Hertel K020361AS Straight Flute Tap M16 X 1.50 Hss Plug

Product Description

The HERTEL K020361AS is a straight flute plug tap ground to Metric Fine thread standards for cutting internal M16 x 1.50 threads. It features four flutes, a plug chamfer for general-purpose through-hole and blind-hole tapping, and is manufactured from high speed steel with a bright uncoated finish. The overall length is 3.8125 inches with a thread length of 1.8125 inches. The shank diameter measures 0.4800 inches and the square drive size is 0.3600 inches. This tap is designed for use with a standard tap wrench or machine tapping setup and is suited for threading operations in ferrous and non-ferrous materials.

This tap is intended for machinists, tool and die makers, and maintenance technicians working with Metric Fine thread specifications. The M16 x 1.50 thread size is commonly used in automotive, precision machinery, and general mechanical assemblies where a finer thread pitch than the coarse M16 x 2.00 standard is required. The plug chamfer style provides a lead-in of 3 to 5 threads, making it suitable for both starting a thread and completing it in through-hole applications. The right-hand thread direction aligns with standard fastener conventions.

Key Features

• M16 x 1.50 Metric Fine thread form for precision thread cutting
• Plug chamfer with 3 to 5 thread lead-in for through-hole and blind-hole use
• Four straight flutes for chip clearance in shorter-chipping materials
• High speed steel construction for durability across common workpiece materials
• Bright uncoated finish suitable for use with cutting fluids
• Right-hand thread direction, D3 thread limit for standard tolerance fits

Compatibility

Designed as a standard replacement or production tap for any application requiring a right-hand M16 x 1.50 Metric Fine internal thread. Compatible with tap wrenches and machine tool holders accepting a 0.4800 inch shank diameter with a 0.3600 inch square drive.

Installation Notes

Secure the workpiece and ensure the correct tap drill size for M16 x 1.50 is used prior to tapping. Apply a suitable cutting fluid to reduce heat and extend tool life, particularly when tapping steel or harder alloys. Use a tap wrench for hand tapping or confirm spindle speed and feed rate settings before machine tapping. Inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.
