The Facom 82H.JP9A 9 piece hexagon key set (metric) includes short arm hexagon keys: 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm and 10mm. These keys are designed for driving bolts and screws with hexagonal sockets. Constructed from silicon alloy for strength and wear resistance, they are precisely heat-treated to twist rather than break under overload, ensuring user safety. The set comes in a compact sleeve-case with a hinged flap for easy size selection and storage, keeping the keys organized. A secure fastening mechanism allows for individual hex key removal without disturbing others. The keys are resistant to chemicals and general wear and tear. They conform to NF/ISO 2936 and DIN ISO 2936 performance standards.
