Description
Tightening screws on sensitive components must not exceed a defined torque. The 4-970-A bit set provides two preset torque adapters at 0.1 and 0.2 Nm plus a 42 piece C4 bit set, all packed in an impact-resistant plastic case.
Benefits
- Two torque adapters at 0.1 and 0.2 Nm, tolerance +/-10%, protect miniature screws from overtightening.
- 42 C4 bits in slotted, cross-recess, Torx, hex, and other profiles cover almost every miniature screw.
- Dissipative ESD bit holder at 10^6 to 10^9 ohm enables use at ESD workstations.
- No torque release when loosening, giving up to 30% higher breakaway torque without extra tools.
- Plastic case with foam insert, 175 x 160 x 45 mm, 410 g, keeps all 47 pieces organized.
Application
- Repair and maintenance of smartphones, tablets, and electronics with miniature screws.
