Value Collection 84039402 Round Die 1-40 2 Inch Od Hss

Product Description

The VALUE COLLECTION 84039402 is a round threading die designed to cut external threads on rod, bolt stock, and cylindrical workpieces. Built from high-speed steel (HSS), it holds a sharp cutting edge under the heat and pressure of threading operations. The die cuts a 1-40 thread form — meaning a 1-inch nominal diameter with 40 threads per inch — using a right-hand thread direction. It features an adjustable design that allows minor diameter compensation to fine-tune thread fit. At 2 inches outside diameter, it seats into standard 2-inch die stocks and holders. This die is suited for machinists, toolmakers, and maintenance trades working with precision fastener threads.

This die is appropriate for threading operations in machine shops, maintenance and repair environments, and tool rooms where fine-pitch, large-diameter threads are required. The 1-40 thread specification is a fine-pitch designation used in precision instrument work, optical equipment, and specialty fastener applications. It is installed in a matching 2-inch die stock and driven by hand or with a tap and die set wrench. Both bench-top and in-place threading applications are typical use cases.

Key Features

Installation Notes

This die is installed and operated by qualified machinists or trades personnel familiar with threading tools and practices. Secure the die firmly in a properly sized 2-inch die stock before use. Apply appropriate cutting fluid to the workpiece and die to reduce heat and extend tool life. Inspect the die for chips or damage before each use and do not force a damaged or dull die through material.
