TEKTON Ball End and Flat End Hex L-Key Set with Holder and Rack, 43-Piece (0.050-3/4 in., 1.3-19 mm) | KLX99301

High Leverage – We designed these L-keys to be longer in the largest sizes to increase leverage where it matters Tight Tolerances – We measure our hex key tolerances in two ways, from point-to-point and side-to-side, to ensure the highest standards of dimensional accuracy and consistency Corrosion-Resistant – We coat all of our keys with a durable manganese phosphate finish that's resistant to corrosion Clear Markings – Except for the smallest keys, Tekton L-key sizes are marked with a laser marking and a stamped marking (0.050 inch and 1.3 mm are too small to laser mark and 0.050 inch, 1/16 inch, 5/64 inch, 1.3 mm, 1.5 mm, and 2 mm are too small to stamp) Quick-Access Racks – The included racks have hex-shaped slots that make it easy to take the large L-keys in and out without resistance
