Metric Insulated Angled Socket Wrenches for Working at Height Secure Tools provide a wide selection of metric insulated angled socket wrenches for working at height. Available in a range of metric measurement sizes, angled socket wrenches let you turn nuts and bolts more easily than a regular wrench. Manufactured using only the highest-quality materials, our angled socket wrenches are tough and built to deliver decades of hard-wearing use– even in arduous work conditions. Moreover, the inclusion of top-grade insulation in the design protects against electric shock and arcing up to 10,000 volts. If that’s not safe enough, each metric insulated angle socket wrench comes fitted with a solid open ring attachment point too, offering you a secure place to tether the tool to your harness and prevent accidental droppages when working from height.
