Value Collection 84035742 Round Die 5/16-72 1in Od Hss

Product Description

The VALUE COLLECTION 84035742 is a round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. Built from high-speed steel (HSS), it maintains cutting edge hardness under the heat generated during threading operations. The die is adjustable, allowing the operator to fine-tune thread fit by opening or closing the die body with a set screw before or during use. It cuts a 5/16-72 UNS right-hand thread and measures 1 inch in outside diameter, making it compatible with standard 1-inch die stocks and holders used in trade and production environments. Machinists, tool and die workers, and maintenance mechanics are the primary installers.

This die is suited for threading operations that require the fine 72 threads-per-inch pitch of the 5/16-72 UNS thread form. The fine pitch is commonly specified in precision instrument work, optical equipment, and specialty fastener applications where a coarse thread would not provide adequate holding strength or adjustment resolution. The 1-inch OD fits a widely available die stock size, reducing the need for specialized tooling. It is appropriate for bench work, lathe tailstock use, and hand-tapping applications in both shop and field maintenance settings.

Key Features

• High-speed steel construction resists heat buildup and maintains sharp cutting edges through repeated use
• Adjustable die body allows fine-tuning of thread fit without changing tooling
• 5/16-72 UNS thread form provides fine pitch for precision and specialty fastener applications
• 1-inch outside diameter fits standard die stocks and holders
• Right-hand thread direction follows standard threading convention

Compatibility

Designed as an OEM-style replacement or standard tooling addition for use in 1-inch round die stocks that accept dies conforming to the UNS thread standard.

Installation Notes

Secure the die firmly in the die stock before beginning any threading pass. Apply cutting oil liberally to the workpiece and die to reduce friction and extend tool life. Back off the die periodically during threading to break chips and prevent binding. Inspect the die for chipping or wear before each use, as a damaged cutting edge will produce out-of-tolerance threads.
