Proto Metric ASD combo wrenches - skips?

[davethorik]

Perusing CL, found an ad for a "15 pc Proto Metric wrench set, 7-32mm."

The set skipped a lot of sizes, and I just figured seller had lost them or something.

Turns out, it is an actual Proto wrench set. J1200P-MASD.

Includes: 7, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 29, 30, 32.

am I missing something here? Why make a set that is basically 7-32 with even sizes only (except 7 and 29)?

On European farm equipment made from the 90's to present I have only needed 7, 9, 10, 13, 14, 17, 18, 19, 21, 22, 24, 27, 30

13 sizes vs. 15 but different combination. Maybe some Asian equipment or machine tools that is used here in North America.

It could also be a government set from the pre GMTK days.

That makes no sense to me either; whatever system you're working in (JIS, SAE, DIN, etc.), it skips important sizes.

It's a mystery.

Yeah, 'cause I'd much rather have a 26 and 29 than a 13 and a 15...

Needs 13, 15, 17 and 21,, might be able to do 21 with 7/8,, cant remember but those other sizes is why I would want the set.

22mm is close to 7/8":

13/16" = 0.8125"
21 mm = 0.8268" (+0.0143" = +1.76%)

22mm = 0.8661"
7/ 8 in = 0.8750" (+0.0089" = +1.02%)

Thanks for the sanity check, fellas. A true wtf that is a catalog set.
