Proxxon 23864 double open-end wrench 34 x 36 mm

The Proxxon 23864 double open-end wrench 34 x 36 mm is a hand tool designed for manual tightening and loosening of nuts and bolts with 34 mm and 36 mm flats. The tool features two open ends with different jaw widths, enabling fast switching between sizes without changing tools. Its compact dual-head design helps reach fasteners in confined areas and provides a direct grip for torque transfer during routine workshop, maintenance and mechanical repair tasks.

Advantages

The double open-end format offers immediate access to two common sizes in a single tool, reducing the need to carry multiple wrenches. The short, compact head geometry improves accessibility in tight spaces while maintaining a clear line for applying force. The wrench is made to provide a secure contact with flats to minimize slipping and rounding of fasteners when used correctly. Its simple, rigid construction ensures straightforward manual operation and durability under normal workshop conditions.

Suitable for

• Manual tightening and loosening of nuts and bolts with 34 mm or 36 mm flats
• Workshop repairs and routine maintenance
• Automotive and mechanical repair tasks where access is limited
• Use on machines, frames, and fittings requiring medium-to-large-sized wrenches

Key specifications

• Type: double open-end wrench with two jaw sizes
• Jaw sizes: 34 mm and 36 mm
• Material: forged steel construction for strength and rigidity
• Finish: corrosion-resistant surface treatment
• Design: compact dual-head for improved access in confined spaces

How to use

Select the correct jaw size (34 mm or 36 mm) that fits the flat faces of the nut or bolt. Position the open end fully onto the fastener so that the wrench jaws seat flush against the flats. Apply steady, controlled force in the required direction to tighten or loosen; avoid sudden impacts. If additional leverage is necessary, use a longer lever designed for wrench use or choose a different tool sized appropriately. Inspect the contact fit regularly and reposition the wrench if slipping occurs to prevent damage to the fastener.

Usage recommendations

Use the Proxxon double open-end wrench for manual tasks within its size range and avoid applying excessive torque beyond hand operation. Keep the wrench clean and periodically check for wear or deformation; replace if jaws become rounded or damaged. Store in a dry tool drawer or toolbox to maintain the corrosion-resistant finish and ensure reliable performance.
