Frequently Asked Questions

What is the CHICAGO-LATROBE Spiral Point Tap M16x2 used for?

This tap is used for cutting internal metric threads in through-hole applications. The spiral-point design pushes chips ahead, making it ideal for production tapping in steel, aluminum, and alloys. It is commonly used in automotive, aerospace, and general manufacturing where precise M16x2 threads are required.

What are the specifications of the CHICAGO-LATROBE 313524 tap?

This is an oversized spiral-point tap with M16x2 metric thread, D11 / 6H tolerance, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) and has a manufacturer part number 313524. The D11 / 6H designation indicates an oversized thread for use after coating or plating.

How to select the correct CHICAGO-LATROBE tap for M16x2 threads?
