Cle-line C65829 Round Die 7/16-20 Unf 1 in Od Hss

Product Description

The CLE-LINE C65829 is a round threading die designed to cut external threads on fasteners, bolts, and round stock. It cuts a 7/16-20 UNF right-hand thread and is built from high-speed steel (HSS) for durability under repeated use. At 1 inch outside diameter and 3/8 inch thickness, it fits standard round die stocks sized for 1-inch dies. The adjustable design allows the technician to dial in thread fit by opening or closing the die slightly through the set screw in the die stock. This die is used by machinists, maintenance mechanics, and trade professionals who need to cut or restore external threads on metal rod or fastener stock.

The C65829 is suited for threading mild steel, aluminum, brass, and similar materials in shop, field, or maintenance applications. The 7/16-20 UNF thread specification makes it appropriate for fine-thread fastener work common in automotive, HVAC equipment assembly, and general mechanical maintenance. It is used wherever a new thread must be cut from unthreaded stock or a damaged thread needs to be chased and restored. The right-hand thread direction is the standard orientation for the vast majority of fastener applications.

Key Features

Compatibility

Designed as an OEM-style replacement or standard round die for use with any die stock or die holder accepting a 1-inch outside diameter round die.

Installation Notes

Round dies are installed and used by machinists or mechanical tradespeople using a matching round die stock. Secure the die in the stock using the set screws before beginning any cut, and apply cutting fluid to the workpiece to reduce friction and extend die life. Always start the die squarely on the workpiece to avoid cross-threading. Inspect threads after cutting with a matching nut or thread gauge to confirm fit before final assembly.
