Frequently Asked Questions

What is the OSG spiral flute tap 1704301 used for?

The OSG spiral flute tap 1704301 is designed for threading blind holes in steel and stainless steel.

It is ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG spiral flute tap 3/8-16 UNC?

This OSG tap has a 3/8-16 UNC thread, H5 tolerance for 2B-3B class fit, 3 flutes, and a modified bottoming chamfer. The spiral flute design is optimized for steel and stainless steel. The manufacturer part number is 1704301. 3G Electric supplies this genuine OSG tap for industrial threading operations.
