Durability

Hand tools such as screwdrivers, the reliability, safety and long service life of which depend on the elasticity and at the same time the hardness of their shafts, are manufactured from specially alloyed tool steel, which makes it possible to achieve higher strength due to their higher content of selected elements. The molybdenum content of the tool steel Premium Hard chrome/vanadium steel results in their higher durability, tensile strength and ductility, while the increased silicon content ensures their higher elasticity and lower susceptibility to cracking. The appropriate hardness and resistance to wear are achieved with a corresponding carbon content.

Specially alloyed tool steel 73MoV52, according to EU directive 2000 / 53 / EC.

• 0.60 % manganese for higher tensile strength and ductility
• 1,15 % silicon for higher elasticity and lower susceptibility to cracking
• 0.70 % carbon for appropriate hardness and resistance to wear

Cold-forged steel with high quality characteristics ensures that profiles now have an even longer-lasting strength, with shafts of extraordinary hardness.

Ergonomically designed handles

The superior quality of materials used in the Unior line of screwdrivers is complemented by ergonomically designed handles to provide an excellent hold.

Three-component handle

With its combination of soft and hard surfaces, the special, three-component handle – a Unior patent – ensures comfort and efficient performance with minimum strain on the wrist while working.

Slip-proof grip

Able to fit a variety of screw profiles and exhibiting innovative three-component handles, UNIOR screwdrivers ensure great efficiency and a slip-proof grip.
