The BGS Technic 5170 is a professional 20-piece bit socket set designed for automotive repair, mechanical maintenance and workshop applications. The set uses a 12.5 mm (1/2") square drive and includes three commonly used fastening profiles: internal hexagon (HEX), T-Star/Torx and XZN spline.
Each bit socket is approximately 100 mm long and features a ball-head working profile. This design allows the tool to be positioned at an angle when access is restricted, making the set particularly useful in difficult-to-reach areas.
The set contains 7 HEX sizes, 8 Torx sizes and 5 XZN sizes, covering a useful range for professional automotive and mechanical work. The bits are manufactured from S2 steel, providing a suitable material specification for professional hand-tool applications.
