Wiha 35393 Mini Hex L-key Set 5 Piece

Product Description

The WIHA 35393 is a 5-piece mini hex L-key set designed for precision fastening work in confined spaces where standard-size L-keys cannot reach. The set covers a hex size range starting at 0.028 inches up to 5/64 inches, making it well suited for small fasteners found in instrumentation, electronics assemblies, HVAC controls, and light mechanical equipment. The steel construction provides the rigidity needed for consistent torque application without deflection. Technicians working on equipment with miniature set screws or socket-head fasteners will find this set a practical addition to a service kit.

This mini L-key set is intended for use across trades and service environments where small hex fasteners are common. Typical applications include adjusting set screws on motor shafts, servicing control panels, and working on precision mechanical assemblies. The compact L-key form factor allows access to recessed fastener locations that are otherwise difficult to reach with larger tools. The 5-piece assortment covers the most commonly encountered miniature hex sizes in this range.

Key Features

Compatibility

Designed for use with miniature hex socket-head fasteners in the 0.028-inch to 5/64-inch hex size range across general mechanical, electrical, and HVAC service applications.

Installation Notes

Select the correct key size before applying torque to avoid rounding the fastener socket. Ensure the fastener head is clean and free of debris before seating the L-key. No special certifications or codes govern hand tool use, but always follow equipment manufacturer service procedures when adjusting fasteners on live or pressurized systems. De-energize electrical equipment and relieve system pressure before servicing any fastener on active components.
