Stahlwille Double Ended Open Spanner, 155mm Overall Length, Alloy Steel - 40031011

This double-ended open spanner is a hand tool designed for turning hexagonal fasteners in professional electrical, electronics, mechanical and automation environments. It is forged from chrome-alloy steel and finished in chrome to provide a Durable working surface while maintaining a slim profile suitable for confined spaces. The spanner is produced to recognised engineering norms to meet workshop and on-site needs where precise manual torque application is required.

Features & Benefits

• Double T-profile increases load capacity and reduces weight
• 15° jaw offset enables access in restricted angles
• High bend strength resists deformation under torque
• Rounded chrome finish improves grip comfort during use
• Oil-bath quenching and hardening enhance wear resistance

Applications

• Suitable for maintenance of control panels and switchgear
• Ideal for assembly tasks in mechanical workshops
• Used for wiring and Terminal work in electrical installations
• Can be used on servomotor and actuator fastenings
• Suitable for precision adjustments on automation equipment

What surface treatment protects against corrosion?

The tool is chrome-plated to provide a corrosion-resistant surface and a skin-friendly feel during repeated handling.

How does the design prevent jaw deformation under load?

Reinforcement at the junction of jaw and shaft Plus the double-T cross-section increases stiffness and reduces the risk of permanent bending.

What standards govern the tool’s geometry and interchangeability?

It is manufactured to multiple DIN and ISO dimensional standards ensuring consistent jaw fit and compatibility with metric fasteners.
