Product Overview

Features * 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
