Value Collection 315-1142 Round Die 3/8-20 1 in Od Hss

Product Description

The VALUE COLLECTION 315-1142 is a round threading die designed for cutting external threads on bolts, rods, and fastener stock. Made from high-speed steel (HSS), it delivers consistent cutting performance across a range of materials including mild steel, aluminum, and brass. This die cuts a 3/8-20 UNS right-hand thread profile and features an adjustable design that allows the machinist to dial in thread fit and compensate for tool wear. The 1-inch outside diameter fits standard round die stocks and holders commonly found in most shops and field toolkits. At 0.5 pounds, it is compact enough for bench or portable use.

This die is suited for maintenance, repair, and fabrication work requiring 3/8-20 UNS threaded fasteners. Typical applications include restoring damaged threads on rod ends, threading new stock for custom fasteners, and production of replacement hardware in machine shops or MRO environments. Machinists, millwrights, and maintenance technicians are the primary users. It is equally at home in a production shop or a field service kit where on-site thread repair is required.

Compatibility

Designed for use with standard 1-inch round die stocks and die holders. Cuts 3/8-20 UNS thread form on compatible rod and bolt stock materials.

Installation Notes

Secure the die firmly in the die stock before use and ensure the workpiece is clamped or held steady. Apply cutting oil to the workpiece and die throughout the threading operation to reduce heat buildup and extend tool life. For adjustable dies, set thread fit using the adjustment screw before cutting to full depth. Inspect threads with a go/no-go gauge after cutting to verify dimensional accuracy.
