Manufactured in chrome-vanadium steel, the best material for wrench production. Hardnesses of between HRC 42 and 50, depending on the type of wrench, and optimum hardness-strengh ratio. Widely surpass minimum tightening torques required by UNE, ISO, DIN, ANSI, etc., standards. Jaws from 4.5 mm to 50 mm.

20 different families of wrenches offer the best solutions to all problems a professional might encounter in his daily work: double open-end wrenches, combination wrenches, combination speed wrenches, flat ring wrenches, offset ring wrenches, flex head socket wrenches, half moon wrenches, ratcheting wrenches, tubular box wrenches, offset open socket wrenches, hook spanners, slogging wrenches, adjustable wrenches, hex key wrenches, ratchering ring wrenches.

The New Professional Profile (NPP) for PALMERA box wrenches redistributes forces and tensions on to the flats of the nut, thereby preventing damage and wear to the hexagonal edges of nuts and screws. Moreover, because the force is applied to the flats of the nut, this profile even enables work with nuts that have already been rounded. The NPP profile allows for thinner ring ends, facilitating wrench access in tight situations.
