Open-end and Ring Wrench 11 mm Dedra 1445

Combined open-end and ring wrench 11 mm by Dedra, model 1445, is a compact hand tool designed to tighten and loosen hexagonal nuts and bolts with an 11 mm head. The tool combines an open jaw on one end and a closed, 12-point ring on the other to provide access in confined spaces and secure engagement on fasteners. Its single-size design makes it suitable for specific maintenance tasks where an 11 mm connection is used.

Advantages

The combination of an open-end and a ring end provides versatility for different working conditions: the open end allows quick placement on fasteners and use at slight angles, while the ring end ensures fuller contact and reduced risk of rounding. The 11 mm size is common in automotive, bicycle and household hardware, making the wrench a useful single-tool solution for targeted repairs. The compact length facilitates use in tight spaces and improves control when applying torque.

Suitable for

• Automotive maintenance and light repairs
• Bicycle assembly and adjustments
• Household repairs and furniture assembly
• Workshop tasks and equipment maintenance

How to use

Select the 11 mm combined wrench when working with nuts or bolts sized for an 11 mm head. Position the open end over the fastener to start loosening or tightening where quick placement is needed, or use the ring end to obtain a more complete engagement and reduce the chance of slipping. Apply steady, controlled force, keeping the wrench aligned with the fastener axis to avoid rounding. For confined locations, use the compact profile and the angled open jaw to gain access. Inspect the fastener and tool before use to ensure correct fit and condition.

Usage recommendations

Use the ring end for final torque and where full contact is required; use the open end for rapid positioning and in situations where the ring cannot fit. Avoid using the wrench as a hammer or extension; if greater torque is required, use an appropriately sized tool or a torque wrench to prevent damage to fasteners or the tool.
