  • High-speed steel construction extends die life

  • 38 mm diameter suits M38 x 4 threads
  • California Proposition 65 warning for chemical hazards

Threading die M38 x 4

This 38 mm high-speed steel round adjustable die cuts external threads to a M38 x 4 pitch. It is intended for maintenance and repair work on pipes, rods or studs where a precise, repeatable thread form is required. The die suits professional mechanics and fabricators who need reliable thread cutting in steel and similar materials.

Adjustment and wear life

The die is chamfered on both faces with a 2 to 3 thread lead on one side and a 1 to 1-1/2 thread lead on the other for starting close to a shoulder. A fine-pitch adjustment screw opens or closes the die halves to control thread fit and compensate for wear. The slot is beveled so the adjusting screw can be removed when the die is used in a machine holder.

Replaces worn or fixed dies

This adjustable die replaces fixed round dies that cannot be compensated for wear, restoring accurate thread dimensions without buying a new tool. The jump is worth it when thread fit must be tightened over repeated use or when a single die must cover a range of fit classes. California Proposition 65 warnings apply.

Questions about this item

How do I install the 38 mm HSS round adjustable die in a die stock, and what step is often missed?

Insert the die with the 2 to 3 thread chamfer facing outward for starting threads. The beveled slot must align with the holder's adjusting screws so the fine pitch screw can be removed for machine adjustment.

What maintenance or replacement will this 38 mm HSS die need over time?

The high speed steel cutting edges wear gradually; replace the die when threads become undersized or show excessive tear-out. No lubrication points or consumable parts exist on the die itself.

What limit appears first when using this 38 mm die continuously on stainless steel?

Heat buildup in the high speed steel body reduces cutting efficiency and accelerates flank wear, making thread quality the first sustained-use constraint.
