Genius Tools Triple Square Bit Sockets 3/8" Dr.
Triple square fasteners, with their 12-point recess, are used on drivetrain, suspension and interior parts of many vehicles. These Genius Tools Triple Square Bit Sockets fit that recess and drive it from a 3/8" ratchet or torque tool.
The series covers M4, M5, M6, M8, M10, M12 and M14. Each size is offered in 50mm, 110mm, 140mm, 180mm and 220mm overall lengths. The longer bodies are useful for axle, seat and gearbox fasteners that sit inside deep openings.
All sockets are made of High Speed Tool Steel. A hard, correctly sized tip seats fully, so you can apply full force without rounding the 12 points. The catalog page also offers the BS-307M (50mm) and BS-307ML (110mm) 7 piece sets.
Mechanics working on vehicles that use triple square fasteners will find the 3/8" drive range covers most everyday jobs. Using the correct triple square tool instead of a star or hex bit is the best way to avoid damaging these fasteners.
