3. QUADREX® DRIVE
QUADREX® IS A LICENSED RECESS, ORIGINALLY DEVELOPED IN CANADA. AS A DRAMATIC IMPROVEMENT OVER A PHILLIPS RECESS, IT PROVIDES MULTI-POINT CONTACT WITH THE DRIVER BIT AND INCORPORATES FOUR PERPENDICULAR CONTACTS. THE BENEFIT IS A DRIVER-RECESS COMBINATION WITHOUT THE CAM-OUT ACTION OF A PHILLIPS. SCREWS CAN BE DRIVEN AT SEVERE ANGLES AND STILL MAINTAIN CONTACT OF DRIVER AND RECESS. ADDITIONALLY THE LIFE OF DRIVER BITS IS PROLONGED, RECESSES ARE NOT STRIPPED OUT, AND THE COATING WITHIN THE RECESS IS NOT ABRADED TO THE EXTENT OF A PHILLIPS DRIVE.
