This means that the distance from the center of the square drive of the mating torque wrench to the center of the fasteners is exactly 2".

This one will NOT work. **Q: Doe anyone know if the 1/2" socket is "sloppy" (oversize: 0.512" ) enough to fit a 13mm nut?** A: Most 12 point wrenches have some "play" in them but I would recommend getting the 13mm torque adapter instead. **Q: i already have the 1/2" and 3/8" size of this torque adapter. How can I purchase the 1/4" size? is there a part#?** A: I don't think anyone makes a 3/8 drive 1/4" torque adapter. Best bet is a 1/4" wrench because the torque on a fastener that size will be minimal. Light pressure on the wrench will do the trick ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic little wrench . *by K***R on July 30, 2025* This works fantastic on the tight places on my Harley.
