So I'm wiring a new residential home. In the garage / workshop they have about eight 50 amp 220 volt outlets going in. These outlets are to be recessed in the wall. What would you guys use for a box for these? I was thinking about using a 4 11/16 box but I don't know if I can find them with side mount for a stud

You can screw the box directly to the side of the stud if location isn't an issue. If you need to be between the two studs then a stud bracket like Dave mentioned will work.

Meaning they aren't in stock somewhere?
 
Wow...eight 50A 220V outlets...I'm thinking here...2 electric cars, 1 OMG air compressor...what else?
 
Is it 2020 NEC? (8) 2 pole 50A GFCI breakers = $$$$$$$$ :) I'm a conduit guy. I would run it in EMT so I could use #8 THHN/THWN-2. You could use 4" sq. or 4 11/16" sq. boxes w/ 2 gang mud rings. Caddy TSGB16 brackets or Caddy TSRBS1625 brackets. Should be shorts runs of pipe if the panel is in the garage.

If you're using conduit and individual conductors, a 4x4x2/1/8" box with brackets would work with #8 conductors. Should be plenty of room unless you're daisy chaining from each box.

These boxes include a cable clamp for larger cables.

I'm not a huge an of plastic boxes with large receptacles, especially if they are plugged and unplugged often. I've had to replace two broken plastic boxes with 50A plugs, and it wasn't a pleasant experience either time. Probably OK for a stove or dryer that gets plugged in once and left alone for decades, but I'd lean towards metal boxes in a garage/shop environment. That's just me though.

Allied makes a decent two gang deep non adjustable plastic box.
As someone else mentioned you could secure your 4-11/16" box directly to the stud or install a wood block behind it and secure to that with a two gang plaster ring.
