Apex WSK Series Wobble Socket Adapter Kits can convert any fastener tool with a female square drive (3/8”, 1/2′, 5/8”, 3/4” or 1”) and a DIN groove into a Wobble socket. This will enable you to drive fasteners that may have a slight misalignment (up to 10°) between the drive tool axis and the fastener axis. In addition, this will also prove extremely useful in hand-drive operations where clearance may be an issue. The Apex WSK Series Wobble Socket Kit are available in 5 different square drive sizes.
