Tri-Wing®
The tri-wing, also known as triangular slotted, is a screw with three slotted “wings” and a small triangular hole in the center. Unlike the “tri-point” fastener, the slots are offset, and do not intersect the center of the fastener. A version with left-hand threads is called an Opsit screw, where unscrewing can be done by turning the screwdriver clockwise, which is the opposite of tri-wing and regular screws.
