Import BDNA-20796 Straight Flute Tap 1-12 Unf 4 Flutes

Product Description

The IMPORT BDNA-20796 is a straight flute tap designed for cutting 1-12 UNF internal threads in metalworking and mechanical assembly applications. With 4 flutes and a Gold/Oxide coating, this tap delivers consistent thread formation in through-hole and blind-hole configurations. The H4 thread limit designation indicates a tolerance class suited for close-fit threading where dimensional control is required. Right-hand thread direction is standard for conventional fastener work. This tool is typically used by machinists, maintenance technicians, and trade professionals performing threading operations in metal components across industrial and mechanical service environments.

The BDNA-20796 is suited for tapping 1-12 UNF threads in ferrous and non-ferrous metals in shop, field, or maintenance settings. The 1-12 UNF thread size is a unified fine-pitch thread commonly used in precision mechanical assemblies where vibration resistance and fine adjustment are critical. The Gold/Oxide finish provides a degree of lubricity and corrosion resistance that extends tool life during moderate-duty threading operations. Sold individually, this tap is appropriate for both bench work and in-situ repairs requiring a single unit.

Key Features

• 1-12 UNF thread size for unified fine-pitch threading applications
• 4-flute straight flute geometry for controlled chip management in through and blind holes
• Gold/Oxide coating improves lubricity and extends tool life
• H4 thread limit for precision close-fit tolerance control
• Right-hand thread direction for standard fastener compatibility

Compatibility

Designed for cutting 1-12 UNF internal threads; compatible with standard tap wrenches and machine tap holders accepting the appropriate shank size for this thread class.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using manual tap wrenches or machine threading equipment. Always ensure the workpiece is securely clamped and the correct tap drill size for 1-12 UNF is used before threading. Apply appropriate cutting fluid to reduce heat and friction during the tapping operation. Inspect the tap for wear or chipping before each use to avoid thread damage or breakage.
