9 mm Ball End Hex L-Key
5 mm, and 2 mm are too small to stamp).3 mm, 1.050 inch and 1.•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•20-Degree Ball Angle Increases Access – Our L-keys implement a steep ball-end angle that increases your ability to access fasteners while still maintaining sufficient strength•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 – 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 (sizes 0.
