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
We offer flexible shipping and scheduling options, up-to-date delivery estimates, and free ground shipping on any order over $99 to make sure your order gets to you on-time, for less.
