Frequently Asked Questions

What is the OSG Screw Thread Insert STI Tap used for?

This OSG spiral-flute STI tap is designed for cutting internal threads in nickel and titanium alloys. It is commonly used in aerospace, automotive, and industrial applications where high-strength, corrosion-resistant threaded inserts are required. The 3-flute design aids chip evacuation in deep-hole threading.

What are the specifications of the OSG 31520608 STI tap?

The OSG 31520608 is a spiral-flute STI tap with thread size 1/4"-28 UNF, tolerance H3 / 2B-3B, and 3 flutes. It is engineered for threading in nickel and titanium alloys. The H3 tolerance ensures precise fit for screw thread inserts, while the spiral flute design improves chip removal during operation.

How to select the correct OSG STI tap for nickel alloys?

For nickel alloys, choose an STI tap with spiral flute design and appropriate thread tolerance, such as the OSG 31520608 with H3 / 2B-3B. Ensure the tap matches the insert thread size (e.g., 1/4"-28 UNF). Use proper cutting fluid and reduce speed to prevent work hardening. Consult OSG's technical data for feed rates.
