449T10 General Purpose Spiral-Flute Taps

$8.50

Bulk orders will be discounted, please contact us.

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 bright finish on these taps provides a smooth, polished surface.
