Value Collection 315-1241 Round Die 9/16-20 Hss Adjustable

Product Description

The VALUE COLLECTION 315-1241 is a round threading die machined from high-speed steel (HSS) for cutting external threads on rod, bolt stock, and pipe fittings. Sized for a 9/16-20 thread profile to the UNS standard, this die is adjustable, allowing the operator to fine-tune the thread fit by opening or closing the die body slightly via a set screw. Right-hand thread direction is standard for the vast majority of fastener and mechanical applications. Machinists, maintenance technicians, and general metalworkers are the primary users of this tooling.

This die is suited for threading operations in job shops, maintenance and repair facilities, and light manufacturing environments. It handles the 9/16-20 UNS thread specification commonly found in automotive fasteners, hydraulic fittings, and precision mechanical assemblies. The adjustable design lets the user take a first pass with a looser fit, then tighten the die for a final finishing pass, reducing the risk of galling or oversized threads on harder stock materials.

Key Features

• High-speed steel construction retains cutting edge hardness under heat generated during threading
• Adjustable die body allows thread fit tuning without a separate adjustment tool in most standard die stocks
• 9/16-20 UNS thread size covers automotive and precision mechanical fastener applications
• Right-hand thread direction matches standard fastener convention
• Round die form fits standard round die stocks and holders

Compatibility

Designed for use in standard round die stocks sized to accept this die form. Intended for cutting 9/16-20 UNS right-hand external threads on compatible workpiece materials.

Installation Notes

Threading dies are installed and operated by machinists or maintenance technicians using a properly sized round die stock. Secure the workpiece in a vise before threading. Apply appropriate cutting fluid to the workpiece to reduce heat and extend die life. Inspect the die for chips or wear before each use, and do not force the die if it binds, as this can damage both the die and the workpiece.
