1/2-Inch Drive Adjustable Torque Wrench 20-330Nm Chrome Finish
1/2-Inch Drive Adjustable Torque Wrench 20-330Nm Chrome Finish
This industrial-grade adjustable torque wrench delivers precise fastening with an accuracy of ±3%, meeting ISO 6789, ASME B107.14, and GB/T 15729 standards. The durable alloy steel body features a chrome-plated finish for corrosion resistance, while the ratchet head with a reversing switch enhances efficiency in tight spaces.
A clear double-reminder system—a tactile impulse and an audible click—signals when the set torque value is reached, preventing over-tightening. Each wrench includes a unique serial number for traceability, and the front replacement rod design allows for convenient storage.
