Frequently Asked Questions

What is an OSG spiral-flute STI tap used for?

An OSG spiral-flute STI tap is used to cut internal threads in steel and stainless steel for screw thread inserts. It creates threads that accept helical coil inserts, providing stronger, wear-resistant threads in softer materials like aluminum or cast iron.

What are the specifications of the OSG STI tap 30204808?

The OSG STI tap model 30204808 has a thread size of 3/4"-16 UNF, a thread tolerance of H3 / 2B-3B, and a 4-flute spiral-flute design. It is designed for tapping steel and stainless steel for screw thread inserts.
