 | XT Extra Torque Woodworking Screws Extra Torque (XT) means just that! Commonly found “wood” screws will actually break around 25-30 inch/lbs. While that may be fine for drywall or other light duty applications, woodworking demands something better. |  | The Square Drive Advantage Bits are less likely to jump out of the recess and allows for more driving torque. Square Drive offers a positive stick-fit which stays on the screwdriver bit tip; handy for starting screws overhead or from other difficult angles. Bits will last longer and are less likely to damage the screw. |  |
