Flat End Hex L-Key Set with Holder, 13-Piece (0.050 - 3/8 in.)

• Tight Fit with Fasteners – In order to create a reliable, tight fit with fasteners, our L-keys are slightly larger in size with narrower tolerances than most competitors that follow the ASME standards • Two Measures of Tolerance Control – We measure our hex key tolerances from point-to-point and side-to-side to ensure the highest standards of dimensional accuracy and consistency • 8660 Steel – We make our L-keys with 8660 nickel chromium molybdenum steel that's heat-treated to 54–58 HRC to produce tools that are hard, but not brittle • Corrosion-Resistant Finish – We coat all of our keys with a durable manganese phosphate finish that's resistant to corrosion • Clear Markings – With the exception of the smallest sizes, Tekton L-key sizes are marked in two ways: with a high-visibility laser marking and a stamped marking
The Tekton 13-Piece Flat End Hex L-Key Set includes 0.050–3/8 inch flat end hex L-keys with a holder. The keys are made from 8660 nickel chromium molybdenum steel that's heat-treated to 54–58 HRC. The keys are coated with a durable manganese phosphate finish that's resistant to corrosion. With the exception of the smallest sizes, Tekton L-keys are marked in two ways—both with a high-visibility laser marking and a stamped marking (the 0.050 in. key is too small to laser mark and the 0.050 in., 1/16 in., and 5/64 in.keys are too small to stamp). The durable hex key holder has self-aligning key slots that allow keys to be removed and inserted without moving others out of the way.
