Portable Textile Case
Designed for working in confined spaces.
Slimmer than conventional ratchets with smaller ratchet head, but longer handle length for more leverage.
Made from full metal - chrome molybdenum - for durabilty and the longest service life. Push-through square drive to change direction. The push through action is precise and smooth and will not accidentally slip due to Wera's unique technology.
Also unique among push-through ratchets is the socket or accessory locking function for complete tool security.
The ultra fine 76 tooth action 4.7, yet immensely strong ratchet mechanism is achieved by a clever multi-tooth, double twin-pawl set design.
This tool is also ideal for dusty environments in addition to all general uses.
The "sculptured" handle gives added comfort during intensive or high torque use.

    Luxurious quality.

    Enjoyable to use- the umpteenth 3/8 socket wrench I've owned, and by far, the highest quality and most solid wrench I've had. Extremely strong/solid ratcheting from the one-way rotation design, and the ball holder is a stellar fit/finish- very pleasant to use when swapping sockets. I typically loathe clever (complex) mechanisms, and the locking push-through drive pin is quite a complex little design. Yet, this solid design significantly reduces the complexity of the ratchet itself, allowing for stronger and finder ratcheting by simplifying that mechanism. Truly a very different design and improvement in the design of a socket wrench. The clean fit and finish allow for super solid feel and control when cranking, uncommon for socket wrenches.

    The Wera bug bit me over a year ago and this set didn't disappoint. I really appreciate the attention to detail, down to the extremely efficient storage cases they come in.

    Posted on Dec 15th 2015

    Push through 3/8 ratchet is great - very compact. Ratchet head is thin and narrow - has got to have one of the most compact heads anywhere. The push through moves easily but locks the socket tight. Handle is also thin but with a comfortable grip - very nice to fit in tight spaces. Brush chrome mat finish. The fabric set case is VERY compact with a nice velcro closure. Case appears sturdy but I keep the sockets and ratchet in my tool box. The extensions are the Wera type that do NOT have the socket locking button - not a problem for me. Sockets are very nice with matt finish. Set good value for the money.
