Balax 13825-000 Thread Forming Tap 7/16-14 Unc Plug Hss

Product Description

The BALAX 13825-000 is a thread forming tap in the BXP series, designed for through-hole threading applications in metalworking and fabrication environments. It cuts a 7/16-14 UNC right-hand thread using a plug chamfer with 4 chamfered threads for controlled entry. Manufactured from high-speed steel with a bright uncoated finish, this tap operates without coolant-through capability and is rated at an H5 thread limit for close-tolerance work. Overall length is 3.156 inches with a thread length of 0.950 inches. Licensed machinists, millwrights, and maintenance technicians are the primary installers.

This tap is suited for through-hole threading in ferrous and non-ferrous materials where a formed thread profile is preferred over a cut thread. The plug chamfer design makes it appropriate for applications where the tap can pass fully through the workpiece. Its 0.323-inch shank diameter and 0.242-inch square drive size fit standard tap wrenches and machine holders used in production and job-shop settings. The H5 thread limit keeps finished threads within tight tolerance bands required for precision assemblies.

Key Features

• 7/16-14 UNC thread size with right-hand direction for standard fastener compatibility
• Plug chamfer with 4 chamfered threads for guided entry in through-hole applications
• High-speed steel construction provides wear resistance across a range of workpiece materials
• H5 thread limit maintains close-tolerance thread form for precision fit requirements
• BXP series design with 1 oil groove supports lubrication flow during the forming process
• Bright uncoated finish allows direct inspection of tool condition and wear

Compatibility

Designed as a direct-fit thread forming tap for through-hole applications requiring a 7/16-14 UNC thread form in standard tap wrench and machine holder setups accepting a 0.323-inch shank diameter.

Installation Notes

Thread forming taps are installed by qualified machinists or maintenance technicians using a calibrated tap wrench, tapping head, or CNC machine holder. Secure the workpiece firmly and ensure the tap enters the hole square to the axis to avoid tap breakage or thread misalignment. Apply an appropriate cutting or forming fluid to reduce friction and extend tool life. Disconnect power to any powered equipment before performing manual tapping operations in a live machine.
