You have been very lucky. I am not prepared to take that risk.

Odd. I've taken plenty of Thinkjets (and 9114 drives, which use the same 
screws) apart and had no problem getting tools that fit. IIRC, though, HP 
used some odd-size screws in these machines, with TX9 heads. Some 
manufactuers make their Torx drives on the small side, so you may have 
found a TX10 from said manufactuer fitted, but 'real' TX10 drivers don't. 
A good TX9 driver will work, though.
