## Summary description

Combination wrench Proxxon Slimline 21 mm (PR23921) is a slim-profile hand tool designed for turning nuts and bolts. The 21 mm jaw fits metric fasteners; the Slimline design allows access in narrow spaces. Suitable for automotive, bicycle, and general mechanical maintenance where a compact, precise wrench is needed.

## Long description

The Proxxon Slimline combination 21 mm (PR23921) is a slim-profile hand tool designed for turning 21 mm metric nuts and bolts. The tool combines an open-end jaw on one side and a boxed ring on the other to provide both quick engagement and secure torque transfer in confined workspaces. Its low-profile Slimline head reduces bulk around the fastener, allowing access where standard wrenches may not fit, making it practical for automotive, bicycle and general mechanical maintenance tasks that require a compact, precise wrench.
Advantages
The slim-profile design reduces obstruction and enables reach into narrow gaps while maintaining sufficient strength for routine tightening and loosening. The combination of an open-end and a boxed ring offers versatility: the open end allows rapid placement on a fastener, the ring provides a full-contact grip for safer torque application. Manufactured to Proxxon quality standards, the wrench is balanced for hand use and intended to fit standard 21 mm metric fasteners without the need for adapters.
Suitable for
 Automotive maintenance in tight engine or chassis spaces
 Bicycle repair where compact tool profiles aid access
 General mechanical and household maintenance with 21 mm fasteners
 Assembly and disassembly of machinery with metric nuts and bolts
Key specifications
 Wrench type: combination (open-end and boxed ring)
 Profile: Slimline low-profile head for narrow spaces
 Material: hardened tool steel (heat-treated for durability)
 Finish: corrosion-resistant surface treatment
 Hand orientation: one-piece, fixed-size manual wrench
How to use
Select the 21 mm combination wrench and place the open end or the boxed ring over the nut or bolt head. Use the open end for quick positioning and the boxed ring when higher torque or full contact is required. Apply steady force along the handle axis to avoid slipping; for additional leverage use the boxed ring end whenever possible. After use, wipe the tool clean and store it in a tool rack or toolbox to maintain the slim profile and prevent corrosion.
Usage recommendations
Use the boxed ring for final tightening and loosening to reduce rounding of fasteners, and avoid using the wrench as a hammer or prying tool. For stubborn or rusted fasteners, apply penetrating lubricant and allow time to work before applying force. Store the wrench dry and inspect for wear periodically to ensure reliable fit on 21 mm fasteners.
