Shimano RD-M8000-GS adjustment screws

The adjustment screws/bolts of the Shimano RD-M8000-GS (11-speed Deore XT) rear derailleur:

H (High speed) - smallest cog/sprocket side limiter

L (Low speed) - largest cog/sprocket side limiter

B (B-tension) - so-called "end" screw/bolt

The hex size is 2mm.

Be careful not to confuse the B screw/bolt with the H screw/bolt. This rear derailleur has an unusual placement of them.
