This is true!I've got a 1st gen Tacoma also (01' DCab 270k mi), I find that not all the cross/phillips screws are "JIS", it's mixed, at least that's what it really seems like to me. After all it is made in the USA, assembled in Fremont, CA. A number of parts are actually US made. But of course the JIS are a better fit for phillips screws anyway.

Yup I agree, similar experience for me. It was taking off the IAC to clean for me, have the dots (again I got an 01 also, 03-04 don't have em). The screws for the glove box & driver's kick panel or whatever it's called (panel under the steering column) are JIS but I don't think those had the dot, I forget.This is true!
Years ago I was removing the MAF sensor for cleaning on my first Gen 1 Tacoma (a 2001), and I d*mned near stripped the first of two screws before I realized it was JIS -- with dot and everything. Quick like a bunny I switched to one of my Vessel JIS drivers and took both out effortlessly.
JIS only for me since then. They indeed work better for any crosspoint screw.

Been using my ZEAL ratchet with comfort grip for over a year now for oil changes, drain plug removal/reinstallation. The handle gets very dirty and oily. I wipe it off after each change and so far it still looks and feels new.Those of you with Ko-Ken ratchets, how's the comfort grip holding up?
Speaking of the MAF, that reminds me, I too boogered my MAF & IAC screws a bit. Since I take those off somewhat frequently (every year or so), I bought socket head SEM screws for them. Took me a while to figure out what these type of screws were called (captured washers).Years ago I was removing the MAF sensor for cleaning on my first Gen 1 Tacoma (a 2001), and I d*mned near stripped the first of two screws before I realized it was JIS

The Ko-ken Zeal ratchet is not so much of a "comfort" grip as in its not soft rubber/rubberized surface. Its hard plastic that's been chemical/oil resistant in the last 2 years of my not so regular usage (say once a month on average). I would say that i prefer this grip (i have the 3725Z - non-flex head Zeal ratchet in 3/8") for low torque applications as the grip might slip in greasy/oily hands if applying higher torques (which probably is not a concern since you wont be able to apply high torque due to the shorter handle on the Zeal ratchet).
So that's the secret I could not remember. I just sent an inquiry.Are you saying you sent jp-carparts.com a note with those part numbers and had no luck?

In some recent year they tried to address that, but apparently it was a bit much to do. If they did, it'll likely drive up the cost in production.So I've been involved with a construction project from hell (currently in arbitration if that helps explain things). And I've been without my garage for nearly two years.
All my tools are in a storage unit two miles away. Inconvenient. So a lot of my tools are sitting in the corner of my bedroom and for the past two years I've been buying new tools or upgrades to the tool set I have. In the late 80s I bought the classic Craftsman (USA) mechanic set. I've added to it here and there but for the most part it has served me, and my moderate DIYing, very well.
Early this year I spoiled myself with my first ever ratchet purchase in 30+ years + some extra goodies.
All Koken
Koken Z Series 3/8 Ratchet Flex Head 178mm length (my go to ratchet now, even though I'm still getting used to a flex head)
Koken 2725Z 3/8 ratchet in 1/4 body (when I first opened this I laughed at how tiny it is. But I love this ratchet for smaller stuff.)
Koken 3/8 shallow socket set metric
Koken 3756z3/8 Ratchet Quick Spinner
Koken 16mm spark plug socket
When I put these sockets on the Koken ratchets there's very little wiggle, if any at all. It's really impressive coming from 30+ year old Craftsman ratchets and sockets which almost feel like wobble/universal at this point with how much play the anvil/head has.
I love the texture on the socket base. Knurling is always nice but this texture is more subtle and very grippy.
One note that I'm a little disturbed by is the stamping on the sockets. As you can see in the pictures, the alignment is all over the place. Especially noticeable when they are in the socket rail provided with the set (which is really nice). The size stampings point right, point left, off center left, etc. And trust me, I've tried every 90* orientation to line them all up but to no avail. The stampings are off.
Pretty shocked for how extremely tight the tolerances are on everything Koken.
In the end it won't matter because the eventual socket rails I'll be using for organization will have circular posts to place the sockets vs the standard square anvil-like![]()
Those of you with Ko-Ken ratchets, how's the comfort grip holding up? Looking at ordering a 3726Z or a Snap-on hard stubby flex.
I know, completely different price points..
I've had my eye on the Ko-ken Zeal ratchets too. I think I read somewhere that the Zeal ratchets direction selector is "reversed", as in flip to right to tighten/on instead of the usual flip to right to loosen/off?
Can anyone confirm this? I really hope not cause that's a deal breaker for me. I just can't get used to backwards ratchets having been programmed in my brain for so long. I won't use/buy em if they're backwards unless I have no choice.

