Simpson Strong-Tie Quik Drive 3-Piece 1-in T25 Torx Steel Hex Shank Screwdriver Bit

It is necessary to use the right driver bit to ensure optimum results with a Quik Drive system. The bit(s) included in each box of Quik Drive screws should be sufficient to drive the entire box, however variations in materials and driving techniques can shorten driver-bit life. Replacement bits are available in Bit Packs; reference the label on the bit included in the box or the box label to ensure correct replacement driver-bit selection.
