Does anyone make 6pt offset (45* to 60* offset) wrenches? Are these only available as complete sets? I need a 10mm.
Offset 6pt wrench?

Tight fit area, so a ratcheting wrench won't work as there isn't enough room around the bolt head.
The SK Tools looks good - except for the price! I may end up having to reduce the outside diameter of the wrench to get it to fit. Would hate to do that with a $36 wrench. But good to know that option is there if all else fails, thanks.

If you only need 10 mm take a look at brake bleeding wrenches. They're 6 point, offset, and not too pricey.
Of course, there's no real reason to use six point if you use a quality 12 point wrench with off corner engagement.

KTC, a Japanese manufacturer, has a 45* x 10* style offset wrench. I have a 10 and 12mm wrench. part# for the 10mm is: m27-10h
Check this link for pictures: https://picclick.fr/6-point-hex-box-end-wrench-ring-spanner-253597494865.html
Unlike those SK's shown above, the wrench has the same size on both ends and that's so that the wrench can be worked on even in confined spaces. The hex is broached at a 15* offset from eachother, allowing the wrench to be used like a standard 12pt wrench.
The boxed ends also have minimal chamfer to provide more surface area engagement against the fastener.
Check out KTC's product page (listed at the very bottom, with dimensional specs): https://ktc.jp/files/pdf/dl_catalog/39/276.pdf

Yep, excellent wrenches.

I have a full set of the SK 6pt offset wrenches linked above and they're fine, if a little short. Good for tight areas.

Great idea!
What are examples of 12pt wrenches with off corner engagement?Of course, there's no real reason to use six point if you use a quality 12 point wrench with off corner engagement.

Bonney Lobular, Snap On Flank drive, Wright Grip, Proto ASD
A little better price for you: https://www.harryepstein.com/index.php/wrenches-box-end-wrenches-28002.html
We should probably spell out Kyoto so they don't get confused with the Taiwanese KTC Auto Tools. A fairly obvious attempt to copy a known higher end brand name.

While all these wrenches do have box end off corner engagement, "Wright Grip" and "Proto ASD" refer to the modified open end.
Wright refers to their patented 12 point design as "Wright Drive".
Proto box ends incorporate the "TorquePlus" system.
Just being particular because this is GJ and thats what we do.

There's a lot of "code names" for the various off-corner engagement/radius corners.
Matco calls their's "OptiTorque"
SK calls their's "SureGrip"
MAC calls theirs "Knuckle Saver"
I think GearWrench was calling their's "SurfaceDrive" but I don't see references to that on their site now, just "off-corner engagement" or "off-corner loading"
I could have sworn that I saw a "code name" for the same feature for Armstrong and Craftsman (not necessarily the same name), but for the life of me, I can't find reference to it right now.

MAC calls theirs macdrive and will have an R at the end of the part number reflecting the new "Revised" design. "Knuckle Saver" refers to their open ends.

I like six point for fasteners that I don't want to mark up. I actually ordered Snap On 6 points with non flank drive open ends.
I second the bleeder wrench, or buy a used/cheaper 6 point and heat it up, then bend to shape. You can grind the outside for clearance kind of like this wrench I made.

I’m glad to see someone else is in need of a similar wrench. I’ve been needing some sort of offset 10mm that I’d likely have to modify as well. For a drain plug on a gearbox for a John Deere 569 round baler.
