Value Collection 03691094 Round Die 5/16-18 Unc Hss

Product Description

The VALUE COLLECTION 03691094 is a round threading die designed to cut external threads on bolts, studs, and round stock. Made from high-speed steel (HSS), it delivers the hardness and heat resistance needed for repeated use on common fastener materials including mild steel, stainless, and brass. This die cuts a 5/16-18 UNC right-hand thread and measures 0.25 inches in thickness. The adjustable design allows the operator to fine-tune thread fit by opening or closing the die slightly with a set screw. Machinists, maintenance technicians, and pipefitters use round dies like this for thread repair and fabrication work on the bench or in the field.

This die is suited for threading 5/16-18 UNC fasteners and round stock in both shop and maintenance environments. The 5/16-18 thread form is one of the most common Unified National Coarse sizes, used extensively in general mechanical assembly, structural fastening, and equipment repair. Right-hand thread direction is the standard for the vast majority of threaded fastener applications. The HSS construction makes it appropriate for use with hand die stocks as well as machine-held die holders in production or repair settings.

Key Features

• 5/16-18 UNC thread size for one of the most widely used coarse-thread fastener standards
• High-speed steel construction provides hardness and wear resistance for repeated cuts
• Right-hand thread direction matches standard fastener orientation
• Adjustable die body allows fine-tuning of thread fit and tolerances
• 0.25-inch thickness fits standard round die stocks designed for this size range

Compatibility

Designed as an OEM-style replacement or general-use round die for standard die stocks and holders that accept round dies in this size class.

Installation Notes

Round dies are installed and secured in a matching die stock before use. Ensure the die stock set screw engages the adjustment slot on the die body. Apply cutting oil to the workpiece before threading to extend die life and improve thread quality. When chasing existing threads, start the die straight to avoid cross-threading.
