As far as I know all 3/8 chain is really 0.365" or thereabouts. The lo pro chain uses a different "tooth" shape on drive and tip sprockets, as the chain chassis is different. Effectively the tie strap sits lower and the drive tang is different. Low pro bar tip teeth have a flattened off shape as opposed to the pointy teeth on regular 3/8.Thanks Chris. I've seen some of it referred to as .365 rather than .375, and the bar sprocket noses are slightly different also.
Is it just a Stihl Picco thing or will all 3/8 noses be fine with low profile chain? Perhaps it's not the pitch as such but the shape of the sprocket teeth?
Would a 3/8 rim work for 3/8 low profile chain? If not then is the pitch really 3/8 or less?
If I order a 100 ft roll of .375 chain, then, and it is only .366 do they still owe me a couple feet or did I get a few free cutters? Dang free stuff.
