Micro Screw Torque Standard Guide M1.0-M2.0 Electronic Assembly Torque Specification
Micro Screw Tightening Torque Standard Guide M1.0-M2.0
Micro screws are widely used in precision electronic products. Accurate tightening torque is essential to avoid thread slipping, head cracking and loose connection.
Micro Screw Torque Comparison Table
| Size | Carbon Steel Torque (N·cm) | Stainless Steel Torque (N·cm) | Application |
| M1.0 | 2.0 – 3.5 | 2.5 – 4.0 | Micro sensors, watch parts |
| M1.2 | 3.0 – 5.0 | 3.5 – 6.0 | Earphones, lens modules |
| M1.4 | 4.5 – 7.0 | 5.0 – 8.0 | Mobile phone components |
| M1.6 | 6.0 – 9.0 | 7.0 – 10.0 | Tablets, small appliances |
| M2.0 | 8.0 – 12.0 | 9.0 – 14.0 | Wearable & medical devices |
Key Notes
Excessive torque causes screw damage, while insufficient torque leads to loosening. Stainless steel screws require slightly higher torque. Regular torque calibration is necessary for mass production to ensure assembly stability.
