Flat End Hex L-Key Set, 15-Piece 7/16-3/4 in., 11-19 mm

The Tekton 15-Piece Hex L-Key Set includes 7/163/4 inch and 1119 mm L-keys. The L-keys are made from 6150 chromium vanadium steel that's heat-treated to 4450 HRC and coated with a durable manganese phosphate finish that's resistant to corrosion. 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. The L-key sizes are marked with a high-visibility laser marking and a stamped marking.
