Nope, just kidding as they seem to make many esoteric combinations.
I'll guess you saw an AI search result. AI makes up all kinds of garbage. It sees one tiny bit of information on the same page as something else and associates it together.

Then rest assured John, that any size over #4 does not exist.
Kind regards,

I was introduced to this on my '87 Burton Elite 150
I also remember the instructions stating "Tighten as hard as you can." !
Pretty sure that is a joke. Tekton makes some wildly large sizes for 1/4 drive etc. I think they sell to people's compulsion to buy a "full set" even though there are not a lot of uses for large sockets on 1/4 drive that would not break the anvil.

Ski bindings use #3 Pozi.

That looks like a ACR PH3 in the Zephyr bit holder, no?
Your VACO avatar reminded me I have an offset screwdriver PH3/PH4 in that brand.
Choosing a screwdriver is like picking bananas in the grocery store.
Pozidriv #3 screws I come across at work.
I run into PH4's occasionally and have seen where people buggered them up trying to use a PH3 driver. I shared a picture here some time ago of an Apex PH4 1/4 hex bit I was using to access 240v fan mount screws.
Sometimes they show up in unusual places like on the base plate of a woodworking router.
My old Snap-on SSDP-64 Contour Grip PH4 (second below) is actually smaller than the modern PH3 Instinct (first).

Most of the PH4's I see are inside a hex, so I hardly ever use my driver. My PZ3 and PZ4 bits are what fit those Swedish furniture assembly cams best, and I've even run into one cam that took a PZ5.

I’d like to see some PH/PZ5 tools. I’ve never come across them in the wild.

@KnurledNut you imposed some doubt in me so I went and checked, and yes, it’s a P4
I can relate to the situation of people buggering up the larger Phillips sizes. I worked at a shop where we used a lot of 1/4-20’s with countersunk P3 heads and they were always getting destroyed by people with a P2 in their impact.
Honestly I just experienced it the other way too. We were using some #4 hi-low screws on a job last month and my helper stripped a couple P0 drivers before I got involved and realized they wanted a P1.
@rlitman , Swedish cams you say? Maybe I *do* need a PZ3!

Here’s a Snap-On Instinct PZ #4 Snap-On Part# SHDZ84 that some might, or might not, find interesting. I bought the complete set, tray & drivers PZ #1 through #4 back in the day because I come across a lot more PZ than PH, and iirc Snap-On did not have an extended set with slotted, PH AND PZ #1 through #2. So I got the slotted, PH and stubbies set + the PZ set.
Kind regards,

P3's destroyed by P2's are all too common. So aggravating in commercial hardware!

That's a beast of a driver. Lord.
I know there are lots of people that don't care for the instinct handle, but in these larger sizes it's absolutely boss!

When, in a previous life, I worked as a ski binding tech, we saw PZ3 screws trashed by folks using P2 all the time. Even a P3 will trash a PZ3 as the point doesn't seat fully. I don't think the Venn diagram for skiers and wrenches overlaps much.I stand corrected. Thank you sir.

I was sold on the instinct handle because my Snappy offered “screwdriver wrestling”. He had a little sleeve to go over two slotted drivers and challenged you to beat the instinct handle with your favorite screwdriver handle. The grip and transmissible torque instinct handles offer is insane and I absolutely love them.
Surely not for every job, and on the insulated/ non-conductive bit-tipped series they are actually counter productive. But for a lot of other stuff, my favorite handle option.
Kind regards,
Olli
I worked in a couple of ski shops in my youth and don't think I ever saw a PZ3 driver. Always used a P3 with the tip ground back a little. It worked, but you had to be careful.
I was properly amazed when I eventually acquired a gen-you-wine Pozidrive #3. Nothing like the right tool for the job!

A not-so-close approximation of a PZ tip.
I was a Tyrolia binding tech. Tyrolia sent us their "special" tool kit, including the drivers. The drivers were clearly labeled PZ3.
This was the early '90s, when skis suddenly started getting fat... then fatter.... I wonder how many drilling jigs we replaced over that decade?

