USAG/Facom
1/2" Drive Extra Long-reach Hex (allen) socket - 6mm (USAG=234 series, same as Facom
SHP.6ELA2). Very stable (non-removable) bit. Recommended for
higher torque applications. Overall length = 8.7" (220mm).
Socket stocked is the USAG version as it is considerably less
expensive and has a US warranty. The Facom version can be special
ordered.
