Import BDNA-20702 Straight Flute Tap 6-32 Unc Hss

Product Description

The IMPORT BDNA-20702 is a straight flute tap designed for cutting 6-32 UNC internal threads in a wide range of materials. Built from high-speed steel (HSS) with a gold oxide finish, this tap provides good wear resistance and reduces friction during the threading process. It features a plug chamfer, which makes it suitable for through-holes and for starting threads with moderate lead-in. The overall length is 2 inches, and the right-hand, H3 thread limit designation ensures consistent fit within standard tolerance classes. Machinists, maintenance technicians, and toolroom professionals rely on this type of tap for precision thread cutting in production and repair applications.

This tap is used in metalworking, fabrication, and maintenance settings where 6-32 UNC machine screw threads are required. The 6-32 size is commonly encountered in light-duty fastener applications including electrical enclosures, electronics, and small mechanical assemblies. The plug chamfer style is appropriate for most general threading operations where the tap can pass fully through the workpiece or where thread engagement begins away from the bottom of a blind hole.

Key Features

• 6-32 UNC thread form with 32 threads per inch for standard machine screw compatibility
• Plug chamfer provides moderate lead-in, suitable for through-holes and general-purpose tapping
• High-speed steel (HSS) construction offers durability across a range of workpiece materials
• Gold oxide finish reduces friction and provides mild corrosion resistance
• H3 thread limit designation ensures consistent tolerance for standard 6-32 fastener fit
• Right-hand thread direction for standard tapping operations

Compatibility

Designed for use in any application requiring 6-32 UNC right-hand internal threads. Compatible with standard 6-32 tap handles, T-handle wrenches, and machine tool tap chucks designed for this thread and shank size.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap handle, tap wrench, or machine spindle. Secure the workpiece before tapping and use an appropriate cutting fluid to extend tool life and improve thread quality. Advance the tap slowly and back off periodically to break chips and clear the flutes. Inspect the tap for wear or breakage before each use, as a damaged tap can permanently damage the workpiece.
