Precision and Watchmaker Screwdrivers
Screwdrivers and Bits
Precision and watchmaker screwdrivers work below 3.5 mm blade width, where the decisive factor is not torque but keeping the blade aligned. Their characteristic feature is the rotating cap at the end of the handle: the thumb holds the axis and the contact pressure while index and middle finger turn the slim handle, so the blade stays perpendicular in the screw head. The range covers slotted blades from 0.8 to 3.5 mm, Phillips PH0000 to PH1, Pentalobe PL1 to PL5 and fine TORX sizes, partly with aluminium handles, partly as magazine or cassette sets. The category holds 162 items, the leading brands are Wiha, Bernstein and Lindström.
| Profile | Sizes | Blade length |
|---|---|---|
| Slotted | 0.8 to 3.5 mm | 14 to 100 mm |
| Phillips | PH0000 to PH1 | 22 to 60 mm |
| Pentalobe | PL1 to PL5 | 40 mm |
| TORX | fine sizes from T4 | 40 to 60 mm |
Typical applications: Repair of smartphones, tablets and notebooks; watchmaking and precision mechanics with screws below 1.5 mm; adjustment of optics, sensors and measuring heads; work on connectors and terminal strips inside small enclosures; assembly and rework on printed circuit boards; service work on laboratory instruments with fine screws.
