Ball End Hex and Star L-Key Set with Holder, 41-Piece (0.050-3/8 in., 1.3-10 mm, T6-T50), Tekton, Mfr#: KEY91002

•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 0.050 inch and 1.3 mm are too small to laser mark, sizes 0.050 inch, 1/16 inch, 5/64 inch, 1.3 mm, 1.5 mm, and 2 mm are too small to stamp) •13-pc. ball end hex L-key wrenches: 0.050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 in. •15-pc. ball end hex L-key wrenches: 1.3, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 7, 8, 9, 10 mm •13-pc. star L-key wrenches: T6, T7, T8, T9, T10, T15, T20, T25, T27, T30, T40, T45, T50 •Black, red, gray hex key holder
