The Tekton 23-Piece Ball End Hex L-Key Set includes the most common hex key sizes, ranging from 0.050-3/8 in. and 1.3-10 mm. The set includes durable holders with self-aligning key slots that allow keys to be removed and inserted without moving others out of the way. You can also face the L-keys to the side for a flat, low-profile organization solution. The L-keys are made from 8660 nickel chromium molybdenum steel that's heat-treated to 54-58 HRC 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. We coat all of our keys with a durable manganese phosphate finish that's resistant to corrosion. With the exception of the smallest sizes, L-key sizes are marked in two ways: both with a high-visibility laser marking and a stamped marking.
