why use torx bolts?

macafee2 · 13th August 2017, 14:42

If there is sufficient space to fit a standard bolt head and get a socket it,
what is the reason for using a torx bolt?
In the early days perhaps it was so only manufactures could work on car, I don't know but with so many tools available, what's the point?

I'm tempted to replace the two torx bolts, that hold the offside drive shaft support with standard headed bolts. Any reason not to?

Provided you use fastenings the same tensile strength .No .However ,if an accident occurred Insurers could argue against suitability.

I don't know what the engineering reason is for it, but on my Megane a lot of the torx fasteners also have a hex head simultaneously. Nice touch.

Torx are certainly preferable to Pozidriv though.

Faster and more reliable on a production line?

They're much easier to put in with automated machines on production lines. Unlike Pozi-drive fasteners, they're designed not to make the driver slip out at the torque increases.

I wondered if this counted as a mod
