Includes 10-pc. flat end hex L-keys: 1.3, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10 mm; Red 10-tool L-key Holder
Tight Fit with Fasteners – In order to create a reliable, tight fit with fasteners, our L-keys are slightly larger in size with narrower tolerances than most competitors that follow the ASME standards
Two Measures of Tolerance Control – We measure our hex key tolerances from point-to-point and side-to-side to ensure the highest standards of dimensional accuracy and consistency
8660 Steel – We make our L-keys with 8660 nickel chromium molybdenum steel that's heat-treated to 54–58 HRC to produce tools that are hard, but not brittle
Corrosion-Resistant Finish – We coat all of our keys with a durable manganese phosphate finish that's resistant to corrosion
Clear Markings – With the exception of the smallest sizes, Tekton L-key sizes are marked in two ways: with a high-visibility laser marking and a stamped marking
