The Sparta 1/2" Air Impact Wrench (Model: SP-407W HD) is a heavy-duty pneumatic impact wrench designed for automotive workshops and industrial applications that require high torque outputs. 
Product Specifications
Drive Size: 1/2 inch square drive.
Maximum Torque: 1,560 Nm (Newton-meters).
Power Source: Pneumatic / Compressed Air.
Key Applications & Usage Guidelines
Heavy-Duty Tasks: With a maximum torque capacity of 1,560 Nm, this tool provides the extensive power needed to break free rusted, stubborn, or highly torqued nuts, such as those found on heavy vehicle wheels and suspension setups.
Socket Safety Requirements: Because of the sudden and powerful kinetic force this impact wrench delivers, it must exclusively be paired with specially hardened, six-point impact sockets, extensions, and joints. Standard chrome hand-tool sockets can shatter under this amount of load
Final Tightening Caution: Pneumatic tools with high torque should not be relied upon for the precise, final tightening of critical assemblies like wheel lug nuts. Final tightening should always be verified manually using a calibrated manual torque wrench to avoid over-stretching or shearing the wheel studs.
