Stahlwille Double Open End Wrench, 140mm Overall Length, 8 to 10mm² Size - 40030810

This double open-end wrench is a precision offset spanner designed for tightening and loosening metric fasteners in industrial settings. It serves technicians in automation, electronics, electrical and mechanical trades where access is restricted and controlled torque is required. The tool features an offset head profile and a chrome finish suited to workshop and site environments.

Features and Benefits:

• 15° opening angle improves access to recessed fasteners
• Double-ended design provides two metric sizes in one tool
• Chrome finish resists surface wear for extended service life
• Conforms to multiple technical standards for consistent quality

Applications

• Suitable for assembly and maintenance of control cabinets
• Ideal for adjustment of electrical panel connectors
• Used with small machinery in automation systems
• Can be used for service tasks on electronic enclosures

What size range does it accommodate for common electrical terminals?

It covers the 8 to 10mm span, matching many Terminal and connector nut sizes found in electrical installations.

How does the head geometry aid confined-space work?

The head is offset, which lets the operator engage fasteners where clearance above the nut is limited and provides improved lever clearance.

What material properties affect torque performance?

The alloy steel composition delivers higher yield strength than plain carbon alternatives, supporting elevated torque without permanent deformation.

Which specifications ensure dimensional and manufacturing consistency?

It meets recognised metric standards that govern open-end spanner geometry and quality, ensuring interchangeability and repeatable performance.
