Value Collection 315-1532 Round Die 1-3/16-18 Hss Unef

Product Description

The VALUE COLLECTION 315-1532 is a round threading die designed to cut external threads on cylindrical workpieces. It produces a 1-3/16-18 UNEF (Unified Extra Fine) right-hand thread profile and is machined from high-speed steel for durability across a range of metals including mild steel, aluminum, and brass. The adjustable design allows the technician to fine-tune the thread fit by compressing or expanding the die slightly within its holder. This die is a standard shop tool used by machinists, pipefitters, millwrights, and maintenance tradespeople working on precision-threaded fasteners, fittings, or custom shafts.

This die is suited for applications requiring a fine-thread pitch on larger-diameter stock. The 1-3/16-18 UNEF designation indicates an extra-fine 18-threads-per-inch pitch on a 1-3/16-inch nominal diameter, which is commonly found in precision mechanical assemblies, hydraulic fittings, and instrumentation hardware. It fits standard round die holders or die stocks sized for this die diameter. Suitable for manual hand-threading operations in maintenance, repair, and fabrication environments.

Key Features

• High-speed steel construction provides hardness and heat resistance for threading ferrous and non-ferrous metals
• Adjustable design allows minor pitch-diameter tuning for thread fit tolerance control
• Right-hand thread direction — standard orientation for the vast majority of fastener applications
• UNEF thread standard ensures dimensional compatibility with mating taps and gauges
• 1-3/16-18 thread size covers larger-diameter fine-pitch applications common in precision assemblies

Compatibility

Designed for use in standard round die stocks or holders sized to accept this die. Cuts 1-3/16-18 UNEF right-hand external threads on compatible workpiece diameters.

Installation Notes

This die is installed by a machinist or tradesperson into an appropriately sized round die holder or die stock before use. Secure the die in the holder using the set screws before beginning any threading operation. Apply cutting fluid to the workpiece and die to reduce heat buildup and improve thread finish. Inspect the die for chipping or wear before each use, and never force the die against a workpiece that exceeds its rated thread size.
