Triangular head security bolts, also called triangular head security screws or security recess screws, are manufactured to DIN 22424 and consist of flange headed bolts with deep triangular heads.
Security screws feature special heads that make them both significantly harder to remove and more resistant to pressure or wear. Typically made from steel with a zinc coating, security screws are also known as tamper-proof, anti-tamper, and anti-theft screws.
Triangle screws are used for security reasons because they're difficult to remove without a TA screwdriver. Tri-wing screwdrivers are only compatible with a fastener head that has three slotted "wings" and a small triangular hole in the center.
