Osg 2727800 Round Threading Die 8-36 Unf High Speed Steel

Product Description

The OSG 2727800 is a round threading die designed to cut external threads on ferrous workpieces including iron and steel. Built from high-speed steel, this die handles the demands of repeated use in production and maintenance environments. It cuts a right-hand 8-36 UNF thread profile and features an adjustable design that allows minor diameter compensation for fit and wear tolerance. The outside diameter measures 0.8125 inches with a thickness of 0.25 inches, fitting standard round die stocks for that OD. Licensed machinists, toolmakers, and maintenance mechanics are the primary users.

This die is suited for threading small-diameter fasteners, machine screws, and precision components in light manufacturing, tool and die, and general maintenance applications. The 8-36 UNF designation means 36 threads per inch on a Number 8 major diameter, a fine-pitch thread common in instrument assemblies, electronics hardware, and precision mechanical assemblies where vibration resistance and fine adjustment are required. It is intended for manual or bench-mounted die stock use.

Key Features

• High-speed steel construction for durability across iron and steel workpieces
• Adjustable die body allows compensation for diameter variation and die wear
• Right-hand thread direction, 8-36 UNF specification
• Outside diameter of 0.8125 inches fits standard round die stocks
• Thickness of 0.25 inches for stable seating in die stock
• Series 134 designation for consistent OSG tooling family fitment

Compatibility

Designed for use on iron and steel workpieces. Fits round die stocks sized for a 0.8125-inch outside diameter. Intended for 8-36 UNF external thread cutting applications.

Installation Notes

This die is installed and operated by machinists or maintenance mechanics using a compatible round die stock. Secure the workpiece firmly before threading to prevent movement and ensure thread straightness. Apply cutting oil to the die and workpiece before starting to extend die life and improve thread finish. The adjustable feature should be set before threading begins; do not attempt to adjust the die mid-cut.