Just for the sake of sharing less common tools, here's my Torq-Set #0 thru #10 plus #1/4 set. As mentioned above, this was the first thing that came to my mind when the OP started the thread.
I think that Knurlednut is correct. The OP probably meant Torq-set.
I have Torq-set bits in a security bit set. There is a 6, 8, and 10 in my set.

Is that a common fastener on 80's Honda motorcycles?
I don’t know. I thought that they were for NASA/aerospace in high vibration situations.
I do know that I have never used any of mine.
Mine came in a made in USA security bit set.

That is a 3/8” drive x 5/16” (manual impact driver bit size) bit holder. It has a really strong magnet. It can hold up a cup saw arbor through the #4 bit.
I got it years ago at an estate sale.
I have no idea of its original intended use. Maybe it was a tool used in a factory. I think that it is quite old.

This thread lost its topic a long time ago.
Skilcraft products help with the AbilityOne program. Some of these are sourced from Snap-on/Williams. I believe its limited to screwdrivers, sockets and wrenches.
I have a 3/8" 12 point socket set. I bought it and the screwdriver brand new.
Here's pictures I took when I got them several years ago:
The wrenches are Williams Supercombos:
From their website:
"Established in 1938, the AbilityOne® Program is administered by the U.S. AbilityOne Commission®, an independent federal agency. The Program creates employment and training opportunities for people across the country who are blind, low vision, visually impaired, or have other significant disabilities through the sale of SKILCRAFT® and other products and services.
Every dollar spent, whether through the production or purchase of quality products, or of knowledge-based services like IT or contract management support — by both private, commercial companies and the federal government -- meet business needs right here in the United States. AbilityOne solutions offer streamlined acquisitions and cost savings, while providing employment opportunities for people who are blind or have significant disabilities. A 2023 Mathematica study estimated that the AbilityOne Program generates two dollars and 66 cents for every one dollar spent by the federal government.
The AbilityOne Program's authorized enterprises, National Industries for the Blind (NIB) and SourceAmerica, serve as central nonprofit agencies to administer the program and distribute orders among associated nonprofit agencies that are AbilityOne authorized providers. More than 39,000 people with disabilities make up the AbilityOne workforce, including more than 2,500 veterans and wounded warriors."

Edit to add:
Oh, forgot they do some pliers in sets.
I think these are just Williams USA.

Where can I find jis#4 or a jis#5
McMaster-Carr
McMaster-Carr is the complete source for your plant with over 595,000 products. 98% of products ordered ship from stock and deliver same or next day.
Mcmater doesn't list brands but these are the Vessel Megadora drivers. Vessel invented JIS and are pretty much the best.
I have the #3 Impacta, but I have never seen a listing for a Vessel #4 JIS in any of their lines. I have #000-#3 in JIS.
What exactly do you need this for?

I've never seen a #4 jis screw driver either nor have I had the need. I specifically bought a vessel JIS only set and it went from 0 to 3.
As far as use on a motorcycle I've never seen a need for JIS #4 although maybe I guess. Most screws were JIS 2 and occasionally JIS 3 for engine case covers.
Going back to the crux of the issue… what do you need these for?

To see how many responses an absurd question can get?
That's a lot of words for trolling

I bought a T handle #3 for working on Hondas 50 years ago. In all the years since, I have never needed it for anything else.

In a previous post you mentioned needing impact. Is this for a manual hand driver?
Vessel would be a good JIS option for PH4 available at a reasonable price.
Forget #5. You won’t be needing it, nor will you find tools for it.
Even if the OP is trolling, the “hey-look-at-me” one-liners from the peanut gallery really don’t amount to much more. There is beneficial info to be shared that others may learn from. I’ve enjoyed the discussion and appreciate those that contributed useful input.
