Goodluck 1/2-10 Left Hand Thread HSS Single Pass Tap - 1/2 Inch Diameter, 10 TPI

If you're working on a project that needs left-hand threads—like for a turnbuckle, a specialty repair, or certain machinery—you know how hard it can be to find the right tap locally.

This one from Goodluck is exactly what you need.

It's a brand new, high-speed steel (HSS) tap, sized at 1/2-inch with 10 threads per inch, and it cuts left-hand threads.

It's a single pass tap, meaning it's designed to cut the full thread profile in one go, which saves time and keeps things accurate.

Whether you're a professional machinist or a hobbyist tackling a tricky restoration, having the right tool makes all the difference.

This tap is ready to work, made from durable HSS to handle tough materials.

Don't settle for the wrong thread direction—get the job done right.
