How are electric screwdrivers tested before shipment?

Electric screwdrivers should be tested before shipment for appearance, function, torque, speed, runout, battery performance, motor and gearbox condition, accessories, and packaging.

We recommend checking:

Appearance: scratches, dents, color, logo, coating, and assembly quality

Forward/reverse operation: confirm both directions work correctly

Torque: verify each torque level and check repeatability

Automatic stop: confirm the screwdriver stops correctly at the designed torque condition

Speed: check RPM and speed stability

Runout: inspect for excessive bit or shaft wobble

Motor: check noise, vibration, current, temperature rise, and operating stability

Gearbox: check backlash, abnormal noise, slipping, and smooth transmission

Battery: voltage, charging, runtime, battery model, and protection functions

USB-C charging: confirm connector fit, charging current, cable, and charging indicator

Buttons, display, and LED: verify all controls and indicators

Bits: check quantity, type, material, hardness, tip accuracy, and magnetic performance

Aging test: confirm performance remains stable after repeated operation

Accessories: verify cables, extension shafts, manuals, and other included parts

Packaging: check case, inserts, labels, barcode, retail box, and outer carton

Quantity: confirm total units, cartons, accessories, and spare parts

For ToolQeen multi-stage precision electric screwdrivers, torque testing should include 0.05, 0.15, 0.25, and 0.35 N·m, together with automatic-stop, runout, battery, and post-aging checks.

For OEM orders, the finished goods should be compared with the approved golden sample, final specification, BOM, packaging artwork, and QC standard before shipment approval.
