1/2 Inch Flat End Hex L-Key

•High Leverage –We designed these L-keys to be longer than most other ‘jumbo’-sized keys in order to increase leverage when 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
