Osg 2711600 Round Die 5/8-18 Unf 2 Inch Od High Speed Steel

Product Description

The OSG 2711600 is a round threading die designed to cut external 5/8-18 UNF right-hand threads on iron and steel workpieces. Built from high-speed steel (HSS), this die maintains cutting edge hardness through the heat generated during threading operations. It measures 2 inches in outside diameter and 5/8 inch in thickness, fitting standard 2-inch OD die stocks. The adjustable design allows the operator to fine-tune thread fit by opening or closing the die slightly using the die stock adjustment screws. At 0.4 pounds, it is a compact and durable tool suited for production threading or repair work in machine shops, maintenance facilities, and industrial trades.

This die is intended for threading mild steel and iron fasteners, rods, and fittings in applications requiring a 5/8-18 UNF thread form. The UNF (Unified National Fine) thread standard is common in automotive, hydraulic, and precision mechanical assemblies where a finer thread pitch provides greater thread engagement strength and vibration resistance compared to coarse-thread equivalents. It is used by machinists, maintenance technicians, and pipe or fitting fabricators who need reliable, repeatable external threads on ferrous materials.

Key Features

• 5/8-18 UNF right-hand thread form for fine-pitch external threading
• High-speed steel construction for heat resistance and edge retention during threading
• 2 inch outside diameter fits standard 2-inch OD die stocks and holders
• Adjustable design allows thread fit fine-tuning without changing the die
• Rated for use on iron and steel workpieces
• OSG Series 134 designation for cross-reference and replacement sourcing

Compatibility

Designed for use on iron and steel workpieces requiring a 5/8-18 UNF right-hand external thread. Fits die stocks and holders accepting a 2-inch OD round die.

Installation Notes

This die should be mounted securely in a properly sized 2-inch OD die stock before use. Ensure the workpiece is clamped or fixtured to prevent rotation during threading. Apply an appropriate cutting fluid for ferrous metals to extend die life and produce cleaner thread forms. Inspect the die for wear or chipping before each use and replace if cutting edges are damaged.
