What are the torx screwdriver sizes?
What is the difference between a T9 and a TR9 screwdriver? Thanks.
Is this a good question?
MrMightyReedy, TR9 is a Torx security screwdriver. It will have a hole in the center which the regular T9 does not have. this is to accomodate the center post inside the Torx security screwhead
