Balax 13805-000 Thread Forming Tap 7/16-14 Unc Bottoming Hss

Product Description

The BALAX 13805-000 is a thread forming tap designed for cutting 7/16-14 UNC internal threads in blind hole applications. Unlike cutting taps, thread forming taps displace material rather than remove it, producing stronger threads with no chips to clear. This tap is made from high-speed steel with a bright uncoated finish and features a bottoming chamfer with 2.5 chamfered threads, allowing it to thread close to the bottom of a blind hole. The H5 thread limit designation indicates a controlled tolerance for consistent thread fit. It is installed by machinists, tool and die workers, and maintenance technicians working with steel, aluminum, and similar machinable materials.

The BALAX 13805-000 is suited for blind hole threading operations in production and maintenance environments. The bottoming chamfer makes it the correct choice when threads must extend as deep as possible in a stopped bore. It is part of the BXB series and is intended for use in machine tapping applications where torque is applied through a tap holder or tapping head. Right-hand thread direction is standard for conventional UNC fastener engagement. One oil groove aids lubrication during the forming process.

Key Features

• 7/16-14 UNC thread size with right-hand thread direction
• Bottoming chamfer with 2.5 chamfered threads for near-bottom thread forming in blind holes
• High-speed steel construction for durability across a range of workpiece materials
• H5 thread limit for controlled tolerance and consistent thread fit
• Bright uncoated finish suitable for use with cutting oils and tapping fluids
• One oil groove for lubrication flow during thread forming

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for blind hole threading operations requiring 7/16-14 UNC threads in the BXB series.

Installation Notes

Thread forming taps should be installed by qualified machinists or maintenance technicians familiar with tapping torque requirements for the specific workpiece material. Always use a recommended tapping fluid or cutting oil to reduce friction and extend tap life. Secure the workpiece and ensure the tap is properly aligned before beginning the forming operation to avoid tap breakage. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting spindle speed and feed rate.
