Cle-line C65855 Round Die 3/8-16 Unc Hss Adjustable

Product Description

The CLE-LINE C65855 is a round threading die designed to cut external threads on bolts, studs, and rod stock. Built from high-speed steel (HSS), it delivers the hardness and wear resistance needed for production and maintenance threading tasks. This die cuts a 3/8-16 UNC right-hand thread and measures 0.5 inches in thickness. The adjustable design allows the operator to fine-tune the thread fit by opening or closing the die slightly using a standard die stock with a center and side-pressure screw. It is a Series 0710 die intended for use by machinists, maintenance mechanics, and trade professionals who need reliable thread cutting on inch-standard fasteners.

This die is suited for threading mild steel, aluminum, brass, and similar machinable materials in shop or field maintenance environments. Common applications include fabricating threaded rod, chasing damaged threads on existing fasteners, and producing new threaded shanks on cut bolt stock. The 3/8-16 UNC designation is one of the most widely used coarse-thread sizes in general mechanical and structural assembly, making this die a standard shop tool across HVAC, plumbing, electrical, and industrial maintenance trades.

Installation Notes

Round dies are installed by machinists or maintenance mechanics using a matching die stock holder. Secure the die in the stock with the center screw seated in the die adjustment slot before use. Apply cutting oil to the workpiece and die before threading to extend tool life and improve thread quality. Inspect the die for chipping or wear before each use and replace if thread form appears degraded.
