  • M16x1.5 metric threads for precise fastening

  • Three flutes clear chips efficiently for smoother cutting
  • Bright uncoated finish suits general-purpose threading tasks

M16x1.5 Straight Flute Hand Tap

This M16x1.5 straight flute hand tap is designed for creating internal threads in a workshop or maintenance setting. It suits mechanics and fabricators who need to cut metric threads by hand with a semi-bottoming chamfer. The D11 thread limit targets a 6H class of fit for general-purpose fastening.

High Speed Steel construction and uncoated finish

The tap is made from high speed steel with a bright uncoated surface for standard tapping tasks. Three flutes provide chip clearance during manual operation. Right-hand thread direction matches common fastener requirements for through or blind holes.

Thread size M16x1.5 with 14.00 mm drill size

The defining specification is the M16x1.5 thread size paired with a 75 percent thread drill size of 14.00 mm. Buyers needing a different pitch diameter or a larger drill size for deeper engagement cannot use this tap.

Questions about this item

How do I install the M16x1.5 tap in a tap wrench, and what step is often missed?

Clamp the square shank firmly in a suitable tap wrench, apply cutting fluid, and start the tap perpendicular to the workpiece. The step often missed is using the correct 14.00 mm drill size for the 75 percent thread depth before tapping.

What maintenance or replacement will the M16x1.5 hand tap need after repeated use?

The high-speed steel cutting edges will dull over time. Inspect the three flutes for wear or chipping after each job. Replace the tap when threads cut become oversized or the tool requires excessive force to start the M16x1.5 thread.

What limit appears first when tapping M16x1.5 holes continuously in steel?

Heat buildup in the high-speed steel body and cutting edges is the first limit during sustained use. The bright uncoated finish offers no thermal barrier, so cutting fluid must be reapplied frequently to prevent premature wear on the semi-bottoming chamfer.
