Wera '05020100001 6004 Joker S Self-Setting Spanner, 10-13 (7/16"-1/2"), Silber

Great really good for bolting up m16. And m20 bolts in tight spaces worth the money if you are a plumber or pipe fitter this should be in your tools bag

I had looked at these for a while and for the price I couldn’t justify buying them. Then I tried a workmate’s and was sold. I ended up buying 2 different sizes and as a pipe fitter making up valves and tightening up fittings, these are so much easier and quicker than using adjustable spanner’s. Usual Wera quality means they are a must have addition to my toolkit.

Fast delivery and brilliant bit of kit. It’s on the large side so brilliant for removing radiators and the like . Well made

Good quality as per all wera products but does take some getting used to. Once you’re used to it though they’re great. Grip is immense with no worry of it losening like on adjustable, and a great tool to have.

I first saw this spanner over here on amazon and I was a bit dubious about it. However, I decided to buy the small one, just to try it and see the concept behin it. Right after the first use I knew I was gonna buy these in all sizes. They are easy to use, made of very high quality steel and can be very handy in situations, where you can't use a socket, or a ratchet spanner. That is, because they will lock on the nut, or bolt one way very firmly, but at the same time they would skip over the sides, when turned the other way. This allows you to use them the same way, as you would use a ratchet spanner, except with these you don't have to worry abuot being able to put the actual ring of a ratchet spanner over the nut. At first, I was surprised how useful this small one was and very soon after I decided to get all the sizes in. They have prooven to be more, than my initial expectations would have been. I can truely recommend these to anyone, who cares about the quality of tools he, or she has to work with in everydays engineering tasks.

Brilliant little spanner. Does away with a lot of spanners you'd need otherwise and far easier to use than a conventional adjustable spanner.

Little disappointed with this product, a lot of money for something that is not as useful as an open ended spanner , difficult to use one handed and in tight spaces . When the nut is slack the rachit does not work

Not cheap but a great tool ease of use good grip value for money

Heavy duty wrench and can get the job done. Great for water heater flex connectors.

La llave de boca autoajustable Wera 6004 Joker L es una de las mejores herramientas que he probado. La función de autoajuste es genial, ya que se adapta perfectamente a diferentes tamaños de tuercas entre 16-19 mm (5/8"-3/4"), lo que hace que el trabajo sea mucho más rápido y eficiente, sin necesidad de ajustar constantemente la apertura de la llave. El mecanismo de retención de la tuerca funciona de maravilla, evitando que se deslice o caiga durante el uso, algo que es muy útil cuando estás trabajando en espacios ajustados o con muchas piezas. Además, el diseño compacto y robusto la hace muy cómoda de manejar, y su construcción de alta calidad asegura una larga vida útil. Si buscas una herramienta confiable, práctica y de alta precisión, esta llave Wera es una elección excelente. ¡Totalmente recomendable para profesionales y aficionados al bricolaje!

Zoals altijd is deze keer ook dit product van uitmuntende kwaliteit. Wera is echt het meest degelijke en ergonomische gereedschap

もうこれがないと作業捗らないからもう1個購入します❗️普通のモンキーでやってた時間がバカバカしいくらいですね。 これは早く施工出来るし最高👍ただし最初の慣れるまでちょっと苦戦すると思います。 似たようなモンキー今まで買ってきたがこれが1番良いです✌️

This Wera spanner is an incredibly practical and high-quality addition to my tools. The self-adjusting mechanism works flawlessly and practically replaces the need to carry a whole set of different sized wrenches. The grip on the bolts is very secure without damaging their edges. The build quality is solid, and the tool performs excellently for both fine home plumbing repairs and car maintenance. The investment in this tool is worth every penny. I am very satisfied!
