Wiha 36640 Torx Plus L-key IP40 Long Arm

Product Description

The WIHA 36640 is a Torx Plus L-handle hex key designed for use with IP40 Torx Plus fasteners. It features a long-arm configuration with an overall length of 4.88 inches and an arbor length of 4.6 inches, giving technicians extended reach and increased torque leverage on recessed or deeply set fasteners. The black handle provides visual identification on the bench or in a tool bag. At 0.1 pounds, it is lightweight enough for repeated use in tight service environments. Electrical, HVAC, and mechanical technicians who regularly work with Torx Plus fasteners will find this key a practical addition to their hand tool set.

The WIHA 36640 is suited for service and maintenance work on equipment that uses IP40 Torx Plus drive fasteners. The long-arm design allows the short end to be used for high-torque applications and the long end for fast spinning in open areas. Typical applications include panel assembly, equipment enclosure service, and component replacement tasks where standard Torx drivers do not fit the fastener specification. It is sold individually and requires no additional hardware.

Installation Notes

This tool is used by HVAC technicians, electricians, plumbers, and general mechanical service professionals for fastener removal and installation. Confirm the fastener drive type is Torx Plus IP40 before applying torque to avoid fastener or tool damage. Ensure the equipment being serviced is powered down and de-energized before beginning any disassembly. Store separately from impact-rated drive tools, as L-handle keys are not rated for impact driver use.
