STAHLWILLE spanners - remarkably resilient
- impressive lifetimes

High-grade chrome-alloy die-forged steel STAHLWILLE spanners are hardened in straight-through furnaces using techniques that prevent scale and decarbonised skin. An effective prevention of the "soft-skin" effect. Quenched in oil. This method prevents distortion and tension faults and guarantees closest adherence to tolerances on the jaws. Quality is assured by DIN EN ISO 9001

Conventional spanners
The point at which the jaw of a spanner meets the shaft is where the forces applied to the spanner are strongest. This fact is generally ignored in conventional spanners.
Danger of fracture is the result.

STAHLWILLE spanners
To minimise fracture danger, we concentrate the body of the material where the forces come together and reduce it where they are lowest. This results in well-balanced, sturdy tools that are, at the same time, slim and light. Their slim shape makes them the ideal choice when working in confined or awkward spaces.

• perfect fit
• perfectly chrome-plated
• concentrated forces - rings are thinner than usually possible yet stronger than any screw
• optimum bending strength thanks to double ribbing
• light-weight due to savings in the central section
• large grip surfaces ensure a steady hand and good transmission of forces
