Value Collection 84035304 Round Threading Die 1-3/4-20

Product Description

The VALUE COLLECTION 84035304 is a round threading die designed to cut external threads on rod, bolt stock, and round bar stock. Sized at 1-3/4-20 — meaning 1.75 inches nominal diameter with 20 threads per inch — it produces right-hand threads in a single setup. The die measures 3 inches in outside diameter and is constructed from high-speed steel (HSS), which retains cutting hardness under the heat generated during threading operations. An adjustable split design allows minor pitch-diameter tuning to compensate for tool wear or to dial in thread fit. Machinists, pipefitters, and toolroom technicians install this type of die using a standard round die stock or die holder sized for a 3-inch OD die.

This die is suited for threading operations in machine shops, maintenance and repair facilities, and fabrication environments where 1-3/4-20 UNF right-hand external threads are required. The 20-thread-per-inch pitch is a fine-thread specification, commonly found in precision mechanical assemblies, heavy fastener applications, and specialized tooling where fine thread engagement provides stronger clamping force and better resistance to vibration loosening compared to coarse-thread equivalents. High-speed steel construction makes it appropriate for use on mild steel, aluminum, brass, and similar machinable materials.

Key Features

• Thread size: 1-3/4-20 right-hand external thread
• 3 inch outside diameter fits standard round die stocks sized for 3-inch OD dies
• High-speed steel construction for extended cutting life under heat
• Adjustable split design allows pitch-diameter fine-tuning
• Right-hand thread direction for standard fastener and mechanical applications

Compatibility

Designed for use in any round die stock or die holder with a 3 inch OD capacity. Cuts 1-3/4-20 right-hand external threads on machinable rod and bar stock.

Installation Notes

This die is installed and used by machinists and maintenance technicians using a round die stock rated for a 3 inch OD die. Secure the die firmly in the holder and tighten all set screws before use. Apply cutting fluid appropriate for the workpiece material to reduce heat buildup and extend die life. Inspect the die for cracks or chipped flutes before each use and replace if cutting edge integrity is compromised.
