Frequently Asked Questions

What is the OSG spiral flute tap #8-32 UNC used for?

This OSG spiral flute tap is designed for threading blind holes in steel and stainless steel. Its spiral flute design evacuates chips upward, preventing clogging, while the modified bottoming chamfer allows threading close to the hole bottom. It is ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG spiral flute tap 1754708?

The OSG spiral flute tap (MPN 1754708) has a #8-32 UNC thread size, H4 / 2B-3B tolerance, 2 flutes, and a modified bottoming chamfer. It is designed for threading steel and stainless steel. The H4 tolerance ensures precise fit for class 2B or 3B internal threads.

How to select the right OSG tap for stainless steel?
