I have what I take to be an adjustable quill stem, after some research. I had a bit of an incident in which a wheel temporarily became slightly loose, and I think the angle of the stem somehow moved closer to 180. The handlebars aren't at the right angle. Anyway, I've unscrewed the angle adjusting bolt, but I can't get this thing to budge. What do I do?
pics may help, it sounds like you are trying to loosen the binding bolt thru the side of the pivot. (big no no). you want the bolt in front underneath (On most stems). pics would help.

Not looking familiar, what is this off of and are there any brand markings/
I believe it is a promax stem
it looks like you loosen the right side allen and a toothed washer should release and then move the stem angle and tighten the toothed washer back in

I had read somewhere about a hidden 6mm bolt inside the right or left side that needs to be loosened also. take a closer look, shine a light in the sides
I am thinking take out the right side bolt and inside is a 6mm to loosen?

congratulation's , You are the first person I cannot help! ha. Without seeing it in person and never have used this stem. I am at a bit of a loss. Maybe take it to the local bike shop for the answer. When you find out, post back with the results.

"There's definitely a nut (?) thru which the bolt I insert fits thru. How do I remove it?"
Thread the bolt part way in - leave at least 3mm (1/8 in) clearance, then tap the bolt head with a rubber mallet or hammer with a block of wood to protect the bolt head. I am guessing that the nut will pop out, and you'll be able to move the stem.

I have never been much of a fan of the adjustable stems. (To heavy). most set them and never adjust them again. I would replace it with one of proper rise and extension to suit you. Still would like to know the trick to the one you have though.
