Still cuss every time I work on something metric or with torx or with tamper proof torx. Or external torx.
Know how many thousands I've spent on fractional sae tools that I can no longer use?
Or worse yet vehicle with both sae and metric...
I came up on sae and I could look at a fastener across the shop and know which wrench or socket to grab....
And I work on cars and trucks daily for a living.
I just pulled the trans out of my Durango this morning. Everything that attached to that 360 was sae as it SHOULD be . Everything that attached to the body and frame was freaking metric. Even the driveshaft bolts were freaking metric. Id like to meet whoever came up with that idea and hang them by their private parts...
