A: 1/2” size or 1/2” drive?

**Q: Is there a 1/2" version?**
A: per the PROTO website, they are only manufactured in 1/2" drive

**Q: What is the width of the wrench 9/16 end. I have a shovelhead cylinder bolts to tighten and sockets wont fit, too tight between fins?**
A: This works great on my 78 FXS Shovelhead Lowrider.

**Q: Would it be possible to purchase a (3/8 drive torque adapter 1/4-inch) without having to buy the entire torque adapter set?**
A: Probably. I purchased the single 3/8’s drive x9/16 one. So I would imagine you could fine that one without purchasing the entire kit.
