Technologien und Leistungsmerkmale


The AS-Drive® profile enables highforce transmission without damaging the fasteners. While the force acts on the fl­ats of the screws, the corners are left free and are not rounded off.

High Performance Quality (HPQ®)

High-performance steel, extremely resilient, yet thin-walled and ideal for working in confined spaces.

Double T-profile.

The double T-profile used for the STAHLWILLE open-jaw and ring spanners saves material where it is not needed and guarantees two things at once: peak dimensional stability and extremely low weight, whichever spanner size you pick up. As a result, tool-kits from STAHLWILLE weigh considerably less. But that is not all: the double T-profile from STAHLWILLE fits snugly in the hand, allows fatiguefree working and can be gripped comfortably and safely. This also increases user safety.

More Choice.

As one of only a few manufacturers, STAHLWILLE offers a comprehensively diverse range of metric, imperial, spline drive and TORX® spanners.


Extremely thin-walled rings facilitate work in confined spaces. In addition, the rings are higher than standard nuts – which prevents the spanner seizing on the nut.

More Accurate.

Our very tight manufacturing tolerances and reproducible dimensional accuracy ensure that one STAHLWILLE spanner is as close-fitting as the next. In this way, both open-jaw and ring spanners will always firmly hug the fastener head – for excellent power-lock.
