The open ring allows particularly quick, lateral access to the screw connection without having to attach it from above. This offers clear advantages in confined spaces and in applications where cables, threaded rods or surrounding components restrict access. This means that screw connections can be efficiently reached and worked on even in difficult installation situations.
Our double-ended open-ring spanner is angled by 10°, allowing better access to screw connections in confined spaces - for example, next to housings, pipes or frames. Thanks to the unequal spanner sizes, it also covers two common sizes. This significantly reduces the need to change tools, keeps the workflow smooth and is a real advantage, especially for recurring assembly and service work.
Each spanner guarantees consistently excellent quality thanks to minimal manufacturing tolerances and high reproducible precision. The jaw and ring always fit securely on the screw, ensuring optimum power transmission.
STAHLWILLE spanners feature a high-quality, non-slip surface texture that enables safe working even with oily hands. The non-slip texture increases control during handling.
The key is forged from high-quality Chrome Alloy Steel, which gives it high stability and resistance even in continuous use. It is also chrome-plated for corrosion resistance.
