Wiha Screwdriver Picofinish Torx 9IP x 145mm - 278IP

Wiha PicoFinish® precision screwdrivers are engineered for fine electronic and instrument work requiring exact tip fit and minimal hand fatigue. The Torx Plus (IP) blade is manufactured in Germany from premium tool steel with a precision-machined tip that seats fully in the fastener recess, reducing cam-out on M1.5–M4 hardware. The dual-durometer handle combines a rigid hex finger-grip with a rotating top cap for rapid spin and a tapered body for palm-roll torque.

Where this tool is used

• Electronics assembly and PCB rework — fine M1.5–M3 Phillips and Pozidriv fasteners on circuit boards, connectors, and chassis sub-assemblies require a screwdriver that seats without rocking.
• Instrument calibration and repair in laboratory and process-control environments — actuator, transmitter, and analyser housings use small precision screws that must not be damaged during service.
• Telecommunications equipment installation and servicing — data-centre rack hardware, fibre-termination enclosures, and antenna assemblies all use M2–M4 fasteners.

Key specifications

Selecting the right option

PicoFinish® is the right choice for M1.5–M4 precision work. For ESD-sensitive assemblies, the ESD variant (IEC 61340-5-1) is required. Match the Torx Plus (IP) size exactly to the fastener recess — a loose-fitting tip causes fastener damage that can be costly in precision assemblies. For M4 and above, move to the SoftFinish® range for additional torque capability.
