Cleveland C54803 M16x2.00 Bottoming Hand Tap Hss 4-flute

Product Description

The CLEVELAND C54803 is a bottoming hand tap designed for cutting M16x2.00 metric coarse threads in both blind holes and through-holes. Built from high speed steel with a bright uncoated finish, this 4-flute straight flute tap delivers clean thread formation in a range of ferrous and non-ferrous materials. The bottoming chamfer allows threading close to the bottom of a blind hole, making it the right choice when full thread depth near a stopped bore is required. Overall length is 3.813 inches with a thread length of 1.81 inches. It carries a 6H class of fit and a D7 thread limit, suitable for standard tolerance threading applications in production and toolroom environments.

This tap is suited for use in machine shops, maintenance facilities, and fabrication environments where metric fastener threads must be cut or restored. The M16x2.00 size is a common metric coarse thread used in structural fastening, machinery frames, and equipment assemblies. It is appropriate for blind hole threading where chamfer length matters and for through-hole applications requiring a clean, full-depth thread profile. Machinists and tool and die technicians are the typical end users.

Compatibility

Designed for cutting M16x2.00 metric coarse threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces, in both blind hole and through-hole configurations.

Installation Notes

This tap is intended for use by qualified machinists and tool technicians. Secure the workpiece and use a properly aligned tap wrench or tapping fixture to avoid tap breakage from misalignment. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Never force a tap past resistance, as high speed steel taps are brittle and will break under torsional overload.
