Hertel K020345AS M16 X 2.00 Straight Flute Tap Hss Plug

Product Description

The HERTEL K020345AS is a straight flute tap designed for cutting M16 x 2.00 metric coarse internal threads in a plug chamfer style. Built from high speed steel (HSS) with a bright, uncoated finish, this tap handles through-hole and blind-hole threading applications in ferrous and non-ferrous materials. It features 4 flutes with a right-hand thread direction and a D4 thread limit, which provides a tighter tolerance range suited to general-purpose threading. With an overall length of 3.813 inches and a thread length of 1.813 inches, the K020345AS fits standard tap holders and T-handle wrenches used in machining and maintenance environments.

This tap is suited for job shop machining, maintenance and repair operations (MRO), and production threading where M16 metric coarse threads are required. The plug chamfer style makes it effective as a starting tap for most through-hole applications and adaptable to shallow blind holes when paired with a bottoming tap. It is commonly used by machinists, tool and die technicians, and maintenance mechanics working with metric fastener specifications.

Key Features

• M16 x 2.00 metric coarse thread specification for standard metric fastener compatibility
• Plug chamfer for versatile use in through-holes and moderate-depth blind holes
• High speed steel construction provides durability across a range of workpiece materials
• 4 straight flutes suitable for shorter chip materials and through-hole threading
• D4 thread limit for controlled tolerance fit in general-purpose applications
• Right-hand thread direction, standard for most threading operations

Compatibility

Designed as a standard M16 x 2.00 metric coarse plug tap compatible with tap holders, T-handle wrenches, and tapping heads sized for a 0.480-inch shank diameter and a 0.360-inch square drive.

Installation Notes

Tapping operations should be performed by qualified machinists or maintenance mechanics following standard threading procedures. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the drilled hole before applying torque. Use an appropriate cutting fluid for the workpiece material to reduce tool wear and improve thread quality. Inspect the tap for wear or chipping before each use, and never reverse a broken tap without proper extraction tooling.
