What it is
Long hex Allen keys, art. 351. Key specifications: pack (pcs) 9.
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.
