Our Insider box ratchet 6-point sockets are designed to uniquely fit into our M12 Fuel Insider box ratchet to deliver unrivaled access. The low profile design allows access in the tightest spaces and delivers pass-through capability up to 15 mm and 9/16 in laser etched markings on both sides of the socket allow for greater visibility to change between drive sizes quickly. A dual retention groove system allows for the Insider box ratchet 6-point sockets to be inserted into both sides of the tool for greater accessibility. These 6-point sockets have optimized geometry to reduce bolt rounding and stripping. We back all our sockets with a lifetime guarantee.
