Key Features of the Wera Tool-Check PLUS 1

6° Return Angle

At 3.43in long, the drop-forged Zyklop Mini 1/4" ratchet delivers a 6° return angle, which is finer than most full-size ratchets. It’s useful in confined spaces like inverter enclosures and battery compartments.

Socket Compatibility via 870/1 Adapter

The included 870/1 adapter converts the ratchet's 1/4" hex chuck to a 1/4" square drive, for use with all seven Zyklop sockets. 

Seven Zyklop 1/4" Sockets

Chrome-vanadium sockets from 5.5mm to 13mm work with M3 through M8 fasteners and many electrical components. Each socket includes color-coded size markings for quick identification.

28 BiTorsion Bits From Five Drive Profiles

Bit profiles include Phillips (PH1-PH3), Pozidriv (PZ1-PZ3), TORX (T10-T40), TORX BO (TX10-TX30), slotted (1×5.5), hex socket (5.5-13mm), and more.

Bitholding Screwdriver and Rapidaptor Holder

The Kraftform screwdriver provides a comfortable grip for direct hand driving, and the Rapidaptor provides a quick way to switch bits.

Secure and Compact Case

The included case features locks which hold the components in place and slide back for easy access when needed.The kit weighs just about 1lb and is small enough to fit in a jacket pocket.
