Wera Tool-Check PLUS: A Short Ratchet Swing, Not a Straight Driver

Product guide October 26, 2026

Direct bit mounting, a 6-degree return angle and seven specific metric sockets: what the original Wera 05056490001 changes in a tight screwdriving spot.

A mini bit ratchet changes how you turn a screw: the handle swings back and forth beside the fastener instead of turning a screwdriver handle behind it. The original Wera Tool-Check PLUS is a candidate for that restricted-swing job with 1/4-inch bits. Its socket selection is useful but incomplete: seven specific metric sizes, not a full size run.

This guide covers the 39-piece metric set, model 05056490001. Wera marks this original model discontinued and says a new version became available on June 1, 2025. Match the model when shopping; the details here do not describe a replacement version or promise stock.

Keep the bit close to the ratchet head

A driver bit fits directly into the 8001 A ratchet head. You do not need the longer Rapidaptor holder between them. That direct connection avoids adding the holder’s length when clearance along the screw axis is the problem.

Wera specifies a 6-degree return angle: a short backward swing resets the ratchet for the next stroke. It is not the amount of space the whole tool needs. The head, bit, handle and your fingers still have to fit, and the bit must seat correctly.

Two controls, two different jobs

The little reversing lever selects which direction the ratchet drives. The knurled wheel around the head lets your thumb turn the bit directly. Those are separate functions—not two ways to reverse it.

The wheel is useful for running a freely turning screw; the handle provides the back-and-forth ratcheting motion. Neither control measures tightening torque. If the item specifies a torque, this set alone does not provide that measurement.

Switching to sockets adds a connection

For an external-hex fastener, the included adapter connects the bit ratchet to a square-drive socket. That is different from putting a screwdriver bit directly in the head, and the adapter-plus-socket assembly needs its own clearance.

Wera Tool-Check PLUS handle, bit ratchet and seven metric sockets arranged outside their holder — The sockets are separate from the driver bits. The seven supplied sizes are listed below.

The supplied socket sizes are 5.5, 6, 7, 8, 10, 12 and 13 mm. There are no 9 mm or 11 mm sockets and no SAE sockets in this metric set. Do not read “5.5–13 mm” as continuous coverage.

The rest of the 39-piece count includes the bit ratchet, straight bit-holding handle, Rapidaptor holder, adapter and 28 bits. Several Phillips and Pozidriv bits repeat sizes; 39 pieces does not mean 39 different fastener sizes.

The reason to choose this configuration is the change in turning motion, with a small metric socket selection alongside it—not electric drive or a precision-electronics bit system. The included straight handle remains a separate option when you can approach the screw directly.
