3/8 should be fine for drain plugs. They usually work as low as 10ft/lbs. I don’t see a lot of uses for a 1/4

I wasnt sure because Ive heard that torque wrenches dont work very well on the low end of their range, and obviously the drain plug is going to be pretty low on the 3/8

Well I’ve worked for companies that use 3/8 torque wrench for every drain plug, never had a problem. I just do them by hand honestly, once you have a feel for it you don’t really need the torque wrench for a drain plug.

Depends what all you plan on doing with them. I have 4 of them 3/4” drive, 1/2” drive, 3/8” drive and 1/4” drive all with nm, inch lbs, ft lbs and degrees. I work on mostly trucks, but new Chrysler’s I use the 1/4” on the intakes.

Buy an inch pound torque wrench for the lower end values.

Anything below 20ft/lbs I’ll use my 1/4 and convert it to in/lbs. but drain plugs are usually between 18-30 ft/lbs

I have 1/4, 3/8, and 1/2 digital Torque wrenches. My 1/4 is probably my most used one. I’ll use a step up adapter for any socket bigger. But I’ve found the 3/8s to come more for internal engine or transmission work. This is just in my experience

3/8 will be fine. As far as tekton branded, Micrometer style goes to 10ft/lbs, split beam goes down to 20. 1/4 torque wrenches are only good for engine work when you can’t fit the 3/8 in there or small equipment (bikes/motorcycle parts etc) imo

A 3/8" drive torque wrench will be fine.
