  • Three flutes clear chips efficiently for clean threads
  • 85mm overall length reaches deep workpieces

Straight Flute Hand Tap M16x2 HSS

This straight flute hand tap creates M16x2 metric threads in through holes. The high-speed steel body with black oxide finish resists wear during manual or machine tapping. Overall length is 96.85 mm with a 46.05 mm thread length and three flutes for chip evacuation. It meets class 6H fit with a D11 thread limit.

Suited for M16x2 through holes only

The plug chamfer starts threads easily in through holes but does not reach full depth in blind holes. Builders who need bottoming taps for blind holes or a different thread pitch should look elsewhere. The 14.00 mm drill size suits 75 percent thread engagement in standard materials.

Thread limit D11 class 6H fit

The D11 limit controls the pitch diameter tolerance for a 6H class of fit on M16x2 threads. This single specification determines whether the tap matches the required hole tolerance for the application. Verify the class of fit before ordering.

Questions about this item

How can I confirm the M16x2 tap is cutting correctly after setup?

Verify the thread pitch measures 2 mm and the major diameter reaches 16 mm using a thread gauge; the finished thread should match the 6H class of fit.

What comes in the package and what must I supply separately?

The box contains the CHICAGO-LATROBE 313579 straight-flute hand tap only; you must provide a 14.00 mm drill bit for the 75 percent thread drill size and a tap wrench.

Which version of this M16x2 tap should I choose for a standard fit?

Select the D11 thread limit with 6H class of fit, 3 flutes, 96.85 mm overall length and 46.05 mm thread length for general-purpose metric threading.
