TEKTON Ball End Hex L- Key Set with Holder, 10-Piece (1.3-10 mm)

Tekton 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.

• Marked with a high-visibility laser marking and a stamped marking
• Tolerance is measured in 2 ways to ensure dimensional accuracy
• Durable manganese phosphate finish is resistant to corrosion
