JM-8146 47-in-1 Precision Screwdriver Set, CR-V Steel

JM-8146 Precision Toolset

The JM-8146 Precision Screwdriver set provides a comprehensive solution for technical professionals requiring high-accuracy torque application on sensitive electronic components. This 47-in-1 hardware kit utilizes Chrome Vanadium (CR-V) steel construction to ensure structural integrity during high-repetition maintenance tasks. The architecture of the driver handle incorporates a non-slip ergonomic grip with a 360-degree rotatable cap.

Key Features

• Industrial Grade CR-V Bits
  Each bit undergoes high-temperature quenching to achieve a hardness rating of HRC 50-52 for extended service life.

• Extended Reach Capabilities

  • Includes a 130mm H4 extension bar for accessing recessed fasteners in deep chassis.
  • Features a 100mm multi-angle soft extension bar for navigating obstructed internal layouts.

• Magnetic Bit Retention
  The internal socket utilizes a strong permanent magnet to secure bits and prevent fastener loss during vertical operations.

• Comprehensive Bit Geometry

  • Torx: T3, T4, T5, T6, T7, T8, T9, T10, T15, T20
  • Hex: H1.3, H1.5, H2.0, H2.5, H3.0, H4.0
  • Phillips: 1.0, 1.5, 2.0, 2.5, 3.5
