Yhdistelmäavain Bahco 111M-5.5 metrinen

The Bahco 111M-5.5 combination wrench is a compact metric hand tool designed for general mechanical work and precise tightening or loosening of nuts and bolts with a 5.5 mm head. Manufactured from chrome alloy steel and finished with chrome plating, the wrench combines durability with corrosion resistance while keeping a lightweight profile for comfortable handling. Its closed-ring end provides a secure fit on fasteners, and the open-end gives quick access in confined spaces.

Advantages

The chrome alloy steel construction ensures high strength and wear resistance, extending service life under frequent use. The chrome finish protects against rust and simplifies cleaning. Its small size and low weight make it easy to carry in a pocket or tool roll and to use in tight or awkward positions. The combination of open and ring ends provides versatility for both rapid adjustment and torque application.

How to use

Select the Bahco 111M-5.5 for fasteners that match the 5.5 mm size. Use the open end for quick placement and initial turning where space allows, and engage the closed ring end to apply higher torque or to avoid rounding the fastener head. Apply steady force aligned with the wrench body; avoid sudden impacts. For best results, ensure the wrench fully seats on the fastener before applying torque and reposition the wrench rather than forcing it at an angle.

Recommendations

Keep the wrench clean and dry after use; occasionally inspect for wear or deformation. Store in a tool pouch or rack to prevent corrosion and damage. Do not use the wrench as a hammer or pry bar and avoid exceeding recommended torque for 5.5 mm fasteners to prevent tool or fastener damage.
