I noticed when I got some Pinhead Wheel Locks that they came with an extra funky looking washer that looks like this:
They didn't describe much about it, but I did find some information about them:
- It seems like without the washer you can use a Gator Grip Socket to unlock them.
- Pinhead responded to this discovery by creating these washers and making this video. But in the video they didn't describe how exactly they work to thwart the Gator Grip attack.
- They give them for free on their website to people who don't already have them.
