Recoilscrew threads inserts are used to produce new threads or can be used to repair threaded holes which have been damaged or stripped and refurnish them to their original thread size. The Recoil insert, which is larger in diameter than the tapped hole is compressed during installation then allowed go spring back, permanently anchoring the

Clutch Themain physical differences between NPT and NPTF are the flatness of the peaks and valleys of the threads. For the sake of our NPT tap drill chart, you simply need to know the distinction between an NPT fitting and NPTF. For example, reading across you’ll find that a 1/8 NPT tap will require an “R” size tap drill.

NPT pipe threads are the most common pipe thread used in the USA.

Forexample, if you have a 1/8” NPT pipe tap, the R type is the appropriate drill bit to use with this tap. If the pipe tap is tapered, the ideal drill size is 21/64mm in fraction form or 0.339”. For non-tapered or straight pipe taps, use a drill size of 11/32mm or 0.344”. This delivers 27 threads per inch.
