Open-end wrench Proxxon 6 x 7 mm PR23830

Open-end wrench Proxxon 6 x 7 mm PR23830 is a compact hand tool designed for working with hexagonal nuts and bolts measuring 6 mm and 7 mm across flats. The tool features two fixed open jaws of different sizes on either end, enabling quick switching between fastener sizes without rotating the tool. Its small dimensions and narrow jaw profile make it suitable for confined spaces and precision tasks in mechanics, electronics and bicycle maintenance where accessibility and controlled torque are important.

Advantages

The open-end wrench provides direct contact with the flats of fasteners, reducing the risk of rounding compared with pliers in tight spaces. Its two-size design eliminates the need to carry multiple single-size wrenches for common small fasteners. The wrench’s compact form factor and slim head allow access to recessed or closely packed components. The fixed jaws deliver predictable engagement and simple, repeatable operation for light mechanical work and maintenance.

Suitable for

• Precision mechanics and watch or instrument repair
• Electronics assembly and service where space is limited
• Bicycle adjustments and small component maintenance
• Small household repairs and light mechanical tasks

Key specifications

• Open-end sizes: 6 mm and 7 mm
• Two-ended fixed open-jaw design for quick size change
• Compact, narrow head profile for limited-access areas
• Hand tool intended for manual tightening and loosening of hexagonal fasteners

How to use

Select the end with the matching size for the fastener. Place the open jaws fully over the flats of the nut or bolt to ensure full contact. Apply steady manual force to turn the fastener, keeping the wrench aligned with the fastener axis to minimize slipping. For removal or installation in confined spaces, work in short, controlled strokes and reposition the wrench as required. Do not use the wrench with excessive force, cheater bars, or impact tools.

Использование и уход

Store the wrench in a dry place and keep the jaws clean of grease and debris to maintain contact accuracy. Inspect periodically for wear or deformation before use.
