The Beta 99ST 80-120 is a comprehensive set of hook spanners with swivel hooks and pins, designed for professional and workshop applications requiring precise torque application in hard-to-reach areas. This hand tool set features 11 individual spanners covering a range from 80 mm to 120 mm, with each tool constructed from high-grade chromium-vanadium steel for exceptional durability and resistance to deformation under load. The innovative swivel hook design allows for secure engagement with fasteners at various angles, while the integrated pins provide additional stability during operation, reducing the risk of slippage and potential damage to components. Each spanner in the set has been precision-machined to ensure accurate fitment and consistent performance across the entire size range. The tools feature a matte black oxide finish that provides corrosion resistance and reduces glare in workshop environments. The ergonomic handles are designed with user comfort in mind, featuring a textured grip surface that enhances control during extended use. This set is particularly suitable for maintenance, repair, and assembly tasks in automotive, industrial, and mechanical applications where standard wrenches cannot be effectively utilized. The compact and organized storage case included with the set ensures all tools remain protected and easily accessible. All measurements are provided in metric units, with spanner sizes clearly marked for quick identification. The Beta 99ST series represents a successor model to previous hook spanner designs, incorporating improvements in material quality and functional design based on professional user feedback.
