Osg 1010102 Straight Flute Tap 0-80 Unf Plug 2B Hss

Product Description

The OSG 1010102 is a straight flute plug tap designed for cutting 0-80 UNF internal threads in a wide range of ferrous and non-ferrous materials. It features 2 flutes and a plug chamfer, which provides a gradual thread lead-in suited for through-hole tapping applications. Manufactured from high-speed steel, it delivers reliable wear resistance in production and maintenance environments. The H2 thread limit ensures dimensional accuracy within standard 2B class of fit tolerances. With an overall length of 1.625 inches and a thread length of 0.3125 inches, this tap is sized for small-fastener work common in precision machining and assembly.

This tap is appropriate for use in manual tapping, drill press, and machine tapping operations where 0-80 UNF threads are required. Compatible material applications include aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It is commonly used by machinists, tool and die makers, maintenance technicians, and precision assembly professionals working with miniature fastener sizes in both production and repair settings.

Key Features

• Compact 1.625-inch overall length sized for small-part and confined-space tapping

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring a 0-80 UNF straight flute plug tap with a 2B class of fit. Compatible workpiece materials include aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel per manufacturer specification.

Installation Notes

This tap should be installed and used by qualified machinists or maintenance technicians familiar with thread-cutting operations. Always secure the workpiece and use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Ensure the tap is properly aligned with the pilot hole before applying torque to avoid tap breakage, which is a particular risk at this miniature size. Follow applicable shop safety protocols and refer to manufacturer feed and speed recommendations for the specific material and machine setup.
