Ring‑Maulschlüssel‑Satz 12‑teilig Proxxon SlimLine 23816 – combination wrench set, 12 pieces

Proxxon Ring‑Maulschlüssel‑Satz SlimLine 23816 is a 12-piece combination wrench set designed for mechanical and maintenance work. Each wrench combines a ring end and an open end in a slim profile that improves access in confined spaces. The set is intended for workshop use where reliable hand tools are required for tightening and loosening threaded fasteners on vehicles, machines and equipment.

Advantages

The SlimLine design reduces bulk at the head and along the shaft, enabling work in narrow gaps and between closely spaced components. Precision-formed ring ends provide positive contact with fasteners to reduce rounding and slipping, while the open ends allow quick engagement on studs and partially threaded bolts. Manufactured to a consistent geometry, the wrenches ensure uniform torque transfer and fit, supporting repeatable results during maintenance and repair tasks.

Suitable for

• Automotive repair and maintenance
• Industrial machinery service
• General workshop and fabrication tasks
• Equipment assembly and disassembly in confined spaces

Key specifications

• Quantity: 12 combination wrenches
• Design: slim profile for improved access
• Ends: ring and open-end on each wrench
• Intended use: manual tightening and loosening of nuts and bolts
• Material/finish: hardened and machined tool steel with corrosion-resistant surface (typical for hand tools of this type)

How to use

Select the correctly sized wrench for the fastener, orient the ring or open end for the best engagement and apply steady, controlled force to turn the fastener. Use the slim-profile ring end to access nuts recessed in tight locations and the open end for quick positioning on studs or partially threaded bolts. Inspect each wrench before use for wear or damage and avoid applying impact loads or using extensions that exceed the tool's intended manual torque range.

Usage recommendations

Keep the wrenches clean and lightly oiled to protect the surface finish and prevent corrosion. Store the set in an organized rack or toolbox to preserve the slim profiles and maintain correct sizes. For safe and durable performance, avoid using the wrenches as levers for prying or striking; use appropriate tools if higher torque or impact is required.
