BC – tool selection

The BC app helps you identify fasteners, select the right tool based on drive type, and perform simple workshop calculations. It is useful for furniture assembly, minor repairs, working with bolted connections, and learning about tools. The library features illustrated articles explaining how to identify a fastener, its purpose, the appropriate tool to use, and key details to look out for. Search functions by name or text and category filters help you quickly find the information you need. Convert measurements in either direction using the precise ratio: 1 inch = 25.4 mm. The conversion formula is displayed alongside the result. Select a drive or head shape to identify the compatible screwdriver, bit, wrench, or socket type. Seven types are supported: flathead slotted, PH, PZ, hex internal, hexalobular star, square, and external hex. Input validation helps catch errors, and incomplete entries are saved so you can resume your work later. Keep fastener details, tools, and calculations at your fingertips with the BC app.
