T7 Star L-Key

High Leverage We designed the keys to be longer in the largest sizes 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 Precise Tip Geometry The star-shaped ends have 6-lobes that are machined to precise tolerances for an exact, high-torque fit with Torx fasteners that resists camming out Maximum Torque Strength We make our L-keys with 8660 nickel chromium molybdenum steel that’s heat-treated to HRC 54-58 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 Clear Markings Tekton star L-Key sizes are marked both with a high-visibility laser marking and a stamped marking
Tekton L-keys are made with 8660 nickel chromium molybdenum steel that’s heat-treated to HRC 54-58 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. The star-shaped ends have 6-lobes that are machined to precise tolerances for an exact, high-torque fit with Torx fasteners that resists camming out. The L-keys are coated with a durable manganese phosphate finish thats resistant to corrosion. With the exception of the smallest sizes, L-key sizes are marked in two waysboth with a high-visibility laser marking and a stamped marking.
