Wiha 33487 Insulated T-handle Hex Key 3.00 Mm

Product Description

The WIHA 33487 is an insulated T-handle hex key designed for electricians and maintenance technicians working in environments where contact with energized conductors is a risk. The hex drive end accepts 3.00 mm fasteners, and the overall length measures 7-7/64 inches with a blade length of 5.9 inches. The handle is formed in a T-handle arm style, providing the torque control needed when driving hex socket fasteners in tight or overhead positions. The body is Chrome Vanadium Molybdenum steel, offering hardness and resistance to fatigue under repeated load cycles. Insulation is rated and tested to meet ASTM, EN, IEC, NFPA, and VDE standards.

This hex key is suited for electrical panel assembly, motor terminal work, switchgear maintenance, and any fastener-driving task where live-circuit exposure is possible. The red and yellow handle coloring follows conventional insulated-tool color coding, making it easy to identify insulated tools in a kit or tool bag. It is commonly used by licensed electricians, industrial maintenance techs, and service professionals working on equipment that cannot be fully de-energized during servicing.

Compatibility

Designed as an OEM-style insulated T-handle hex key for use with 3.00 mm metric hex socket fasteners in electrical, industrial, and mechanical service applications.

Installation Notes

This tool is intended for use by qualified electricians and trained maintenance technicians. Before using any hand tool near energized circuits, verify the insulation is undamaged and the voltage rating is appropriate for the application. Inspect the insulated coating for cracks, cuts, or delamination before each use and remove the tool from service if damage is found. Follow applicable NEC and NFPA guidelines when working in or around energized electrical equipment.
