Combination wrench set Proxxon PR23821 15-piece, 6–21 mm

Proxxon PR23821 is a 15-piece combination wrench set providing metric sizes from 6 mm to 21 mm in a single compact kit. Each wrench combines an open-end and a boxed offset end, enabling access to fasteners in confined spaces as well as secure engagement on nuts and bolts. The set is intended for general mechanical, automotive, workshop and household maintenance tasks where standard metric wrenches are required.

Advantages

The wrenches are organized to cover common metric dimensions across light to medium duty applications, reducing the need to search for individual tools. The combination of open-end and box-end on each wrench allows both quick turning and higher-torque operations while minimizing rounding of fasteners. The compact 15-piece assortment simplifies storage and transport and ensures a consistent set of sizes for repair and maintenance work.

How to use

Select the correct wrench size that fits the fastener snugly to avoid rounding. Use the open-end for quick turning and initial loosening or tightening in accessible positions. For higher torque or when better grip is needed, use the box-end to fully engage the nut or bolt head. When working in confined areas, use the offset box-end to reach recessed fasteners. Store the set together to keep sizes organized and readily available for future tasks.

Usage recommendations

Inspect wrenches for visible wear or damage before use and avoid applying impact force with a hammer. For high-torque applications, consider using a tool specifically rated for such loads. Keep wrenches clean and lightly oiled to prevent corrosion and ensure smooth operation.
