Maximum versatility with four sizes

Practical benefits

Four sizes in one wrench: Incorporating 30, 32, 34, and 36 mm profiles into a single tool lets you work across multiple fasteners without switching tools.
Fast ratcheting in tight spots: The compact 5° operating angle combined with a quick-reverse lever enables you to turn fasteners efficiently in confined spaces.
Bahco Dynamic-Drive fastener protection: The 12-point profile grips the flats of the fastener rather than the corners, ensuring you minimize wear and rounding under heavy loads.

In a nutshell

The right choise for

Tackle demanding heavy-duty assembly and maintenance tasks efficiently with the Bahco S4RM-30-36 ratcheting ring wrench. Combining four large sizes (30, 32, 34, and 36 mm) in a single tool, it saves valuable space and weight in your toolkit. Its 360 mm length delivers generous leverage to break loose stubborn fasteners with less physical effort. When working in tight machinery or structural spaces, the 5° action angle and integrated reversing switch allow smooth, continuous ratcheting without removing the wrench from the fastener. Furthermore, the 12-point Dynamic-Drive profile grips the flats to protect heavy-duty nuts and bolts against wear and rounding.
