## Long description

Proxxon PR23143 is a 21 mm flat-ring combination wrench with an integrated ratchet mechanism designed for tightening and loosening hex fasteners. The tool features an open-end jaw on one side and a slim ring head with a built-in ratchet on the other, enabling continuous turning without frequent repositioning. Its flat profile improves access in tight spaces and makes it suitable for automotive, mechanical and maintenance tasks where reach and efficiency are important.
Advantages
The combination of an open-end and a ratcheting ring head allows both quick initial engagement and efficient continuous turning. The integrated ratchet eliminates the need to remove and reposition the wrench for each stroke, saving time on repetitive tasks. The flat, compact design enhances access to confined areas and reduces the risk of rounding fasteners by providing stable, even contact. The tool is made to meet professional demands for precision and durability in routine maintenance and repair work.
Suitable for
Tightening and loosening 21 mm hex nuts and bolts in automotive repair
General mechanical assembly and disassembly
Maintenance work in workshops and industrial environments
Tasks in confined or hard-to-reach areas where a low-profile wrench is required
Key specifications
Wrench type: flat combination wrench with ratcheting ring
Size: 21 mm
Head configuration: open-end on one side, ratcheting ring on the other
Profile: slim/flat design for improved access
Function: integrated ratchet mechanism for continuous turning without repositioning
How to use
Select the 21 mm wrench for the matching hex fastener. Place the open-end jaw onto the nut or bolt to apply initial torque or for use where the ring cannot reach. Use the ratcheting ring head to continue turning without lifting the tool; the ratchet allows back-and-forth movement while maintaining engagement with the fastener. Apply steady force along the wrench axis to avoid slipping and ensure accurate contact with the fastener faces. Inspect the fastener and wrench seat periodically to confirm secure engagement during work.
Usage recommendations
Use the open-end for quick placement and the ratcheting ring for repetitive turns. Avoid excessive impact or using the wrench as a hammer. Keep the ratchet mechanism clean and free of debris to maintain smooth operation, and store the tool in a dry place to prevent corrosion.
