Import BDNA-20784 Straight Flute Tap 8-36 Unf 4 Flutes

Product Description

The IMPORT BDNA-20784 is a straight flute tap designed for cutting 8-36 UNF internal threads in a wide range of materials. With 4 flutes and a gold oxide coating, this tap delivers consistent thread form and surface protection during hand or machine tapping operations. The H2 thread limit ensures a standard fit tolerance suitable for most general-purpose fastener applications. It is sized for No. 8 threads at 36 threads per inch, making it a common choice for precision assemblies in metalworking, maintenance, and repair environments. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this type of tap.

This tap is suited for through-hole and blind-hole applications in ferrous and non-ferrous metals, plastics, and similar materials where a right-hand UNF thread is required. The straight flute geometry is best applied in materials that produce short, brittle chips, allowing chips to clear without packing in the flute. It is a single-piece consumable tool typically used in production shops, MRO facilities, and field maintenance settings.

Key Features

• 8-36 UNF thread size for No. 8 fine-pitch threading
• 4 straight flutes for chip clearance in short-chipping materials
• Gold oxide coating for corrosion resistance and reduced friction during cutting
• Right-hand thread direction, the standard for general fastener applications
• H2 thread limit for standard fit tolerance in most general-purpose assemblies

Compatibility

Designed as a general-purpose replacement or stock tap for 8-36 UNF threaded hole applications across metalworking, MRO, and maintenance operations.

Installation Notes

Machinists and maintenance technicians should use appropriate cutting fluid to extend tool life and improve thread finish. Secure the workpiece fully before tapping to prevent movement and thread misalignment. Apply steady, even pressure and back the tap out periodically to break and clear chips, especially in blind holes. Inspect the tap for wear or chipping before each use and replace when cutting torque increases noticeably.
