Spiral Flute Tap 5/16 -24 HSS MPN:313583

Oversized taps have a slightly larger pitch diameter than standard taps. They are used to make threads in a hole before a coating or treatment is applied to the hole. Once the coating or treatment is applied, the threads will be reduced to the standard pitch diameter. The black-oxide finish on these taps retains lubricants to improve the taps' wear resistance and chip flow. Black-oxide taps should only be used on ferrous metals.
