Reliable tightening with the Facom combination wrench

Practical benefits

Protects fasteners from rounding: The 12-point OGV profile applies torque across the flats, ensuring you avoid rounding nut and bolt edges during heavy tightening.
Enhanced access around obstacles: With both heads angled at 15°, you navigate tight spaces and reach recessed or closely aligned fasteners with ease.
Comfortable and safe handling: The ergonomic I-beam handle offers a secure grip while gradual deformation under critical torque prevents sudden, hazardous fractures.

In a nutshell

The right choise for

Tackle stubborn 1/2" imperial fasteners confidently with the Facom 440.1/2 combination spanner. Designed with a 12-point ogv profile, the ring head drives against the fastener flats rather than the corners, effectively preventing rounding while maximizing torque transfer. Both the open end and ring end feature a 15° offset angle, allowing you to easily bypass obstacles in tight engine bays or confined machinery setups. With an overall length of 170 mm and an ergonomic I-beam handle, this wrench provides a secure, comfortable grip and outstanding leverage for demanding mechanical tasks.
