but differs in design and finish.
It’s good and durable. This 13mm socket has seen a good deal of use and there’s no real wear.
I reckon the best tools Wera produce are their hex and torx sockets. The socket bodies are made in Taiwan, the blades in the Czech Republic and they are superb. These 1/4’ drive long bits are my newest.
Bear in mind though, that in the U.K. and Europe, Wera tools are “mid price”. If you’re shipping them a long way and paying top dollar, there may be other options that represent better value.
Edit - both DIN and ISO standard bolts use hex sizes of 5.5, 7, 8, 10, and 13 for bolts of 3, 4, 5, 6 and 8mm. 11 is the standard size for 7mm bolts. This is uncommon, but that’s why it was included in some sets. 12mm is a JIS size, but probably more common than 11mm.
