I’ve got a set of the KoKen in 1/2” drive. The regular ones (14400?)What brand do you guys prefer when it comes to impact sockets? So far I have only seen Koken offering impact sockets.
I got a 3/8" impact gun for Christmas and figure a nice set of sockets would compliment it nicely.



No Japanese tool haul is ever "complete".My Japanese tool haul is complete.
I'm just trying to convince myself that it is...for a couple of months at leastNo Japanese tool haul is ever "complete".

I assumed that was the case, but thought that I'd still prefer it on the regular ratchet. While it works fine, I'll definitely be ordering the larger size whenever I place my next order.@jmf535 you got the wrong size quick spinner for your Nepros 3/8 ratchet. The one you have is designed to better fit the compact head 3/8.
Why not buy Williams if you are so obsessed with American brands?
Agree with you. I use 1/4” drive size more than anything else. I rarely use 1/2”. If I want to try something, I always buy a 1/4” drive size set first as a sample. Also, I find 1/4” to be the least forgiving- if it’s a tight fit there are enough size variances in thickness and length of 1/4” drive size sockets to really see a difference. In terms of size, 3/8 and 1/2 seem much more forgiving from my experience where length and thickness aren’t quite as important/crucial for access to fasteners.
Hi Greg, would you mind answering my 2 questions:I acquired a new gadget, the KTC Torqule. I purchased the 3/8 size after finding out it covers 2Nm- 80Nm. The specs claim 10Nm-80Nm but it starts reading at 0.2 and can be set as low as 2Nm. The 1/4 Torqule range is 2Nm-10 and the 1/2 size covers 20Nm-200Nm.
Rain in the desert provided a unique photo opportunity.
It is a process to get the phone paired and rely only on audio tone to notify. The phone does visually warn you but no one is looking at their phone while torquing something important.
Phone shows set at 6.0 Nm. The yellow line is a live graph, although useless because there is no markings it looks cool.
If you have your phone on mute/vibrate it will not warn you over audio on the phone. However, if paired with a bluetooth speaker it has a nice array of warning noises. No feedback from the device itself is strange and going to take some getting used to.

But those are impacts and I would never use chrome on an impact, personally.
@MrSubaru1387 was definitely a huge influence for me to start looking into Tone and Ko-Ken since I am a Subaru mechanic myself. When Tone released the horizontally opposed spark plug socket/extension I knew I wanted those and I fell down the Amazon Japan rabbit hole really fast.So what got you folks into collecting tools of Japan?
Is there a specific place you go to find them, or is it an exercise in hunt and peck?

I learned of the various Japanese made tools from being on this forum. I have been very impressed with the quality for the price you pay for the tools. As mentioned above we have a few experts here that can help you navigate whatever tool you need.So what got you folks into collecting tools of Japan?

Good choice!I currently have a Tekton 1/4" socket set and would like to get a Koken 3/8" set as a DIY'er. Should I get the regular or Z-Series for general automotive? Price difference isn't much between the two if you consider the magnetic rail which are about $25 if purchased separately.
I'm thinking with starting with these first and will get the nut grippers and spark plug socket in the future.
It seems that Palmac prices just shot up 10% over night on the socket sets or maybe it fluctuates?
Ratchet(s)?
Not familiar with all the models yet but they don't have to be Koken.

3/8" Square Drive Extension Bar Set

Here you go!Dave455: Would like to see photos....



I'd appreciate the photos if you have them. It seems that all the YouTube review videos only showcase the Z-Series.As to which, good question?
If you need any type of socket at all, KoKen probably offer it in the regular range, but there’s only a basic selection in Z Series.
On the other hand, if you want the double universal, that’s only available in Z Series. If you have to mix and match, do so sensibly. I.e. - whatever ratchet you get, get the spinner to match or it will be the wrong size. The Z Series uses a 28mm spinner to match the slimmer ratchet head.
Edit - I have mostly regular, some Z Series, but can take some comparison photo’s if it helps.
Done!I'd appreciate the photos if you have them. It seems that all the YouTube review videos only showcase the Z-Series.
I have an E46 BMW (99-05) and can't recall a repair that needed anything more than basic sockets/wrenches. I just learned about Koken this week but those universal and double universal sockets (as well as nut grippers) would've been super helpful when replacing the starter. It's located just under the manifold on the firewall side and the the service manual tells you to remove the manifold to get access to the top bolt top but we were able to do it from the bottom with a couple of wobble extensions and a regular universal socket.
Thanks!Done!
Yes, it’s worth comparing side by side.
I have two BMW’s of similar vintage. Sometimes I get by with basic tools, sometimes not. Funny you should mention starters, I have a sticky solenoid on one of mine so it’s got to come off, and I know that needs an E Torx, so that’s getting specialised.
I have Stahlwille in my workshop, and that’s generally my go to for automotive work (at least in metric) but I don’t have everything. I have KoKen in my house, and I have invested in probably one of everything I think I might need, so if I need an E Torx or an XZN I know there’s one there.
I find KoKen is good for building up a comprehensive set. The tools are consistent (old and new match), the range is extensive, and I never feel ripped off. I have to say that the dealers are good in the U.K. Unless I want something really odd it’s usually with me next day, which is a life saver if you’re half way through a job and need something.
