Would a "modern", good quality screwdriver set be JIS compatible?

BrianShaw · Aug 26, 2020

Umm, errr... in this thread the advice was for a member in “Eastern MA”, which is in the United States not Germany.

Also... being member of an ISO committee and manufacturing to ISO specifications are two totally different things. One would hope there is a correlation but without a specific product conformity certification that would be merely an assumption or hope.

Hopefully this is not hijacking the thread, since it is a similar question, but I am having difficulty finding a flat head screwdriver that is sharp enough for older cameras such as the Ikontas. I bought the tiniest one I could find on Amazon, but it just would barely fit into the slot... it is almost like you need a razor sharp flat-head screwdriver. Does anyone have any recommendations for this?

Look on a watch supply site. They will have better screwdrivers with thinner blades. Or, home one of your blades thinner using a whetstone.

AgX... probably not if general interest or utility but because you seem to care so much... here’s some detailed info on screwdriver standardization:

the applicable iso technical committee is TC29 SC10

DIN, the German Standardation organization, is Secretariate

each member nation has 1 vote

JIS is not currently in TC29 SC10 as either Participant or Observer.

jIS does not currently have a Standardation category for fasteners or fastening devices that I could find. JIS B 4633:1998 appears to still be active and current, but when standards get past 5 years without update that usually means the committee vaporized for one reason or another.

interestingly, DIN has a standardization committee for sex toys... Which must make GER far more progressive than many other first-world countries.

My advice: make them yourself.

The question is put in a generic way, not as an inquiry on availability.

my, my, you corrected me again... let me re-state, hopefully to your satisfaction this time: Umm, errr... in this thread the generic enquiry was by a member in “Eastern MA”, which is in the United States not Germany. LOL

At none of the german manufacturers catalogs (and I hint to those as these are many members even outside Germany who will find at those products at the racks) I find statemens of ISO specification. The jints at Japan are vague,
The use of the designation Philips already shows what variation there is.

What counts is the actual fit as best as one can establish. For real acute evaluation one must grind down screw heads and check under a microscope.

A few times wrongly used and all we talk about here is blah-blah anyway...

The OP's question is about compatibility, not about availability. It applies to any member in the world interested in screwdrivers.

Thanks - I don't know why such simple solutions don't come to my mind.

Flat blades can be thinned with a few stroke on a sharpening stone. Keep the newly sharpened edge at the same angle as best you can.
You aren't going to need 1000 grit but it won't hurt, just a bit more elbow grease.

Now I am all upset. Is my 1970 Victorinox Swiss Army knife obsolete?

That little flathead at the tip of the can/bottle opener is still the best.

BrianShaw · Aug 26, 2020

Indeed!

Wow... thanks. Looking forward to reading it. One of my favorite books was Petroski’s “The Pencil”. More people should learn about the history and engineering behind commonplace objects that often get taken for granted.

jacaquarie · Aug 27, 2020

Looks as if I have even more reading to do, have ordered 4 of Petroski's books.

The Swiss Knife will always be part of my daily carry, right into the 'afterlife' if need be...

Thanks for posting our blog post! Glad to see it was helpful for you. We got a lot of traffic to our website so I was able to trace it back to here.

Concerning the "JIS" designation and it being unknown over here, I just checked the 2003 Euro catalog from Micro-Tools (who likely were/are the major supplierof camera-repair utensils. It got over 16 A4 pages on screwdrivers, and not one mentioning of "JIS"!
Only one model, made in Japan, is described as being specially formed and often fitting better than type Philips on camera screws. These ones however got a logo, that shows the classic Philips cross-cut, whereas as the Wiha ones, which made up the major part of their offer, got as logo the JIS cross-cut...

Would a "modern", good quality screwdriver set be JIS compatible?
