Osg 2728200 Round Threading Die 10-32 Unf Hss Adjustable

Product Description

The OSG 2728200 is a round threading die designed to cut 10-32 UNF external threads in iron and steel workpieces. Manufactured from high-speed steel (HSS), it delivers consistent thread form and edge retention across production and maintenance applications. The die features a right-hand thread direction and an adjustable design that allows minor pitch diameter correction to accommodate tolerance requirements or compensate for wear. At 0.8125 inches outside diameter and 0.25 inches thick, it fits standard round die stocks of the corresponding size. Machinists, tool-and-die workers, and maintenance technicians install this die when threading fastener shanks, rods, or studs to 10-32 UNF specifications.

This die is suited for threading operations on iron and steel in both shop and field maintenance environments. The 10-32 UNF designation is common in precision fastener applications including instrument panels, electronic enclosures, and light mechanical assemblies where fine-thread engagement and vibration resistance are required. The adjustable feature makes it practical for both initial thread cutting and chasing previously cut threads to restore damaged profiles. Series 134 construction follows standard round die geometry compatible with common bench-mounted and hand-held die stocks.

• Right-hand thread direction per UNF standard
• 0.8125 inch outside diameter fits standard round die stocks
• 0.25 inch thickness suits both hand threading and machine applications
• Series 134 geometry for consistent 10-32 UNF thread form

Compatibility

Designed for use on iron and steel. Fits round die stocks that accept a 0.8125 inch outside diameter die of 0.25 inch thickness.

Installation Notes

Round threading dies are installed and used by machinists and maintenance technicians. Before use, secure the die firmly in the appropriate die stock and verify the set screw engages the adjustment slot. Apply cutting oil to the workpiece before threading to reduce heat and improve thread quality. Inspect the die for chipping or wear before each use, and never exceed the adjustment range specified by the die stock manufacturer.
