Safety (pictures)

Never use an extension or other form of lever to increase the leverage of any wrench.

Never tilt a hex wrench. The nut must be fully seated.

Never use a hammer on hex wrenches.

Never expose any wrench to excessive heat, which may change the hardness and metal structure and ruin the tool.

Wrenches should not be ground to change their shape.

Select a wrench whose opening fits exactly.

  • Long lifespan

    The wrenches are made of Premium chrome vanadium steel with a greater density at the points of the highest pressure, and such dimensioning and manufacture only increase their extreme power and durability.
  • Safety cut

    With their special safety cut, the wrenches prevent the damaging of corners and edges of the screws and nuts by distributing the force evenly over the surface away from the outer lines of the nut or screw head instead of directly on the edges.
  • Innovative design

    State-of-the art design makes Unior wrenches guarantee an accurate and efficient transfer of force to screw heads and nuts.
