1/2" Drive Adapter/Coupler - 1/2" to 3/8" (S.230) - Chrome finish. Overall height = 33.5mm. Maximum torque = 212nm (approx 150 ft lbs). The S.230 adapter or the 3/8" drive socket will likely fail if you try to use these with a 1/2" drive breaker bar to remove stubborn wheel bolts. Please upsize to 1/2" drive for any torque applications over 100 ft lbs.
