Ring Spanner Bahco 111M-27

The Combination Wrench Bahco 111M-27 is a single-piece, chrome-plated tool with a micro-matte finish and a 15° offset on both open and ring ends to improve access in tight spaces. Manufactured from high-performance alloy steel, it features a patented U-shaped shank for comfortable handling and a 12-point Dynamic-Drive™ ring profile that reduces wear on screws and nuts. Size markings are large and bi-directional for quick identification; the tool complies with ISO 691, ISO 7738, ISO 3318, ISO 1711-1 and DIN 3113 standards.

Advantages

The patented U-shaped shank design improves grip and ergonomics while the slimmer head and 15° open-end angle enhance accessibility in confined areas. The 12-point Dynamic-Drive™ profile extends fastener life by reducing rounding, and the chrome plated micro-matte finish provides corrosion resistance and a high-quality surface. Large, bi-directional size markings and high-clarity imprinting simplify tool identification. Supplied in retail packaging (SB) on a plastic info card.

How to use

Select the 27 mm end to fit the fastener securely. Position the open or ring end onto the nut or bolt ensuring full contact with the flats, then apply steady turning force. Use the 15° offset to clear obstructions and access fasteners in confined spaces; the U-shaped shank improves grip and control during operation. Inspect the tool and fastener before use and avoid using the wrench on damaged or rounded fasteners.

Recommendations

Store the wrench dry and clean to preserve the chrome finish; use appropriate personal protective equipment when working. Do not use the tool as a hammer or pry bar and replace the wrench if the imprint or profile shows excessive wear.
