Value Collection 315-1523 Round Die 1-1/8-18 Unef Hss

Product Description

The VALUE COLLECTION 315-1523 is a round threading die designed to cut external threads on rod, bolt stock, and cylindrical workpieces. It produces a 1-1/8-18 UNEF (Unified Extra Fine) right-hand thread and is machined from high-speed steel (HSS) for durability under repeated use. The die features an adjustable design that allows minor size correction to achieve a proper thread fit. It is used in machine shops, maintenance facilities, and trade shops by machinists, pipefitters, and industrial mechanics who need to chase damaged threads or cut new external threads to UNEF standards.

This die is suited for threading applications where a 1-1/8-inch diameter with 18 threads per inch is required. Extra-fine thread pitches are common in precision assemblies, thin-walled components, and applications where fine adjustment or vibration resistance is important. The adjustable feature makes it practical for both cutting new threads and restoring worn or damaged ones. It fits standard round die stocks sized for the appropriate die outer diameter.

Key Features

• 1-1/8-18 UNEF thread specification for extra-fine pitch external threading
• High-speed steel construction for resistance to heat and wear during cutting
• Adjustable design allows thread size fine-tuning for proper fit
• Right-hand thread direction, the standard orientation for most fastener applications
• Compatible with standard round die stocks accepting this die size

Compatibility

Designed as an OEM-style replacement or standard round die for use with die stocks sized to accept this die outer diameter in machine shop, maintenance, and trade threading applications.

Installation Notes

Round threading dies are installed and operated by machinists or qualified trade professionals using a properly sized die stock or die holder. Secure the workpiece firmly before threading and apply a cutting lubricant appropriate for the workpiece material to extend die life and improve thread quality. Inspect the die for chipping or wear before each use. Always wear appropriate eye and hand protection when cutting threads.
