High Leverage
We designed the keys to be longer to increase leverage where it matters.
Tight Fit with Fasteners
We precisely manufacture our hex key geometry on the large end of the applicable range, resulting in less slop in fasteners.
Two Measures of Tolerance Control
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.
Refined Edges
Tekton keys have slightly chamfered edges (except sizes that are too small to be chamfered: 1.3 mm, 1.5 mm, 2 mm, 0.050 in., 1/16 in., and 5/64 in.) and a smooth top face to optimize engagement with fasteners.
Materials and Finishes
Maximum Torque Strength
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. As a result, the maximum torque of the L-keys consistently exceeds the ASME standards for minimum torsion load and the ISO standards for minimum proof torque.
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—both with a high-visibility laser marking and a stamped marking.
