Torque Wrench Digital vs Standard needs & review

Genes1s · 12-02-2020, 01:26 PM

Newer cars seems to have more stretch bolts everywhere and torque specs that requires additional angle.

For weekend/DIY er, what would be decent Digital Wrench brand that don't break my wallet and covers most of the stretch bolt torque specs for the suspension, engine, and tranny on 335i/135i ?

I'm looking at GearWrench and AC Delco specifically, as they seem to be the mid tiers. Anyone has good experience with Harbor Freight products? They look like very reasonably priced. Wish can afford Snap on, but it is out of my range.

I've read reviews and watch you tube alot on this topic, just want to get some info specifically from BMW folks.

Thanks

I bought a used snap on 3/8 digital tech angle torque wrench. 300 bucks. Can have it calibrated for 75 bucks, i personally didnt as im a cheap ass. Let someone else take the 600+ hit on it.

Take no offense here, but the only critical stretch bolts on a car are the cylinderhead bolts and big end cap bolts on the con rods and maybe some bolts on the timing gear system. The aluminum bolts on the N52 are used only on the engine block for things that bolt to it, to get a level of precision of bolt torque you are seeking with a digital torque wrench plus angle is far overkill IMO.

The only digital click-type torque wrench I have is a 1/2" drive, which I use for wheel bolts. I'm sure after 30-some plus years, it's not in calibration.

None taken. Appreciated the perspective, I thought about it too. Perhaps renting one that is fully calibrated when needed makes more sense...

I got a very good manual torque wrench from Tekton on Amazon.com. It is well made in Taiwan and calibrated from the factory. A few pounds off here and there are not a big deal. I have both 1/2 and 3/8 and I think its much better than relying on Harbor Freight. It does need to be stored properly to maintain its accuracy.
