Bahco Single Ended Open Spanner Metric, 457mm Overall

This single-ended open spanner is a hand tool for tightening and loosening fasteners in industrial settings. It is produced to metric sizing and used where a single open jaw is required for access in confined assemblies. The tool’s construction suits routine maintenance and assembly tasks across automation, electronics, electrical and mechanical environments.

• Phosphate finish provides surface protection and reduced glare
• Alloy steel construction offers high structural strength
• 15° opening angle enables improved approach to tight fasteners
• Conforms to DIN 894 and ISO 3318 for standardised geometry
• Long 457mm reach facilitates access to recessed fittings
• Single open end design allows Rapid engagement and removal

• Suitable for servicing industrial machinery panels
• Ideal for electrical enclosures with limited access
• Used for assembly work in mechanical workshops
• Can be used for maintenance in automation rigs
• Suitable for adjustments on electronic test benches

The alloy steel composition delivers good rigidity and resists deformation under applied torque, maintaining jaw parallelism during use.

The phosphate coating reduces surface reflections and offers Basic corrosion resistance, helping maintain grip and visibility in varied lighting.

The spanner geometry meets DIN 894 and ISO 3318 dimensional criteria, ensuring interchangeability with fixtures and tools specified to those standards.

The 15° opening angle permits small rotational repositioning when space is limited, enabling stepwise movement on fasteners without full tool removal.
