Proxxon 23820 Hook Wrench

12-piece SlimLine ring-combination spanner set in a plastic holder, manufactured to DIN 3113 and ISO 3318. Each spanner is carefully hardened and plated and shows clearly readable size markings. The ring head is offset by 15° to facilitate access in confined spaces. The holder has designated positions for each spanner and includes fixing holes for wall or bench mounting.

Advantages

The set provides twelve commonly used metric sizes in a compact SlimLine design, combining open and ring ends for versatile use. Hardened and plated finish increases corrosion resistance and durability. Clear size markings on each tool and a holder with fixing holes improve organization and accessibility in a professional workshop or for home maintenance.

• General mechanical and maintenance work
• Workshop and garage use
• Tight or confined spaces where a 15° ring offset is useful
• Organized storage on a wall or workbench using the holder

How to use

Select the spanner with the correct metric size for the fastener. Place the ring end over the nut or bolt and ensure full seating before applying torque. For restricted access, use the 15° offset ring head to obtain a better turning angle. After use, return each spanner to its marked position in the plastic holder and, if desired, fix the holder to a bench or wall using the built-in holes.

Recommendations

Do not use the spanners as hammers or for prying. Keep tools clean and lightly oiled to reduce corrosion. Inspect for wear or damage before use and replace any deformed tools to maintain safety and accurate fit.
