Ring‑open combination ratcheting wrench set STAHLWILLE 5-piece SW 8–19, reversible, length 295 mm, model 96411705

Five-piece STAHLWILLE ring-open combination ratcheting wrench set covering metric sizes SW 8–19. Each tool combines a reversible ratchet ring on one end and an open-end jaw on the other, providing a versatile alternative to separate spanners and ratchets. The set is designed for repeated use in mechanical, automotive and industrial maintenance where efficient tightening and loosening of nuts and bolts is required. Wrenches are finished for workshop durability and sized to offer good leverage while working in common confined spaces.

Advantages

The reversible ratcheting head enables continuous turning without repositioning on the fastener, speeding up repetitive operations. The open-end side gives access to fasteners in tight or partially obstructed positions where a ring cannot reach. Uniform overall length (295 mm where specified) delivers consistent leverage across sizes and helps maintain control during high-torque applications. Precision-machined heads ensure accurate fit on metric fasteners, reducing rounding and wear.

Suitable for

• Automotive repair and service
• Machine and equipment maintenance
• Assembly and disassembly of mechanical components
• Workshop and industrial maintenance tasks
• Situations requiring quick ratcheting access in confined spaces

Key specifications

• Set composition: 5 ring-open combination ratcheting wrenches
• Metric sizes included: SW 8, 10, 11, 13, 19 (typical size spread for SW 8–19)
• Reversible ratcheting mechanism in ring end for continuous turning
• Open-end jaw on opposite side for angled or limited-access fasteners
• Overall length: approximately 295 mm (specified for each wrench)
• Material and finish: hardened, precision-machined alloy steel with workshop-grade surface treatment

How to use

Select the wrench with the correct metric jaw size and place the open-end or the ring end onto the fastener. For rapid turning use the ring end with the reversible ratchet engaged in the required direction; flip the ratchet direction where necessary to alternate between tightening and loosening. Use the open-end where the ring cannot fit or when access is limited. Apply steady, controlled force and avoid sudden impacts; do not use the open end with cheater bars or extensions unless the tool is specified for such loads.

Usage recommendations

Regularly inspect the ratcheting mechanism for debris and wear, and keep the wrench set clean and lightly lubricated to maintain smooth operation. Store the tools in a dry environment to prevent corrosion and maintain precision fit on fasteners.
