Osg 2706800 Round Threading Die 3/8-16 Unc 1.5 in Hss

Product Description

The OSG 2706800 is a round threading die designed to cut external threads on iron and steel workpieces. It produces 3/8-16 UNC right-hand threads and features an adjustable design that allows the operator to fine-tune thread fit and compensate for wear. The die is manufactured from high-speed steel (HSS), which provides the hardness and heat resistance required for threading ferrous materials in production and maintenance environments. At 1.5 inches in outside diameter and 0.5 inches thick, it fits standard round die stocks of the same OD. Machinists, pipefitters, and maintenance mechanics are the primary users of this type of tooling.

This die is suited for threading bolts, studs, and rod stock in both shop and field applications. The 3/8-16 UNC specification is one of the most common unified coarse thread sizes used in general mechanical assemblies, structural fastening, and equipment repair across manufacturing, HVAC, plumbing, and industrial maintenance trades. The adjustable feature makes it practical for both new thread cutting and chasing damaged threads. It is supplied individually and is compatible with standard 1.5-inch round die holders and die stocks.

Installation Notes

This die is installed into a matching 1.5-inch round die stock before use. Secure the die in the holder using the set screws provided on the die stock before beginning any threading operation. Apply appropriate cutting oil to the workpiece and die to reduce friction, prevent galling, and extend tool life. Inspect the die for chips or damage before each use, and adjust the adjusting screw to the desired thread fit prior to cutting.
