An Adjustable Spanner Wrench supports adjustment and service activity within air conditioning systems by allowing controlled rotation of fasteners with differing dimensions. A variable jaw opening enables the wrench to engage multiple fastener sizes without interruption, supporting workflow continuity during service steps. Rotational input applied through the handle transfers turning motion to the fastener, allowing tightening or loosening actions to be carried out gradually. It controlled movement supports alignment of connected air conditioning components during fitting or release actions. Attributes:• Allows adjustable jaw opening for fastener engagement.• Supports controlled rotation of air conditioning fasteners.• Transfers hand input into a turning motion.Applications: An Adjustable Spanner Wrench is used in air conditioning service activities to apply controlled turning actions on fasteners during installation, adjustment, and removal tasks.
