For applications where screws and bolts must be torque-tight and tamper resistant.The tri-wing, also known as triangular slotted, is a screw with three slotted 'wings'and a small triangular hole in the centre.
The design was adopted by some partsof the aerospace industry, led by Lockheed in the early 1970s. In the present dayit is usually seen on electronics equipment.

Based on the Standard Bit, the other bits are optimized by means of various hardening and coating methods. It provides a consistent hardness of ~700HV and features a highly accurate fit in the screw.
The Classic Hexagon Ball End Bit is hardened using a special procedure. The tough version resulting from this method meets the demands across all areas of industry and craft.
