Confirm both the thread and the die holder fit
This HSS round die range covers M3-M30 external thread requirements. The thread designation and the outside dimensions of the die describe different things: provide both when you need a replacement die for an existing holder.
Specify coarse or fine pitch explicitly and include the required die outside diameter and thickness. For a holder, browse tap wrenches and die stocks. For a mixed workshop assortment, compare tap and die sets.
Request a quotation with the product name, required sizes and quantity. Include your destination and any packaging or marking requirements so they can be checked with the quotation.
