Usage Scenarios
Bolt Tightening: Suitable for tasks such as mechanical repairs, automotive maintenance (e.g., tightening or loosening car bolts), and household projects like securing screws when assembling metal racks.
Steel Pipe Connections: Ideal for connecting steel pipes using fastening components. The impact wrench ensures bolts are tightened more securely compared to manual tools.
Unrecommended Conditions
Precision Assembly: The high torque and impact force may damage delicate components or cause over-tightening, affecting equipment performance.
Soft or Brittle Materials: Using the tool on materials like aluminum, plastic, or ceramics may lead to deformation or breakage.
Small Fasteners: Small bolts or screws may not withstand the high torque and could be stripped or broken.
High-Precision Torque Requirements: Applications that require precise torque control may experience under- or over-tightening.
Vibration-Sensitive Environments: The impact force may increase vibration, affecting stability or causing components to loosen.
Confined Spaces: Limited working space may hinder tool operation and increase the risk of damaging surrounding parts.
Frequent Assembly/Disassembly: Regular use may accelerate thread wear and shorten the lifespan of fasteners.
High-Speed Applications: Not suitable for continuous high-speed use, which may cause overheating or damage to the tool.
