Hello forum members,

I’ve been addressing some Pentax film cameras lately and already have Moody brand JIS head screwdrivers, but interested in other brands you’d recommend in case I purchase a backup set.

But my main question today is in regards to flat head screwdrivers- what brands are recommended, and what size range.

I’ll get even more specific on the next question- I have a loose film counter cover on a Spotmatic with tiny grub screws. I need to replace the tiny grub screws as the heads are damaged from a previous owner trying to tighten them and stripping them, but wondering what size flathead I need for them- I’m assuming .6mm or possibly 1mm, as they look tiny.

Anyone have experience with these grub screws? Is either .6mm or 1mm the right size?

Thanks in advance for your help.

What don't you like about Moody that you would consider other brands? Moody sells a slotted screwdriver set.

I have a 4 driver JIS Moody set and a Craftsman jewelers set I bought in the late 70s (4 slotted, one Philips). The smallest and second smallest slotted screwdriver fits on all the tiny grubs screws on any of the lenses or K1000 that I've encountered. I've never had to use the smallest or largest JIS driver in the set.

I have this set: https://www.ifixit.com/products/mako-driver-kit-64-precision-bits

It includes 4 JIS bits, several small flat/slotted bits, as well as many other useful ones. I've been happy with the quality and the versatility.

I just examined a Spotmatic on my workbench; a 1-mm flathead fits the grub screws without excessive play. 1.5 mm is too big.

With grub screws you can measure the diameter of the screw and use whatever size that will just fit.

Oh, the Moody have been great and I’m happy with the quality. I’m curious however as to other brands that are in good regard, in case I come across a nice deal on an alternative brand.

Do you happen to know the size of the two smallest slotted screwdrivers on your craftsman set?

I prefer Vessel 9902 over Moody Tools:
https://www.amazon.com/Vessel-125610-9902-Precision-Screwdriver/dp/B003BI4IC4
Made in Japan with super hardened and very precise tips
and long enough to have easy access into difficult regions such as inside the battery compartments.
More about them HERE
I have tried many different brands and Moodys aren't bad at all, no question, but if smaller needed, then there are other Vessels as well:
VESSEL Precision Screwdriver Set TD-56 / -0.9, -1.2, -1.8, -2.3, 00, 0
All crossheads are true JIS, Pentax crosshead screws always were and still are JIS and not PH.

If you compare the crosshead heads of Vessels and Moody under a microscope than you understand the difference.

Don't use Wera Kraftform or Wiha! Not JIS but PH. There are some people who believer that PH and JIS are now the same, but this is not the case at all!

Thanks for the recommendation!
Ordered - precisely what I was looking for.

Also, a bit off topic (sorry!), anyone who can suggest a good miniature hand drill and tapping kit (for vintage lens repairs)?

I have this and it is a good miniature hand drill, but maybe expensive to get it to Sweden.

My mistake - I should have written miniature FINGER drill and tapping set (they are truly mini, easily hold with two or three fingers).
But no problem, I'll find them myself. I just wanted to avoid the lemons. And the combined drills and thread taps are harder to find.

Here's a (just an) example of the size of these mini drills-bits:
