Threading Die for 5/16"-26 Threads
This high-speed steel round adjustable die cuts external threads on 5/16"-26 workpieces. It suits maintenance, repair and small-batch fabrication where a precise thread form is required. The adjustable design lets the user fine-tune fit for nuts or fittings. It is not suited for high-volume production threading.
1-Inch Outside Diameter with Chamfered Faces
The die body measures 1 inch across, fitting standard die stocks and holders for this size. Both faces are chamfered: one side offers a 2-to-3-thread lead for starting, the other a 1-to-1.5-thread lead for threading near a shoulder. Thread depth is limited by the die thickness, so very long threads need multiple passes.
Fine-Pitch Adjusting Screw for Fit Control
A fine-pitch screw opens or closes the die split, giving direct control over thread diameter without shims. The beveled slot allows the screw to be removed when the die is clamped in a machine holder that has its own adjusting screws. No lubricant, guide or handle is included.

Questions about this item
Will the 5/16"-26 die thread onto my existing 1" OD die stock?
Yes, the die has a 1" outside diameter so it fits standard 1" OD die stocks and machine holders.
How can I verify the 5/16"-26 threads are cutting correctly after setup?
Check that the 2 to 3 thread chamfer starts the cut cleanly and that the fine-pitch adjusting screw opens or closes the die for the required thread fit.
Does the package include a die stock or adjusting screw for the 5/16"-26 die?
The die is supplied with its own fine-pitch adjusting screw; a compatible 1" OD die stock or machine holder must be purchased separately.
