Flat wrench Proxxon 5.5 x 5 mm PR23828 for precision mechanical work

Flat wrench Proxxon 5.5 x 5 mm PR23828 for precision mechanical work is a compact hand tool designed for turning small fasteners and components in confined spaces. The wrench features two flat jaws sized 5.5 mm and 5 mm, offering close tolerances suitable for delicate mechanical tasks, model assembly, electronic repair and small household appliance maintenance. Its slim profile allows access to narrow gaps and provides controlled torque for precise adjustments.

Advantages

The flat wrench combines a low-profile design with rigid jaws to minimize slipping and rounding of small nuts and bolts. Manufactured by a specialist tool brand, it delivers consistent fit on the specified sizes and enables safe handling in miniature assemblies. The compact dimensions and smooth surfaces make it easy to store and carry, while the dual-size ends reduce the need to switch tools during fine work.

Suitable for

• Precision mechanics and watchmaking adjustments
• Model building and scale assembly
• Electronics repair and PCB component fastening
• Maintenance and repair of small household appliances
• Accessing fasteners in tight or recessed areas

Key specifications

• Wrench jaw sizes: 5.5 mm and 5 mm
• Tool type: flat/open-end wrench with two working ends
• Profile: low-profile, slim body for narrow-space access
• Intended use: manual turning of small fasteners and components
• Material and finish: durable metal construction with smooth finish for controlled grip

How to use

Select the jaw size that matches the fastener, position the flat jaw fully onto the nut or bolt to ensure even contact, and apply steady manual force to turn. Use the slim end to reach recessed or closely spaced fasteners and the alternate end for slightly different sizes. Avoid excessive torque to prevent damage to small threaded parts and ensure the tool remains seated on the fastener while turning to reduce slippage.

Usage recommendations

For best results in precision work, combine the flat wrench with adequate lighting and magnification when necessary, and keep the working area clean of debris. Inspect the wrench periodically for wear at the jaw faces; replace if deformation appears to avoid damaging delicate fasteners.
