This double ended socket is just the ticket for A4 (Mk4) chassis Golf/Jetta/New Beetles because the front struts have BOTH sizes to remove. Some earlier models (A3 chassis) that have VR6-type strut bushings also require both sizes. The 8.5" long heat treated box wrench holds the socket using snap rings. Interior has a thru bore that allows you to reach inside and hold the strut shaft with a standard 6 or 7 mm hex bit (3/8" drive). Some brands of strut use 6 mm and some use 7 mm hex - sold separately. The square hole in the handle permits the use of a torque wrench to set the nut torque to factory specs.
Improved - torque wrench compatible! Heat treated alloy steel. Not for impact tool usage.
