Overview

• High Leverage – We designed these L-keys to be longer in the largest sizes to increase leverage where it matters
• Tight Tolerances – We measure our hex key tolerances in two ways, from point-to-point and side-to-side, to ensure the highest standards of dimensional accuracy and consistency
• 6150 Steel – We make our keys with 6150 chromium vanadium steel that's heat-treated to 44-50 HRC to produce tools that are hard, but not brittle
• Corrosion-Resistant – We coat all of our keys with a durable manganese phosphate finish that’s resistant to corrosion
• Clear Markings – Tekton L-key sizes are marked in two ways, with a high-visibility laser marking and a stamped marking