Awe damn, I guess no Zeal for me. Thanks for confirming.(koken zeal, nepros)
both above are set to tighten (will turn fastener clockwise).
pretty sure all koken ratchets with selector switches work in the same sense, not just zeal.

as i said, i'm basically positive that all koken ratchets are "backwards". even non-zeal.
though many would consider nepros ratchets backwards.![]()

I don't think I have ever payed attention to the lever direction either in all of my 45 + years of using ratchets. As Pizza said if it's not turning in the direction I need I just flip it the other way.it actually doesn't bother me because i don't have it memorized.
my thought process: set the wrong way? flip the selector switch.
JIS only for me since then. They indeed work better for any crosspoint screw.
I have heard that repeated a few times, often by people who haven't used Japanese crosshead drivers.I believe ISO or DIN standard new Phillips screwdrivers are all compatible with JIS nowadays too (and Vessel screwdrivers are also made to the DIN/ISO standard).
I'm not entirely sure, but I believe the screwdrivers made to the ANSI/original Phillips standard sold in the US are the only problematic ones today.
Yep, I believe you have that exactly right, @F-22. It’s probably not strictly correct to call any current Vessel driver JIS at all, as the original crosspoint Japan Industrial Standard has been withdrawn as far as I know.I believe ISO or DIN standard new Phillips screwdrivers are all compatible with JIS nowadays too (and Vessel screwdrivers are also made to the DIN/ISO standard).

Yep, my basic Ko-ken 1/4" set (not Zeal), includes a backwards ratchet. I have several other 1/4" ratchets that I use instead, not because the Ko-ken is backwards, but because I prefer the other brands' designs (Wera roto head, Nepros regular and flex head, and Hazet T-handle).pretty sure all koken ratchets with selector switches work in the same sense, not just zeal.
I love it lol. Koken's switch convention actually makes more sense to me, although I never check it while working.Ko-ken selectors are the right way, every one else who uses the opposite is "backwards" LoL
Ko-ken ratchets are the only ones i use and even with these, i dont "remember" the selector switch orientation, i just check if the ratchet is set for clockwise or anti-clockwise in the few seconds time it takes to grab it and put the socket on then apply it on the fastener. It shouldn't be a big deal IMO.

Try and get the KTC wrenches, that way you know country of origin. Tone can be tricky. see link below.Inflation *****, but I noticed that the US dollar hasn't been this strong against the Japanese yen since pre 2000...
I think I can cobble together a "complete" set of Tone "super long" aviation style (0 offset) wrenches for $66. These are cheaper than Taiwan offerings... are these made in Taiwan? Any feedback?
Any other brands I should look out for like KTC? Looking to place my first Amazon Japan order...
Thanks will go for the KTC's even though I prefer the satin finish of the Tone's.Try and get the KTC wrenches, that way you know country of origin. Tone can be tricky. see link below.
AND, Koken ratchets are backwards. I had never thought about switch orientation but when I first started using Koken it is one of the first thing I noticed. Like most, I grew up on craftsman. We might not memorize what way the switch is facing but it’s been ingrained in our brains since the first the we used a ratchet.
Those KTC wrenches have a satin finish alsoThanks will go for the KTC's even though I prefer the satin finish of the Tone's.
Even better. Thought I saw glass in the description. Many thanks for the input.Those KTC wrenches have a satin finish also
I have noticed that double box end wrenches are often called "glasses" wrenches or spanners in japan, i.e. that they look like a pair of spectacles.Even better. Thought I saw glass in the description. Many thanks for the input.
Good to know. Here I was thinking and wrongfully assuming, that glasses was referring to a mirror like finish. Also looked a few pages back and another member recently purchased said wrenches. Definitely satin.I have noticed that double box end wrenches are often called "glasses" wrenches or spanners in japan, i.e. that they look like a pair of spectacles.
I've only opened a handful of laptops, having mostly encountered Japanese screws when working on synths / tape decks / amps etc. I don't remember ever having a problem with Wiha or other European precision drivers.I'm not sure what you are referring to when you say general electric screws but I used to work in electronic repair. That company only purchased tools for the techs from vendors they normally buy from. So Wiha was one of the main tool brands we used.
Laptops & other mobile devices pretty much always used "JIS" screws, Wiha precision screwdrivers & bits didn't fit them well but it's what the company classified as quality tools so that's what we got. I tried to explain the whole "JIS" thing but of course no one was gonna listen or go through the trouble of sourcing the tools.
