STA360 is a professional aviation maintenance tool compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft mechanical and hydraulic system maintenance.It acts as a high-precision torque wrench adapter, paired with torque wrenches for precise fastening of bolts and nuts in critical components like engine casings, landing gear struts and hydraulic pipeline joints during MRO. It ensures accurate torque transmission, avoids over-tightening or under-tightening, prevents fastener fatigue, thread damage and component loosening under extreme vibration, securing structural integrity of key parts.Made of high-strength alloy steel with heat treatment, it resists wear and deformation, works stably at -55℃ to 200℃. Weighing 0.35kg, it features universal compatibility and easy operation, with precise dimensional tolerance for reliable torque control. It’s a critical auxiliary tool to guarantee standardized maintenance and aircraft flight safety.
