Precision hex set for delicate fasteners

The Wiha Tools 26391 set contains eight SAE hex screwdrivers and nut drivers built for precision work on small fasteners. Each piece uses a round handle with black grips and chrome shafts fitted with black oxide tips. The range covers tip sizes from 1/16" to 7/64" and fastener sizes from 1/16" to 3/64". CVM formulated steel handles and satin chrome plating with Chrometop tips complete the specification.

Replaces mismatched mini drivers and loose bits

Technicians who currently reach for assorted jewellers' drivers or loose hex bits gain a single organised set that matches the full range of small SAE hex fasteners. The jump is worth it when a job repeatedly calls for sizes between 1/16" and 7/64" and a dedicated, colour-coded set reduces search time and cam-out risk.

Suits electronics, instrumentation

Engineers, hobbyists and field-service techs who work on circuit boards, small instruments or precision mechanisms will find the eight-piece SAE coverage convenient. Buyers who need metric hex, Torx or Phillips profiles, or who require larger shaft diameters for higher torque, should look at something else.

Questions about this item

What handle diameter and grip material does the 26391 set use for precision work?

The set uses round CVM-formulated steel handles with a black finish, designed to fit securely in the hand for delicate fastener tasks.

How are the hex shank drivers seated in the handle, and what common error should be avoided?

Each driver has a hex shank that locks into the handle; the error is not fully seating the shank, which can cause the tip to wobble under torque.

When should the black-oxide tips be replaced, and what wear signs indicate it?

Replace tips when the black oxide coating wears through to bare metal or the hex edges round off, which reduces grip on 1/16" to 7/64" fasteners.
