Universal Screw

The U2 Universal screw is extremely versatile. Although it looks like a drywall screw; that is where the similarity ends. It takes high quality carbon steel to properly case harden a screw. U2’s standards require case hardened screws so that there is no head strip out and even the 12” screw will not break during insertion. The exterior coating has been tested and certified to be used in the most toxic pressure treated lumber. Even at grade the Universal screw will not rust or corrode. Other engineering features insure quick starts even in hardwood. The bottom threads are configured so that they cut through the wood grain so that splitting due to grain separation is minimized and the cutting pockets under the head create a clean uniform hole during countersinking. On screws longer than 2” the reversed threads above the insertion threads are designed to minimize torque on the screw and reduce the tendency of wood to ride up the shank.
