Set of hex keys with diamond tip Fervi 0558/EM

What it is

The Fervi 0558/EM diamond-tip hex key set is a range of Allen keys in sizes 1.5 - 2 - 2.5 - 3 - 4 - 5 - 6 - 8 mm, with a diamond-coated tip that increases friction on the screw and reduces the risk of slipping during tightening. This feature improves grip on socket head screws, particularly when high torque is needed or the screws are hard to shift. The set is compact, with a gross weight of 0.15 kg and a pack size of 160x50x40 mm.

A hex key is an L- or T-shaped male key, hexagonal or Torx, that fits into the recess in the screw head to tighten or loosen it.

What it is for

Used for assembly work and for tightening nuts and bolts where torque must be accurate and repeatable.

How to use it

Choose the exact size and profile of the recess and insert the key fully so as not to damage the head. To break loose or tighten, put the short arm in the screw and lever on the long arm; for fast driving or awkward spots, use the long arm or the ball end. Do not extend the leverage with tubes, and replace the key when its edges are rounded.
