Tap Bottom Carbon Steel ISO Coarse M4 x 0.7

Sutton Tools Carbon Hand Taps are ideal for routine maintenance, repair work and for rethreading where high accuracy and tolerance thread is not critical. Straight flutes are designed for tapping into materials where chips break-up readily and present no disposal problems, particularly in through-hole tapping. Straight flute taps are only suitable for hand operations, tapping up to 1-1/2 x diameter.
