Safety tips

  • Discard any wrench with a spread or damaged fixed jaw or a bent handle

Safety (pictures)

Don't use them to free a rusted nut or to finally tighten such a nut.

Never pull on a wrench that has a loose fit after it has been adjusted with a fastener. Always tightly adjust an adjustable wrench to fit the nut.

Never use a hammer or extension.

Wrenches should be tightly adjusted to the nut and pulled so that the force is on the side of fixed jaw.

Periodically inspect to check for damaged jaws, knurls, pins and springs. Damaged parts should be replaced.

  • 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.
