The DART Torx (TX) Impact Driver Bit range is the industry standard for tradespeople working with modern structural fixings. Unlike traditional cross-head bits, the Torx “star” design provides six points of contact, which virtually eliminates “cam-out” (the bit slipping out of the screw). This ensures 100% power transfer from your tool to the screw, preventing damage to the fixing and the surrounding timber. Each bit is manufactured from premium S2 grade steel, which is specially tempered to create a “torsion zone.” This allows the bit to flex under the intense peak torque of an impact driver, preventing the tip from shattering and significantly extending the tool’s lifespan. Whether you are installing decking, building retaining walls with railway sleepers, or fixing structural frames, these bits deliver the reliable, non-slip performance required for heavy-duty site work. Available Sizes & Specifications: We stock the most popular Torx sizes in both standard and extended lengths to suit a variety of construction projects: T20 (TX20): Available in 25mm and 50mm lengths.
