Facom 1/2" Drive Grip Bit Socket - for the safe and effective removal and installation of hex bolts and screws, including ones that have been damaged. These sockets were engineered by Facom in France and are also available through Mac Tools (a sister company to Facom, both part of the Stanley Group) as their RBRT™ sockets (Rounded Bolt Removal Technology). No need to buy a whole set if you're only using 1-3 sizes. Sets are available in small plastic cases by drive size.

Try to avoid using drive accessories (universal joints, drive adapters and extensions) when applying torque to the fastener. See video for further details.
