A pocket screwdriver which comprises: a hollow shaft having first and second ends; said first end having an interior surface contoured for engagement with a known length of a hexagonal shaft of a tool bit; a magnet attached to the interior of the hollow shaft at a point along the longitduinal axis of said shaft for magnetic attachment to the end of the known length of a tool bit\s hexagonal shaft, said magnet being used for receiving thrust imparted through the tool bit to said hollow shaft and for magnetically holding the hexagonal shaft of a tool bit in said first end; said magnet further defining an upper compartment within said hollow shaft, said compartment further being sized for receiving a tool bit for storage therein, and said compartment being accessible through said second end; said shaft further having a radially penetrating hole disposed at a point along the longitudinal axis between said magnet and said second end; a plurality of paramagnetic tool bits each having a hexagonal shaft of known length for engagement with said first end and said magnet; a torque cap having a first segment having an outside dimension sized for insertion into said radially penetrating hole, a second segment coaxially attached to and aligned with said first segment, said second segment having an outside dimension for insertion into said second end, and a third segment coaxially aligned with said second segment, said third segment having an outside dimension larger than that of said second segment; and means for retaining said torque cap in said second end or said radially penetrating hole.
