Balax 11622-010 Thread Forming Tap 8-32 Unc Bottoming Hss

Product Description

The BALAX 11622-010 is a thread forming tap designed for creating 8-32 UNC internal threads in blind hole applications. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap features a bottoming chamfer with 2.5 chamfered threads, allowing threads to be formed close to the bottom of a blind hole. Manufactured from high-speed steel with a bright uncoated finish, the 11622-010 carries a Thread Limit of H2 and is suited for use in ductile metals. It is installed by machinists, tool and die professionals, and maintenance technicians working on threaded fastener applications.

This tap is intended for blind hole threading in production and repair environments where chip-free thread forming is preferred. The bottoming chamfer style makes it well suited for applications requiring full threads as close to the bottom of a hole as possible. The BXB series design supports use with tapping fluids or cutting oils appropriate for the workpiece material. Right-hand thread direction matches standard 8-32 UNC fastener conventions used across industrial, electrical, and mechanical assemblies.

Key Features

• Thread forming design displaces material for stronger, chip-free threads
• Bottoming chamfer with 2.5 chamfered threads for threading close to hole bottom
• High-speed steel construction for durability across ductile metal applications
• H2 thread limit for controlled thread tolerance
• Right-hand thread direction, 8-32 UNC standard
• Single oil groove to support lubrication during forming

Compatibility

Designed for blind hole threading applications requiring 8-32 UNC right-hand threads in ductile materials compatible with thread forming operations.

Installation Notes

Thread forming taps require a specific tap drill size larger than those used for cutting taps - consult a thread forming drill chart for the correct hole diameter before tapping. Secure the workpiece and use a calibrated tap handle or machine tapping setup to maintain proper alignment. Apply an appropriate tapping fluid or cutting oil for the workpiece material to reduce forming force and extend tap life. Do not use thread forming taps in brittle materials such as cast iron or hardened steel.
