接線柱扳手

Finally, a tool that actually fits binding posts without slipping. The hex-shaped handle gives great leverage for snug tightening without stripping.

The knurled handle gives way better grip than the tiny stamped wrench I was using before, so tightening the collars on my speaker terminals doesn't slip anymore. Small thing, but it lives in my cable bag now.

The wrench fits binding posts snugly without slipping, which makes tightening them way less fiddly than using pliers. I've used it on both my amp and speakers and the grip stays solid every time.
