Facom 1/2" Drive Long-reach Hex (allen) socket - 8mm (ST.8L) .......Very stable (non-removable) bit. Recommended for higher torque applications. Overall length = 4" (100mm). 1 left in stock. Made in France.
Note - this is the same as the SHP.8LA although I only stock the USAG version of the replacement because it is identical at a much lower cost and has a US warranty).
