Fits well on th castle nut, and us 3/4 drive compatible. It is also made well with an anodized finish. This tool is small fits well anywhere. Great quality and this tool from Spikes Tactical works great. Just what you’d expect.

Spikes castle nut wrench is great. It has very sharp and crisp notches to engage the castle nut. There is no more slipping and boogering up the castle nut with this tool. Very heavy and well machined. I just wish I would have bought one sooner.
