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

Match the tap thread size (M16x1.5) and tolerance class (6H) to your hole requirements. For through holes, a spiral point tap with plug chamfer is ideal. The D11 oversized variant is used when a slightly larger thread is needed. Always verify material compatibility and use proper cutting fluid.
