STAHLWILLE Combination spanners OPEN-BOX 21 mm

- Conventional spanners: When force is applied to a spanner, the greatest force acts on the joint between the jaw and the shaft. Standard-quality open-jaw spanners do not take this fact into consideration. In the context of normal hard work, this can lead to the tool breaking, causing considerable personal injury.
- STAHLWILLE spanners: To reduce the danger of breakage, we add more material where the greatest loads are to be found and take it away from the places that are not under such stress. In this way, we are able to manufacture extremely sturdy, slim and light tools which also facilitate working in confi ned spaces due to their compact designs.
- Extremely resilient, remarkably durable: Drop-forged from high-grade special steels. Optimum hardening in continuous furnaces with no scale build-up or skin decarburisation. Gentle quenching in oil.
- Light and easy to handle: High resistance to bending and low weight thanks to STAHLWILLE's typical
double-T profi le. Snug-fi tting, skin-friendly surfaces than
