0.050 Inch Ball End Hex L-Key
3 mm are too small to laser mark, sizes 0.â¢High Leverage â We designed the keys to be longer in the largest sizes to increase leverage where it mattersâ¢Tight Fit with Fasteners â We precisely manufacture our hex key geometry on the large end of the applicable range, resulting in less slop in fastenersâ¢20-Degree Ball Angle Increases Access â Our L-keys implement a steep ball-end angle that increases your ability to access fasteners while still maintaining sufficient strengthâ¢Maximum Torque Strength â 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 torqueâ¢Clear Markings â With the exception of the smallest sizes, Tekton L-key sizes are marked in two waysâboth with a high-visibility laser marking and a stamped marking (sizes 0.
