HT2 has been out for almost 20 years now and the tool for the crank pre-load hasn't changed since it was introduced, could understand an issue if Shimano changed the spec every few years, but they haven't, the only change in HT2 since it's introduction has been the size of higher end bottom brackets (smaller shell size), and when these changed (not bought one recently, so unsure if they still do) the retail packaged BB's came with an adaptor to if the older tools.
As you need a tool to fit the BB's as
alcjphil notes, the Park BBT9 is an all in one which includes the BB and crank tool.
