  • Fastens surface screws and nuts at six points, protecting edges.
  • Allows faster positioning and comfortable work, even with damaged screws and nuts.
  • Made from high-quality chrome-vanadium steel for durability.
  • Innovative design ensures efficient force transfer and a safety cut prevents damage to screw and nut edges.
Manufacturing Process:
  1. Cutting: Precision cutting of flat steel to minimize material waste.
  2. Forging: Enhances toughness using LASCO machines, maintaining fiber orientation for durability under heavy loads.
  3. Trimming: Removes excess material to achieve the desired shape.
  4. Perforation: Holes are made in the workpiece, either hot or cold.
  5. Burring and Grinding: Rough edges are smoothed and rounded.
  6. Machine Marking and Bending: Products are marked and bent according to standards.
  7. Broaching: Internal teeth are created using a broaching machine.
  8. Tempering: Heat treatment improves toughness and lifespan.
  9. Sanding and Polishing: Surface is prepared for protective coating.
  10. Chrome Plating: Provides corrosion resistance and a shiny finish.
Specifications and Standards:
  • Wrenches are made according to ISO 10102 and EN12540 standards.
  • Available in various sizes and configurations, including open-end, combination, and adjustable wrenches.
  • Insulated wrenches are available for additional safety, conforming to EN60900 standards.
Product Listings: Extensive tables list various wrench sizes, dimensions, and configurations, highlighting the diversity of products available.
Types of Wrenches:
  • Offset Ring Wrenches: Available in sets with different packaging options, made from chrome vanadium with a chrome-plated finish, sizes range from 6x7 to 27x32.
  • Insulated Single Offset Ring Wrenches: Designed for safety with double-layered insulation, comply with EN60900 standards, available in sizes from 10 to 24.
  • Flat Ring Wrenches: Made from chrome vanadium, have a LIFE profile, comply with DIN 837 standards, available in sizes from 6x7 to 30x32.
  • Open Ring Wrenches: Suitable for hydraulic and pneumatic installations, available in sizes from 8x10 to 30x32, made from chrome vanadium.
  • Slogging Ring Wrenches: Made from special tool steel, anticorrosive, comply with DIN 7444 standards, available in both metric and imperial sizes.
Key Specifications: Detailed tables list the dimensions (L, B, A) for each wrench type, ensuring users can select the appropriate tool for their needs.

THE MAIN COMMANDMENTS TOWARDS PERFECTION All technological processes of Unior hand tools manufacturing are carefully designed, rigorously checked and conform to demanding quality certifications. In addition to the best processes, the excellence of the final products is guaranteed by employment of superior quality materials and machines. The forging of oblong products, such as wrenches, requires several characteristic preparatory and intermediate operations before the forgings can acquire their final shape. Initially, in the forging of wrenches blanks are cut from strip by means of special blades....
