Frequently Asked Questions

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

An OSG Screw Thread Insert STI Tap cuts internal threads in multiple materials to accept helical wire thread inserts. It is commonly used in aerospace, automotive, and general manufacturing to repair or reinforce tapped holes in aluminum, steel, and cast iron.

What are the specifications of the OSG STI Tap 1/4"-28 UNF?

This OSG STI Tap has a 1/4"-28 UNF thread size, H3 / 2B-3B tolerance, and a spiral-flute design with 3 flutes. The spiral flute helps evacuate chips upward, making it suitable for blind-hole threading in multiple materials.

Where to buy OSG STI Taps worldwide?

3G Electric supplies OSG STI Taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing specialist across 14 industrial departments, we provide genuine OSG cutting tools and can quote for your specific thread insert tap requirements.

How to select the correct OSG STI Tap for thread inserts?

Select an OSG STI Tap based on the thread insert's size and class of fit. For a 1/4"-28 UNF insert, use a tap with H3 / 2B-3B tolerance. Ensure the tap matches the material—spiral-flute taps work well for blind holes in steel and aluminum.
