SKU KEY91002
TEKTON 41-pc. Ball End Hex and Star L-Key Set includes the most common in. hex, metric hex, and star key sizes, all stored in durable holders with self-aligning key slots that allow keys to be removed and inserted without moving others out of the way. The L-keys are made 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. The L-keys are coated 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.
