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

This offset ring spanner is a metric hand tool designed for accessing fasteners in confined or recessed spaces where a straight spanner would not engage effectively. It combines a staggered head profile with a rounded finish to allow clearance over obstructions while maintaining firm contact with hexagonal nuts and bolts in industrial electrical, mechanical, automation and electronics environments.

Features and Benefits:

• 6-point ring geometry reduces cam-out and improves torque transfer
• 15° offset angle enhances access to recessed fasteners
• Alloy steel construction offers Durable load-bearing capacity
• Complies with relevant international standards for dimensional accuracy
• Round finish eases rotation in confined working envelopes

Applications

• Suitable for maintenance of control cabinets and panelwork
• Ideal for assembly tasks in automation equipment framing
• Used with machine tools where flank clearance is limited
• Can be used for electrical enclosure fastening in production lines

What sizes are available for tight-clearance fastening?

The tool covers adjacent metric sizes 16mm and 17mm for use where two close sizes are commonly required.

How does the tool help when working around protruding components?

The 15° head offset provides lateral clearance so users can engage fasteners despite nearby cables or brackets.

Which material characteristic supports repeated workshop use?

The alloy steel composition gives the spanner mechanical strength suited to frequent torque application without Rapid wear.

How is compatibility with industry tooling standards ensured?

The spanner meets multiple DIN and ISO standards for ring spanner geometry and dimensions, ensuring interchangeability with standard fasteners and fittings.

Standards
