Long story short, I have to purchase a torque wrench which I will use to torque things like brake calipers, wheels and the like. To make things interesting, I will have to buy it a different size ratchet than all of the sockets I already own. I am therefore thinking of getting a ratchet adapter so that I can avoid purchasing more sockets and accessories.
Below is a picture of a 1/2" ratchet torque wrench next to a 1/2" to 3/8" step-down adapter as an example:
Does using a ratchet adaptor (say 1/2" to 3/8") on a wrench reduce the applied torque? How about using 2 adapters in series (say 1/2" to 3/8" to 1/4")?
