Tri Groove nuts are a type of security nut that feature a tapered diameter, making the nuts resistant to gripping devices. They can only be removed with their special tri-groove socket drivers, which grip the indentations along the outside of the fastener to turn the nut along a thread."

them resistant to gripping devices. They require a special Tri
Groove socket for installation, as the socket grips the indentations
on the outside of the fastener and turns the nut along a thread."
