tamperproof bits for non-tamperproof applications

[scottmlew]

Other than some loss of strength, is there any reason to not use tamperproof Torx or Torx Plus bits for non-tamperproof applications? Aren't the "drive surfaces" the same?

[rjspitz]

Yes, the external dimensions are the same and will work. But as you stated, there will be a loss of strength and the bit may collapse at higher torque.

I bought tamperproofs from T15 to T30 thinking they'll be adequate to handle non-tamperproof torx fasteners.

I bet you get rust up there. I would NOT use them on brakes. I have both Snap-on and Craftsman and have had to use both to remove rusty brake torx (sometimes rust/gunk fills the head and the softer Craftsman work better, other times the stiffer Snap-on works better).

Anybody else have area's they wouldn't use them on?

Sure, they work fine if you don't need much torque. Don't expect even a good tamperproof to stand up to a goodly amount of torque, though. I got so mad at myself for twisting one like a candy cane because I was too much in a hurry to walk over and get the non tamper proof bits.

Really? Wow. I wouldn't have thought they'd be THAT much weaker.

So now my question is -- are tamperproof versions used only in low torque applications, or does the little "peg" in the middle provide that much extra strength (by preventing the hole in the middle of the bit from compressing/deforming)?

Well, I was removing some rusted screws with my Dewalt impact driver. It was a good USA (Lisle, I think) bit, and it twisted like a candy cane. Obviously, it was not impact rated.

Are the tamperproof even that common. I have a set, and have used it on the non, but about the only application I can remember using one on was an Allen-Bradley safety pull cord switch.

[rjspitz]

Yeah, the peg should act similar to how a mandrel bender works. Then again, security screws aren't usually used in high-torque applications.

how about TORX PLUS !!!???
