Osg 1045700 Straight Flute Tap 10-24 Unc Plug Hss

Product Description

The OSG 1045700 is a straight flute plug tap designed for cutting 10-24 UNC right-hand internal threads in a wide range of ferrous and non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, it delivers reliable performance in general-purpose tapping applications. The plug chamfer style provides a gradual thread lead-in, making it well suited for through-hole tapping where partial thread engagement at entry is acceptable. With an overall length of 2.375 inches and a thread length of 0.875 inches, this tap fits standard tap handles and machine tool holders used in production and maintenance environments. The H2 thread limit ensures consistent tolerance control for standard-fit threaded assemblies.

This tap is intended for use in manual hand-tapping operations and machine tapping setups in shops, maintenance facilities, and field service environments. It is compatible with materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The straight flute geometry makes it a practical choice for short-chipping materials where chip evacuation through the flute is not required. Machinists, tool and die technicians, and maintenance professionals will find this tap well suited for repair work and new fabrication across both production and job-shop settings.

Installation Notes

Install in a tap handle or appropriate machine tool holder before use. Power down or de-energize any machine tool before mounting or removing the tap. Apply appropriate cutting fluid for the workpiece material to extend tool life and reduce galling. Follow shop safety practices and applicable OSHA standards when operating tapping equipment.
