Facom 1/2" Drive Long-reach
Hex (allen) socket - 6mm . Very stable (non-removable) bit.
Recommended for higher torque applications. Overall length =
4" (100mm).
Application Note - I use this
socket for most European axle shaft allen bolts (BMW, VW/Porsche,
etc). A fair amount of torque is required to break these bolts
loose.
