Hertel K010330AS Thread Forming Tap 6-32 Unc Plug Hss

Product Description

The HERTEL K010330AS is a thread forming tap designed for creating 6-32 UNC internal threads in ductile materials without cutting or removing material. Unlike cutting taps, this plug-style forming tap displaces metal to generate threads, producing a stronger finished thread with no chips to clear. Made from high-speed steel with a bright uncoated finish, it is suited for through-hole threading applications in soft metals and plastics. The tap features an H3 thread limit for controlled tolerance and a right-hand thread direction. With a 2.0 inch overall length and a 0.6875 inch thread length, it fits standard tap handles and machines used in light industrial and maintenance applications.

This tap is used in through-hole threading operations where chip-free thread formation is required. It is well suited for residential and commercial maintenance, electrical enclosure assembly, HVAC cabinet fabrication, and general metalworking where 6-32 UNC fastener threads are common. The plug chamfer with 3 to 5 chamfered threads allows the tap to start easily in a pre-drilled hole. A licensed machinist or skilled tradesperson typically installs this tap by hand or with a machine in applications requiring consistent, repeatable 6-32 thread production.

Key Features

• Thread forming design displaces material rather than cutting, producing stronger threads with no chips
• 6-32 UNC thread size with 2B class of fit for standard fastener compatibility
• Plug chamfer (3-5 chamfered threads) for easy starting in through-holes
• H3 thread limit for consistent tolerance control
• High-speed steel construction provides wear resistance for repeat use
• Right-hand thread direction, suitable for standard tap handles and tapping machines

Compatibility

Designed as a standard 6-32 UNC plug-style thread forming tap compatible with through-hole applications in ductile metals and soft materials where chip-free thread generation is required.

Installation Notes

This tap is installed by machinists or skilled tradespeople using a standard tap handle or tapping machine. Always drill the correct tap drill size for thread forming before use, as forming taps require a slightly larger pilot hole than cutting taps for the same thread size. Ensure the workpiece is securely fixtured and apply appropriate tapping fluid to extend tool life and improve thread quality. Do not reverse the tap forcefully if resistance is encountered, as this may damage the tool or workpiece threads.
