Is the T6H, T7H, T8H, T9H, T10H -bit identical to the (torx security) TR6, TR7, TR8, TR9, TR10 -bit? And what is the reason for the difference in naming? I’m deciding whether to buy a precision screwdriver kit. T[…]H:
vs TR[…]:
The difference is the T6H is the torx security bit, and the T6 is the regular torx bit. I think you can use the torx security bit in the regular torx, but you definitely can’t use the standard torx driver in the security screw.
Hello, I just bought a set containing T6H and T8H bits and I can confirm they fit the TR6 and TR8 Torx Security Screws from the Mac Mini Late 2014 Hard Drive Replacement instructions. The T#H bits have a little divot in the center that accommodates the nib in the center of the security screws.Does the “R” in TR6 mean “Regular”? Or does the “R” designate that it’s a security screw? I have no idea and I wonder if some of the confusion on this thread stems from that “R”. Regardless, the T#H bits do work with security screws.
