Am I wrong?

Is it me, or torch head bolts needs to be double deep?No matter the care I take. They always ends like that in my first try.

 

You're referring to Torx head bolts I see. You typed "Torch" unless you were using voice typing or auto correct.

Anyways it always seems as if they don't make them deep enough IMHO as well.

A lot of Torx bit set skip sizes, this okay a lot of the time but for jobs where the bolt is really tight or it has exposed threads such as on seat runners the bit needs to be a really snug fit.

I always try to go up one size even if i'm fairy sure I have the correct size. It is quite often the next size up that is required in my experience.

Found this out dropping the driveshaft on the 2010 Ford Escape. It was a first time on one of these cars for me, not a Ford guy. Used Allen Head and found out I almost ruined one bolt head .

Luckily I found the correct bit type & size by looking more closely at the bolt head after it first slipped. Once I got the correct size dialed in I used a hammer lightly tapping the bit in till it fit back properly in the bolt head. 

After I got it in the bolt head and all but the last bolt removed it was able to remove it for me and saved the Torx bit in the bolt. 

 

Quick tip:

If the torx head is already in a bad shape and the bit doesn´t have the right "grip" anymore you may want to fill the head with valve grinding compound and stuff the bit into it. That way many damaged bolts still can be retracted easily. Actually this evolved from the phillips screw technique.
