Osg 2707000 Round Threading Die 7/16-14 Unc Hss

Product Description

The OSG 2707000 is a round threading die used to cut external threads on iron and steel workpieces. It produces a 7/16-14 UNC right-hand thread and is manufactured from high-speed steel (HSS) for durability under repeated use in production and maintenance environments. At 1.5 inches outside diameter and 0.5 inches thick, this die fits standard round die stocks and holders designed for that OD. The adjustable design allows the operator to fine-tune thread fit by closing or opening the die slightly before the final pass. Licensed machinists, tool and die technicians, pipefitters, and maintenance mechanics are the primary users.

This die is suited for threading bolts, studs, rod stock, and fastener blanks in shop and field applications. The 7/16-14 UNC designation is a coarse-thread standard common in structural fastening, machinery assembly, and general-purpose ironwork. It performs in manual die stocks as well as machine-held die heads where the OD and thickness match. Typical use cases include fabrication shops, maintenance and repair operations, and production lines that need replacement or additional threading tooling for common UNC sizes.

Compatibility

Designed for use on iron and steel workpieces requiring a 7/16-14 UNC right-hand external thread. Fits round die stocks and holders accepting a 1.5 inch outside diameter die.

Installation Notes

Round dies are installed and operated by machinists or qualified maintenance technicians using a properly sized die stock or holder. Ensure the workpiece is secured in a vise and that the die is seated squarely before beginning the threading pass to avoid cross-threading or taper. Apply an appropriate cutting oil to the workpiece and die throughout the operation to reduce heat and extend tool life. Inspect the die for chipping or wear before each use and replace if thread form quality degrades.
