Wiha Tools 33403 T-handle Hex Key 3 Mm Metric

Product Description

The WIHA TOOLS 33403 is a T-handle hex key designed for trade professionals who need firm torque control in tight or recessed fastener locations. Built from alloy steel with a chrome finish, this metric hex key features a 3 mm tip size and a short-series 100 mm long arm. The T-handle configuration distributes hand pressure evenly across the grip, reducing fatigue during repetitive fastening tasks. HVAC technicians, electricians, plumbers, and mechanical contractors reach for T-handle hex keys when standard L-keys do not provide enough leverage or control.

This short-series key is suited for applications where access is limited but torque demand is moderate to high. The 100 mm arm length allows the tip to reach into recessed bolt heads, set screws on motor shafts, equipment panels, and valve assemblies common in mechanical and electrical trade work. The metric 3 mm tip size is a frequently used size across European-standard and metric-fastened equipment found in residential and light commercial systems.

Key Features

• T-handle design delivers balanced grip and high torque output compared to standard L-style hex keys
• 3 mm metric tip fits common metric set screws and socket-head cap screws
• Alloy steel construction with chrome finish for corrosion resistance and durability
• 100 mm arm length reaches recessed and hard-to-access fasteners
• Short-series form factor for use in confined spaces

Compatibility

Designed as a standard metric T-handle hex key for use with 3 mm hex socket fasteners across a wide range of mechanical, electrical, and HVAC equipment.

Installation Notes

T-handle hex keys are used by licensed HVAC technicians, electricians, plumbers, and mechanical contractors for fastener installation and removal. Always de-energize or shut off the equipment being serviced before accessing internal fasteners. Confirm the tip size matches the fastener recess before applying torque to avoid stripping the drive socket. Do not use extension cheater bars on T-handle hex keys, as this can exceed the tool's designed torque range.
