STAHLWILLE Offset Ring Spanner 16 x 17 mm, 255 mm Overall

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.

• 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

• 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

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

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

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

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