Torx screws are screwing me over

The difference between Torx and Torx Plus is that the Plus is a different shape. regular Torx sockets are a hexobular shape with a 15º pressure angle. Torx Plus is more like a spline drive with a 0º pressure angle.

See if you can post a close-up photo of an undamaged one. What size Torx wrench are you using, and have to tried the "next size up"? If it's a regular Torx shape such as T10, get a Wiha or Bondhus tool. If you think it may be T0IP (Torx Plus), try getting a T10IP wrench and test the fit.

I think you're right. Most Torx screws for inserts are different, although you can get away with using a standard driver if you are careful, at least I've been able to. Using the wrong size, easier than you may think in the smaller sizes, or using power tools will produce the results pictured. I only buy named brands normally like Wiha or Wera and I've had not problems.
