Ring spanner set, Topex 35D855 — bent/open-ended rings 6–17 mm, 6 pieces

Topex 35D855 is a set of six bent ring spanners that covers the most commonly used metric sizes from 6 mm to 17 mm. Each tool features a stepped bent head and a closed ring end that provides a secure grip on hexagonal fasteners while allowing work in confined or awkward spaces. The set is intended for general mechanical, automotive and household repair tasks that require compact, angled ring wrenches for reliable torque transfer and improved accessibility.

Advantages

The bent ring design combines a closed, full-contact ring end with a stepped offset that helps avoid obstructions and reduces the need to reposition the tool frequently. Made to standard dimensions, the spanners offer consistent fit and stable engagement with fastener heads to minimise rounding. The compact, angled profile of each wrench improves reach in tight assemblies and underbody or engine-bay locations where a straight spanner cannot be used effectively.

Suitable for

• Automotive maintenance and repair — access to bolts and nuts in engine compartments and undercarriage areas
• Mechanical assembly and disassembly tasks in workshops
• Household repairs where angled access is required, such as plumbing fixtures or furniture fittings
• Electrical cabinet and equipment work where space around fasteners is limited

Key specifications

• Set contents: six bent/open-ended ring spanners in metric sizes 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm — note: set supplied covers the 6–17 mm range (six pieces)
• Head type: stepped bent/ring ends for angled access
• Drive/contact: closed ring design for full-face engagement with hex fasteners
• Range: metric measurements covering common small-to-medium fasteners
• Use cases: hand tool for tightening and loosening bolts and nuts in confined spaces

How to use

Select the spanner whose size matches the fastener head, slide the closed ring end fully over the nut or bolt head to ensure full contact, and apply steady turning force. Use the stepped bent angle to clear nearby obstructions and reposition the tool as needed to access successive turning positions. For stubborn or rusted fasteners, combine with penetrating lubricant and apply controlled force to avoid slippage. After use, wipe clean and store the spanners in their case or a designated tool drawer to prevent corrosion.

Usage recommendations

Inspect fasteners for damage before use and ensure the spanner is seated fully to avoid rounding. Do not use the spanners as hammers or pry bars; use appropriate torque and, where required, a torque-limiting device for critical fastenings. Keep tools dry and store in a protected place to prolong service life.
