Metric Left Hand Hand Taps

Shop high-speed steel (HSS) metric left hand taps for cutting new internal metric reverse threads or repairing existing left-hand threaded holes. These specialty taps are used in machinery, industrial equipment, fabrication, and maintenance applications requiring counterclockwise-tightening fasteners.

Choose the correct metric diameter and thread pitch, such as M6 x 1.0 LH or M8 x 1.25 LH, and verify the required tap style before ordering. Need help determining the matching drill size? Use our Metric Tap Drill Calculator or consult our Tap and Drill Chart.
