Stahlwille 40040650 4004 Single End Spanner, Special Tool Steel, 65 mm Size

Conventional spanners when force is applied to a spanner, the greatest force acts on the joint between the jaw and the shaft. Good 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 confined spaces due to their compact designs. Extremely resilient, remarkably durable. Drop-forged from good grade 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 profile. Snug-fitting, skin-friendly surfaces thanks to STAHLWILLE's rounded finish. Key benefits when tightening and loosening screws: Tougher than any bolt thanks to the forged double hex. Thinner than conventional rings – facilitating work in confined spaces. Higher than standard nuts – prevents the spanner jamming on the nut. Quality assured STAHLWILLE's Quality Assurance System was awarded an internationally recognised certificate in accordance with DIN ISO 9001 by the DQS (German Association for the Certification of Quality Assurance Systems).
