Stahlwille Ring Spanner, 16x17mm size, 255mm Overall Length - 41041617


This ring spanner is a hand tool designed for fastening and loosening hexagonal nuts and bolts in industrial environments. It combines a dual-size boxed end with an angled head profile to access confined or recessed fasteners while maintaining contact across six grip points. The tool is suited to metric systems and intended for professional tasks in automation, electronics, electrical and mechanical workshops.

Features and Benefits:


• Chrome finish resists surface corrosion and eases cleaning
• 6-point profile reduces rounding and increases contact stability
• Offset head at 15° improves access to tight or obstructed fasteners
• Precision manufacturing conforms to ISO tolerances for accurate fit
• Chrome alloy steel construction delivers dependable torque transfer

Applications


• Suitable for assembly and maintenance of control cabinets in automation
• Used for tightening panel fixings in electrical enclosures
• Ideal for mechanical plant maintenance where recessed nuts occur
• Can be used for repair and installation tasks on electronic housings

Which material family composes the body and what is the result?


The bar is MADE from chrome-alloy steel, providing a balance of strength and resistance to wear during repeated use.

Which design standards has it been produced against?


Manufacturing and dimensional aspects comply with standards including ISO 10104, ISO 7738, DIN 838, ISO 10102, DIN 3113, DIN 3110 and DIN EN ISO 9001.
