HSS 1/4-20 UNC Left Hand Thread Die - US Stock

This is a new high-speed steel (HSS) die for cutting 1/4-20 UNC left-hand threads.

Left-hand threads are those that tighten when turned counter-clockwise.

They're used in specific applications where vibration might loosen a standard right-hand thread, like on some clutch parts, machinery adjustments, or custom projects.

This die is ready to ship from US stock, so you won't be waiting forever.

It's a basic, unbranded tool but it's made from solid HSS and will get the job done when you need to create that special left-handed thread.
