Brüder Mannesmann M27405 conjunto de chaves de caixa de anel duplo 5 peças, cromo-vanádio, DIN 838, 6x7-14x15 mm

This Brüder Mannesmann M27405 set stands out with its double ring design and 75° offset, giving you reliable access to fasteners in tight spaces where a standard combination wrench would struggle. The five metric sizes cover the most common automotive and workshop tasks, while the 12-point bi-hex profile grips securely and reduces the risk of rounding off bolt heads.

Highlights

• Set of 5 double ring wrenches in metric sizes: 6x7, 8x9, 10x11, 12x13, 14x15 mm
• Made from hardened chrome vanadium steel for strength and long service life
• Matt chrome-plated finish for corrosion resistance and easy cleaning
• 75° offset ring ends improve clearance and leverage in confined areas
• Complies with DIN 838 for dimensional accuracy and performance

In daily use

Each wrench has a flat, slim profile that fits comfortably in the hand and slides easily into a tool roll or drawer. The 12-point ring ends engage fasteners at multiple angles, making it quicker to reposition the tool in tight engine bays or under machinery. The included plastic holder keeps the set organised and ready to grab when you need it.
