The Screwdriver Torque Testing Machine is primarily designed to evaluate the torque performance of screwdrivers. The test specimen is securely installed between adjustable fixtures, allowing the machine to measure the screwdriver's torque, maximum torque, and qualified torque.
The machine adopts computer-controlled operation and can acquire and analyze various test parameters, including torque, peak torque, torsion angle, and test curves.
The Screwdriver Torsion Testing Machine can be used for testing and evaluating screwdrivers and related fastening tools according to the following standards:
GB/T 10639-1989 — Slotted Screwdrivers
GB/T 10640-1989 — Cross-Recess Screwdrivers
GB/T 3229-2018 — Assembly Tools for Bolts and Nuts — Dimensions and Torque Test of Driving Ends and Connecting Parts of Hand- and Machine-Operated Screwdriver Bits (Modified adoption of ISO 1173:2001)
GB/T 10635-2013 — General Technical Requirements for Screwdrivers
GB/T 10128 — Metallic Materials — Torsion Test Method at Room Temperature
GB/T 2611 — General Technical Requirements for Testing Machines
JJG 269 — Verification Regulation for Torsion Testing Machines

Torque Measurement: Measures the applied torque of the screwdriver.
Maximum Torque Measurement: Determines the maximum torque sustained by the test specimen.
Qualified Torque Evaluation: Evaluates whether the measured torque meets the specified requirements.
Peak Torque Detection: Records the peak torque during testing.
Torsion Angle Measurement: Measures the torsion angle of the specimen.
Curve Analysis: Displays and records:
Torque–Time Curve
Torsion Angle–Time Curve
Torque–Torsion Angle Curve
Data Management: Supports test data storage, retrieval, and printing of test reports.
The equipment is suitable for screwdriver manufacturers, hand-tool manufacturers, quality inspection laboratories, and R&D departments for screwdriver torque performance testing and quality control.
