Hazet's Stub Allen Sockets are essential tools for any German Car mechanic. The short size and 1/2 drive allows application of high torque in tight clearance areas.Available in: 8, 10, 12, 14, 17, & 19mm.
The 10 mm size is seen in head bolts, flywheels and other high toque applications.
The 12mm 1/2 is just the ticket for drain plugs and the short height (aprox 30mm) helps in tight access conditions.
The 17mm has some new applications in Japanese as well as European cars.
The 19mm has many uses. Traditionally you need this socket for Mercedes fuel tank drains.
