Value Collection 315-1264 Round Die 11/16-20 Uns Hss

Product Description

The VALUE COLLECTION 315-1264 is a round threading die designed to cut 11/16-20 UNS external threads on cylindrical stock. Manufactured from high-speed steel (HSS), it maintains cutting edge hardness under the heat generated during threading operations. The adjustable design allows the technician to fine-tune the die diameter for a closer or looser thread fit, and the right-hand thread configuration covers the vast majority of standard fastener applications. This die is used by machinists, maintenance technicians, pipefitters, and trade professionals who need to cut or restore external threads in a shop or field setting.

This die is suited for cutting 11/16-20 UNS right-hand external threads on bolts, rod stock, and fittings. The 11/16-20 designation indicates a 0.6875-inch nominal diameter with 20 threads per inch, a fine-pitch UNS thread form common in precision mechanical assemblies and specialized fastener applications. It is typically used in a round die stock holder of the appropriate diameter. Suitable for production threading and thread restoration work on steel, aluminum, brass, and similar machinable materials.

Key Features

• High-speed steel construction retains hardness and edge life during high-heat threading operations
• Adjustable die body allows thread fit to be tuned for tolerance control
• Right-hand thread direction matches standard fastener convention
• UNS thread standard — 11/16-20, fine pitch at 20 threads per inch
• Round die form fits standard round die stock holders

Compatibility

Designed as an OEM-style replacement or standard round die for use in any round die stock holder sized to accept this die form. Specific holder size compatibility should be confirmed against the die outside diameter before installation.

Installation Notes

Round dies are installed by machinists or maintenance technicians using a round die stock holder of the matching size. Apply cutting fluid liberally to the workpiece before threading to reduce heat buildup and extend die life. Ensure the workpiece diameter is turned or ground to the correct major diameter for the thread form before starting the die. Reverse the die periodically during threading to break chips and prevent binding.
