Wera Kraftform Micro 12 Universal 1: Small Screws Need the Right Profiles

The small screw that matters is the one in the device you intend to work on, not the number on a kit's label. Wera's Kraftform Micro 12 Universal 1 offers twelve fixed drivers across four profile groups. The useful first step is to compare that exact list with your expected fasteners.

This is model 05073675001, shown in the original gallery with its folding pouch. Its attraction is a selection of dedicated small drivers plus a handle layout meant for fingertip turning. Universal is the set's name, not evidence that it contains every profile used in modern electronics.

Read the twelve-driver list first

Wera's exact datasheet lists Phillips PH 00 and PH 0, TORX TX 5 and TX 6, five slotted drivers and three metric hex drivers. The slotted widths are 1.5, 1.8, 2, 2.5 and 3 mm; the hex sizes are 0.9, 1.5 and 2 mm. The gallery's contents image makes those groups visible before purchase.

That coverage is the first buying reason when the listed profiles match your work. Dedicated drivers can be selected from the pouch without changing a separate bit holder. It is a particular collection to evaluate, rather than a claim that a larger count automatically delivers better coverage.

For slotted screws, width is only part of the match: the datasheet also specifies blade thickness. Check the full dimensions where fit depends on them. If the needed profile is absent, another size in the pouch does not become a substitute simply because it looks close.

A rotating cap supports a different turning grip

The second buying reason is the handle arrangement. Wera describes a free-turning cap, a turning zone below it and separate zones nearer the blade. The design lets the supporting hand position and the turning part of the handle serve different roles.

That is worth assessing if your existing full-size driver feels poorly suited to small fasteners. It is also something to compare with a precision driver you already own. We have not timed repairs or measured a reduction in grip changes, so the reason to consider this set is the visible layout and documented design.

A precision handle still requires the correct tip and appropriate force for the actual fastener. These tools do not provide a specified torque setting. For equipment that calls for a controlled tightening value, the requirement remains separate from the choice of handle.

Holding is a feature of the TORX pair

The exact contents identify TX 5 and TX 6 as TORX HF drivers with a holding function. That can be relevant to a buyer handling matching small TORX screws, but it should not be extended to every screwdriver in the set. The Phillips and slotted drivers are not listed as HF.

Likewise, this contents list is not a promise of security-TORX, pentalobe or tri-wing coverage. A device name alone will not settle the needed profile. Check the fastener or its service documentation and confirm the particular set being supplied.

The manufacturer describes electronics applications, yet that phrase does not establish electrical insulation or an ESD rating for this kit. Choose around the stated tool specifications and the work's requirements. This article does not offer instructions for working on powered equipment.

The pouch makes coverage easier to keep together

The original image shows the fixed drivers organized in a folding pouch. Wera also documents profile color coding and size markings. Those features make the collection easier to inspect as a group; the printed size remains the reference when choosing a tool.

Consider whether the twelve listed drivers fill genuine gaps in your existing kit. If you mostly need a different profile, a matched individual driver or a differently specified set may be the more focused purchase. Keeping unused tools together is not the same as gaining the coverage you need.

Choose this Micro set when its exact sizes, fixed-driver arrangement and rotating caps align with recurring small-screw work. The model's clear contents are more useful than a blanket promise to repair every device.
