The ITL 7 Piece Insulated T-Handle Hex Key Set is a professional-grade metric tool set designed for electrical work and live environments requiring safety-rated hand tools. Manufactured from injection moulded nylon thermoplastic, these insulated hex keys deliver robust electrical protection for contractors and electricians working on or near live circuits. Each tool in this set undergoes rigorous 100% testing to IEC60900 Category C and ASTM F1505 standards, ensuring reliable protection when working with voltages up to 1000 volts. The testing protocol includes full submersion in water during electrical testing, confirming comprehensive insulation integrity. The thermoplastic construction provides exceptional resistance to extreme impact and abrasion whilst offering flame retardant properties. Category C impact testing certifies these T-handle hex keys for operation across an extended temperature range from -40°C to +70°C, making them suitable for demanding industrial and outdoor electrical installation work. The T-handle design provides excellent torque application and control when working with hexagon socket fixings in electrical enclosures, control panels, and machinery. ITL backs these tools with a lifetime guarantee covering both the tool and its insulation, supplied in a convenient tool roll for organised storage and transport.
