4 mm Hex Key for Precision Work

This Wiha Tools hex key is a single-tip L-shaped wrench designed for metric fasteners that require a 4 mm drive. The insulated, corrosion-resistant construction makes it suitable for electrical and general maintenance tasks where non-magnetic tools are preferred.

Chrome Finish and Short Arm Geometry

The chrome-plated HAWA material resists corrosion while the short arm length of 1.125 mm provides access in confined spaces. A long arm of 4 11/16 in delivers leverage without excessive bulk, and the tool is not tether-ready or spark-resistant.

Replaces Worn or Oversized Hex Drivers

This key upgrades from rounded or ill-fitting drivers that damage 4 mm socket heads. The jump is worth it when a precise, insulated, non-magnetic wrench is required for metric hardware in tight clearances.
