Long service life
Wrenches are made of premium chrome-vanadium steel with higher density at the points of highest pressure, increasing their extreme strength and durability.
Special profile
The special profile of the wrench prevents damage to corners, edges of bolts and nuts. The distribution of force is evenly distributed along the sides away from the outer edge of the nut or bolt head and not directly on the edge.
Innovative design Unior's state-of-the-art design ensures accurate and efficient transfer of force to bolt and nut heads.
TECHNOLOGY:
PREMIUM - Wear-free reliability
For tools such as wrenches and sico pliers that need to withstand high loads, properties such as high tensile strength, adequate material stiffness with greater flexibility and the lowest possible susceptibility to cracking are particularly important. These requirements are met by premium chrome vanadium steel, an alloy tool steel with manganese, chromium, silicon and carbon. Tools made from this steel have a long service life and are the perfect choice for long-term use.
Alloy tool steel 31CrV3, in compliance with EU Directive 2000/53/EC
0.60% manganese for greater tensile strength and toughness
0.60% chromium for lower susceptibility to cracking and higher tensile strength
0.30% silicon for higher elasticity
0.35% carbon for matching tool hardness
Wrenches and wrenches made of chrome-vanadium steel with added alloy elements for even better properties are now characterized by their ergonomic shape and safe use and even higher wear resistance.
