• Openings are of the same size
• Use the slotted opening generally for quick run down
• Use the box end for final tightening and/or to avoid obstructions
• All 12 point box openings through 2 in fractional size are "Lobular" design which reduces the risk of fastener rounding, provides a better grip on worn fasteners and allows more torque to be applied to the fastener
