Complete Set: The 3D carpenter square set includes a red carpenter's square, a dowel, a wrench, two screws, and two carpenter's pens. The carpenter's square can measure lengths and angles, draw holes of varying sizes, and draw long straight lines at varying distances from an edge, making it a highly practical tool for precise data requirements across a wide range of tasks High Precision: The 3D carpenter square features six angle pin holes (with dowels) and a precisely calibrated scale. The hole position scale is pre-set at 22.5°, 30°, 45°, 60°, 67.5°, 75°and 90°, with millimeter-level graduations, allowing for seamless angle measurement and marking. Whether marking lines, measuring lengths, or determining angles, the carpenter's square ensures precise measurements Detachable Design: The 3D carpenter square's detachable design ensures ease of use. Simply tighten the two included screws with the provided small wrench to create a 3D multi-angle measuring tool. When not in use, you can remove the screws to convert the carpenter's square back into an angle square and set square, making it easy to store in your tool bag and carry with you High Quality: The 3D carpenter square is made of high-quality materials that are lightweight, strong, and durable, resisting paint peeling and ensuring long-term use. Compared to traditional wooden or plastic rulers, the 8mm thickened blade is more durable and maintains accuracy over time without warping or damage Wide Applications: The 3D carpenter square's ergonomic design makes it widely used not only in carpentry, but also in construction, renovation, furniture manufacturing, and more. Ideal for measuring, marking, and checking angles, it's an essential tool for professional carpenters, DIY enthusiasts, and window and door installers, Manufacturer: HOVCEH
