  • TypeHole, Drill, Bore & Wire Gauges

  • Plug chamfer engages quickly for general-purpose threading
  • Four flutes clear chips efficiently while maintaining strength
  • Carbon steel construction handles routine tapping tasks
  • Right-hand threads suit standard fastening applications

Thread Size 1"-8 UNC

This Westward straight flute hand tap cuts internal threads with a 1"-8 UNC pitch using a plug chamfer and four flutes. It is made from carbon steel with a bright uncoated finish and is designed for right-hand threading in general-purpose applications. The tool measures 5 1/8 inches overall with a thread length of 2-1/2 inches.

Manual Thread Cutting Setup

The tap requires a properly sized drill hole and a suitable tap wrench for hand operation, neither of which are included. Cutting fluid should be applied during use to reduce friction and improve chip evacuation through the four flutes. This setup frees the user from needing powered tapping equipment for low-volume or repair work.

Mechanics and Maintenance Technicians

This tap suits professionals and hobbyists who need to create or repair 1"-8 UNC threads by hand in materials compatible with carbon steel tooling. It is not for buyers who need coated taps for extended life in abrasive alloys, spiral-flute designs for blind-hole chip removal, or powered tapping on CNC equipment.

  • Straight flute design starts threads cleanly in through-holes
