OSG Spiral-Flute STI Taps for Nickel & Titanium.

Frequently Asked Questions

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

An OSG Screw Thread Insert STI Tap is used to cut internal threads for helical wire inserts in nickel and titanium alloys. Its spiral-flute design evacuates chips effectively, making it ideal for aerospace, automotive, and high-temperature industrial applications where thread strength and reliability are critical.

What are the specifications of the OSG STI Tap 7/16"-20 UNF?

This OSG STI Tap has a 7/16"-20 UNF thread size, H4 / 2B-3B tolerance, and 3 flutes. It is designed for screw thread insert (STI) applications in nickel and titanium alloys. The spiral-flute geometry aids chip evacuation in deep or blind holes, ensuring clean, accurate threads.

Where to buy OSG STI Taps for nickel and titanium worldwide?

3G Electric supplies OSG STI Taps, including the 7/16"-20 UNF model, to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this and other OSG cutting tools for demanding materials.

How to select the correct STI tap for nickel alloys?

Select an STI tap with spiral flutes for nickel alloys to manage chip evacuation and reduce torque. Ensure the tap size matches the insert thread (e.g., 7/16"-20 UNF) and tolerance (H4 for 2B-3B fit). Use appropriate cutting fluid and rigid tapping equipment to prevent work hardening and tool breakage.
