Value Collection 314-4738 Round Die M16x1.5 Hss Left Hand

Product Description

The VALUE COLLECTION 314-4738 is a round threading die used to cut external M16x1.5 metric fine threads in left-hand orientation. Made from high-speed steel (HSS), it delivers the hardness and heat resistance needed for threading steel, stainless, aluminum, and similar materials in production or repair applications. At 0.5 inches thick, the die fits standard round die stocks designed for that profile. The adjustable design allows the technician to fine-tune thread fit by slightly opening or closing the die for tighter tolerance control or to account for material variation. Machinists, tool-and-die workers, and maintenance mechanics are the primary users of this type of tooling.

This die is suited for any application requiring a left-hand M16x1.5 metric fine external thread. Left-hand threading is commonly specified on rotating assemblies where standard right-hand threads would loosen under operational torque, such as certain spindle nuts, bicycle components, and industrial machinery retention fasteners. It is used in job shops, maintenance facilities, and field repair situations where threading a rod, bolt blank, or shaft to a precise metric fine pitch is required.

Key Features

• M16x1.5 metric fine thread form for precision-pitch external threading
• Left-hand thread direction for counter-rotation applications
• High-speed steel construction provides hardness and thermal resistance during cutting
• Adjustable die body allows minor thread fit calibration
• 0.5 inch thickness fits standard round die stocks of matching size

Compatibility

Designed for use in standard round die stocks that accept dies of matching diameter and 0.5 inch thickness. Verify die stock diameter compatibility before use, as round dies are available in multiple outer diameter standards.

Installation Notes

Threading dies are installed and operated by machinists or qualified maintenance personnel. Secure the die firmly in a properly sized die stock before use and apply appropriate cutting fluid to the workpiece to reduce heat and extend die life. Ensure the workpiece diameter is chamfered and measured to the correct major diameter for M16x1.5 before threading begins. Do not force the die if it binds — back off to break the chip and re-apply cutting fluid.
