Wiha PicoFinish 3/16" x 160mm Hex Nut Driver

Wiha PicoFinish® precision nut drivers are built for fine hex-nut and standoff work in electronics, instrumentation, and communications equipment. The hollow hex barrel engages nuts and standoffs cleanly without slipping. The dual-durometer handle gives palm-roll speed and torque-sensing feedback for controlled fastening on small hardware.

Where this tool is used

• Electronics assembly — PCB standoffs, terminal nuts, and connector locknuts in M2–M5 sizes are standard in panel and rack-mount equipment.
• Instrument and process analyser maintenance — hex nuts on terminal blocks, sensor housings, and cable glands require precise torque to avoid overtightening.
• Telecommunications and data-centre work — patch-panel and rack-mount hardware uses imperial and metric hex nuts for equipment mounting.

Key specifications

Selecting the right option

Match the hex size precisely — a loose fit will round the nut. For ESD-sensitive assemblies, select the ESD variant. PicoFinish® nut drivers are sized for hand-torque precision work; for higher torque requirements, the SoftFinish® nut driver range provides larger handles and longer reach.
