Wiha 33485 Insulated T-handle Hex Key 1mm

Product Description

The WIHA 33485 is an insulated T-handle hex key designed for driving 1mm hex fasteners in electrical and mechanical service work. Built from Chrome Vanadium Molybdenum steel, it delivers the torsional strength and durability required for repetitive industrial use. The T-handle arm configuration provides a natural grip for applying controlled torque, while the insulated construction meets ASTM, EN, IEC, NFPA, and VDE standards — making it appropriate for use in live-voltage environments where insulated tooling is required or specified by code. The overall length is 7-7/64 inches, with a blade length of 5.9 inches, giving technicians sufficient reach into panel enclosures and tight access points.

This hex key is suited for licensed electricians, HVAC technicians, and industrial service professionals working on equipment that requires insulated tooling per NFPA 70E or equivalent electrical safety standards. Typical applications include tightening or loosening hex socket fasteners on electrical panels, motor terminal covers, control enclosures, and HVAC equipment access hardware. The T-handle arm style reduces hand fatigue during repeated fastener cycles and improves torque control compared to standard L-key profiles.

Key Features

• Insulated construction meets ASTM, EN, IEC, NFPA, and VDE standards for electrical safety
• Chrome Vanadium Molybdenum steel blade for high torsional strength and long service life
• T-handle arm design provides ergonomic grip and improved torque control
• 1mm hex size for small-fastener applications in panels and enclosures
• Overall length of 7-7/64 inches with a 5.9-inch blade for extended reach
• Red and yellow handle coloring supports quick size identification in tool rolls or kits

Compatibility

Designed for use with 1mm hex socket fasteners across electrical, HVAC, and industrial equipment applications where insulated hand tools are required.

Installation Notes

Installation and service work involving insulated tools should be performed by qualified electricians or licensed tradespeople following applicable NFPA 70E electrical safety procedures. Always verify the insulation rating is appropriate for the voltage present before using in a live-voltage environment. Inspect the insulation for cracks or damage before each use and remove from service if the insulating layer is compromised. Keep the tool clean and dry to maintain its insulating properties.
