From ITL, these insulated 3/8in Drive Sockets are designed for professional use where certified electrical insulation is required. Fully insulated and made from injection moulded nylon thermoplastic, each socket is 100% tested to IEC60900 (Category C) and ASTMF1505, offering added confidence when working in demanding environments. Built to withstand extreme impact and abrasion, the sockets are also flame retardant. ITL tools are 100% tested using 1000 volts for 3 minutes while submerged in water, and are Category C impact tested for operation across a greater temperature range from -40ºF to +158ºF (-40ºC to +70ºC). A lifetime guarantee covers both the tool and its insulation.
