Hex Key Set 3-8mm Insulated T-Handle 5pc 150mm S2

A 5-piece insulated T-handle hex key set covering common 3mm to 8mm sizes for electrical fastening work. Built with 150mm long shafts and an S2 construction, it gives practical access to recessed fixings while keeping a steady, comfortable grip in hand.

Used for electrical installation, maintenance and service work, these keys suit electricians and others working around live components where insulated tools are required. The slim profile helps when fasteners are set into tighter spaces, panels or enclosed areas, making them useful for repeated tightening and loosening during fitting, adjustment and repair jobs.

The size range includes 3.0, 4.0, 5.0, 6.0 and 8.0mm hex keys, covering several of the common sizes needed for day-to-day electrical tasks. A T-handle layout gives better leverage and more control than a standard straight hex key, which helps reduce hand strain on longer jobs. At 150mm long, each key offers enough reach for awkward or recessed fixings without feeling overlong or clumsy to use. The insulated finish and slim shaft design make them especially handy where access and electrical safety both matter, while the included sizes help avoid switching between separate tools for common fastening work.
