Balax 12203-000 Thread Forming Tap 10-32 Unf Plug Hss

Product Description

The BALAX 12203-000 is a thread forming tap designed for producing 10-32 UNF internal threads in ductile materials without cutting chips. Unlike cutting taps, this plug-style forming tap displaces material to create threads, resulting in stronger thread forms and eliminating chip removal concerns in blind and through-hole applications. Manufactured from high-speed steel with a bright uncoated finish, the 12203-000 carries a Class 3B fit and an H3 thread limit, making it suitable for precision threading work where tight tolerances are required. Overall length is 2.375 inches with a thread length of 0.600 inches.

This tap is used in through-hole threading operations on ferrous and non-ferrous metals, plastics, and other formable materials. The plug chamfer, with 4 chamfered threads, allows for easy starting in a pre-drilled hole and is well suited for production environments and maintenance shops alike. It is a standard choice for machinists, tool and die workers, and maintenance technicians threading 10-32 UNF fastener holes in light fixtures, electronic enclosures, and mechanical assemblies.

Key Features

• Thread forming design eliminates chips, reducing tap breakage risk and cleanup in through-hole applications
• 10-32 UNF thread form with Class 3B fit and H3 thread limit for precision tolerance control
• Plug chamfer with 4 chamfered threads for reliable hole entry and alignment
• High-speed steel construction provides durability across repeated use in production settings
• Bright uncoated finish suitable for use with standard tapping oils and coolants
• Single oil groove aids lubrication distribution during the forming process

Compatibility

Designed as a direct-fit thread forming tap for through-hole 10-32 UNF applications in the BXP series. Intended for use with standard tap wrenches, T-handle holders, or machine tapping setups configured for 10-32 UNF tooling.

Installation Notes

Thread forming taps require a properly sized forming tap drill hole, which is typically larger than the equivalent cutting tap drill size - consult a thread forming drill chart before drilling. Apply tapping fluid or cutting oil appropriate for the workpiece material before use. Secure the workpiece fully before tapping to prevent movement. For machine tapping, verify spindle speed and feed rate are set for form tapping to avoid tap breakage.
