Bottom Bracket Thread Type - this must match the thread of your bottom bracket for the lockring to fit.
Thread Direction - most bottom brackets only have an adjustable cup on the non-driveside of the bike, so lockrings mostly thread to the right (clockwise), regardless of the thread type. However, some bottom brackets have adjustable cups on both sides so the thread direction may be different.
Thickness - this is rounded to the nearest 0.5 mm.

Bottom Bracket Type - ‘square taper’, as the name suggests have square shaped axle ends that slot into the chainset and ‘cottered’ axles are round and secured by pins - pretty much every bike up until the 1990s would use one of these, cottered being the much earlier system.
Thread Type - this must match the bottom bracket thread on your frame. The 3 common thread types on classic and vintage bikes are English (also known as British or ISO), Italian & French, and are usually (not always!) found on frames built in their respective countries. If you're replacing cups, they often have the thread type stamped on one of them, if not there are a couple of things to look at; bottom bracket shell width (English & French = 68 mm, Italian = 70 mm) & drive side cup thread direction (English = left, Italian & French = right). The only curveball to watch out for here, although pretty uncommon, are Swiss threads (also found on some French frames, Motobecanes being one) which will have the same shell width & thread direction as an English thread frame but the actual thread pitch will be different. If none of the above matches what you have, there are a few lesser known varieties that will require some further research.
