Torque wrench

Do you really need the 3/8 if you have the other two?

Although unless you're building a lot of modern engines(cam caps, weak plastic valve covers etc), there isn't a lot of use for a 1/4" torque wrench on a car either.

I’d reiterate what nick says. Proably 90% of mechanics go their entire working lifetime without a 1/4” or 3/8” one.

You’d be better off buying two half inch ones, a shorter less cumbersome low range and a high range. Short one for general stuff like rods, cam caps etc. and the big one for hub nuts and flywheel nuts.

If you do want a 1/4” one, generally for electrical work, get a torque screwdriver instead, they’re much more useful.

Cheers, thanks to all
