HSS 7/8-20 UNEF Tap And Die Set – Right Hand, Standard SAE Thread

This is a tap and die set for 7/8-20 UNEF threads.

UNEF stands for Ultra Extra Fine, so this is a specialized thread.

Both the tap and die are right-hand thread and made from HSS (high-speed steel).

They're for standard SAE measurements.

The set includes one tap and one die.

They're brand new, made of metal, and come from a US stock.

If you need to cut or clean up this specific fine thread, this is the tool.

The manufacturer part number doesn't apply, and there's a 1-month warranty.
