The Tri-Wing is a type of screw and screw head. It is sometimes called a triangular slotted screw. It is used as a tamper-resistant screw on various products, typically electronics. The Tri-Wing is a tamper-resistant screw due to the rarity of Tri-Wing screwdrivers in hardware stores, although they can be legally bought online.
