In a nutshell

The right choise for

With the Facom 83S.4L extra-long hex key, you effortlessly reach deeply recessed socket screws that standard keys cannot access. The practical ball end allows you to work smoothly at an angle whenever direct straight-line access is obstructed. Thanks to the extra-long 138 mm blade, you gain superior leverage to loosen and tighten stubborn 4 mm fasteners with less effort. The 25 mm short arm provides optimal control and clearance in tight spaces. Finished with a durable phosphate coating, this tool is reliably protected against wear and corrosion during demanding daily maintenance and mechanical assembly tasks.
