Hi there. I encountered this weird screw drive I have personally never seen before. Unlike a tri wing which is a recessed screw drive, this is a boss? Seems proprietary. On the off chance it isn’t, has anyone encountered this before and/or know what it’s called? Thanks.
These are called “Y” slot screw heads. They are sometimes used for anti-theft nut also where they do not want people servicing the device.
