Import BDNA-20720 Straight Flute Tap 10-24 Unc Hss

Product Description

The IMPORT BDNA-20720 is a straight flute tap designed to cut 10-24 UNC internal threads in a wide range of materials. Built from high-speed steel (HSS) with a gold oxide coating, this tap resists wear and handles moderate heat generated during threading operations. The taper chamfer eases entry into the workpiece, making thread starting more controlled and reducing the chance of tap breakage. Four flutes provide adequate chip clearance for most through-hole and blind-hole applications in ferrous and non-ferrous metals. The H3 thread limit maintains close tolerance fits suitable for standard fastener engagement.

This tap is intended for use in production and maintenance environments where 10-24 UNC threads are required. Typical applications include threading holes in sheet metal, mild steel, aluminum, brass, and plastic components. It is well-suited for machine tapping or careful hand tapping operations on assemblies in HVAC equipment, electrical enclosures, plumbing fixtures, and general mechanical fabrication. Machinists, maintenance technicians, and tradespeople performing field repairs will find this tap appropriate for standard 10-24 fastener installation work.

Key Features

• 10-24 UNC thread form for standard inch-series fastener compatibility
• Taper chamfer for controlled thread entry and reduced breakage risk
• High-speed steel construction provides durability across common workpiece materials
• Gold oxide coating improves lubricity and corrosion resistance during use
• H3 thread limit ensures consistent tolerance for standard fit fasteners
• 4-flute design promotes chip evacuation in typical threading operations

Compatibility

Designed for cutting 10-24 UNC right-hand internal threads in standard tapping applications across ferrous metals, non-ferrous metals, and plastics.

Installation Notes

This tap should be installed in a compatible tap wrench or machine tap holder rated for the tap shank size. Always apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread finish. Ensure the workpiece is securely fixtured before beginning the threading operation. Follow standard shop safety practices and discard worn or chipped taps immediately to prevent breakage in the workpiece.
