Cle-line C65395 Round Threading Die 7/8-9 Unc Carbon Steel

Product Description

The CLE-LINE C65395 is an adjustable round threading die designed to cut external threads on rod, bolt stock, and fastener blanks. It cuts a 7/8-9 UNC right-hand thread profile and is manufactured from carbon steel for reliable performance in general-purpose threading operations. With a 2.5-inch outside diameter and 3/4-inch thickness, it is sized for use in standard round die stocks. The adjustable design allows the operator to fine-tune thread fit by expanding or compressing the die slightly, which is essential for achieving proper thread class on the first pass or correcting for tool wear over time. Machinists, pipefitters, and maintenance technicians install this die in production and field threading applications.

This die is suited for threading fastener-grade and structural steel rod in residential and commercial maintenance, fabrication shops, and field service environments. The 7/8-9 UNC designation makes it a common choice for heavy fastener applications where coarse-thread engagement is required. Series 0610 identifies the die family and helps match the die to the correct die stock holder for proper fit and drive engagement during operation.

Compatibility

Designed for use in standard round die stocks accepting a 2.5-inch outside diameter die. Compatible with Series 0610 die stock holders.

Installation Notes

Round dies are installed by machinists or maintenance technicians using a matching die stock of the correct outside diameter. Secure the die firmly in the stock before threading to prevent rotation or slipping during the cut. Apply cutting oil to the workpiece before and during threading to extend die life and improve thread finish. Inspect the workpiece diameter against published UNC 7/8-9 major diameter tolerances before starting to ensure clean thread engagement.
