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 multiple materials for screw thread inserts. It creates threads that accept helical coil inserts, commonly in aerospace, automotive, and general manufacturing. The spiral flute design helps evacuate chips upward, making it suitable for through-hole and blind-hole applications.

What are the specifications of the OSG Screw Thread Insert STI Tap #6-40 UNF?

The OSG Screw Thread Insert STI Tap has a #6-40 UNF thread size, H2 / 2B-3B tolerance, and 3 flutes. It is a spiral-flute design for multiple materials. The manufacturer part number is 31500308. This tap is designed to produce threads that accept STI inserts, ensuring proper fit and strength.

Where to buy OSG STI taps in worldwide?

You can source OSG STI taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location.

How to select the correct OSG STI tap for a thread insert application?

Select an OSG STI tap based on the thread size and pitch required for the insert, such as #6-40 UNF. Ensure the tap tolerance (e.g., H2 / 2B-3B) matches the desired thread class. Use a spiral-flute design for chip evacuation in blind holes. Always refer to the insert manufacturer's recommendations for tap specifications.
