Product Description

OSG Spiral-Flute STI Taps for Multiple Materials.

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 installing screw thread inserts. It is commonly applied in automotive, aerospace, and general manufacturing where strong, wear-resistant threads are needed in softer base materials.

What are the specifications of the OSG STI tap M4x0.7?

The OSG STI tap has a metric M4x0.7 thread size, a D3 / 4H-6H tolerance class, and a 3-flute spiral-flute design. The manufacturer part number is 34500408. It is designed for threading holes before inserting helical wire inserts.

Where to buy OSG STI taps worldwide?

OSG STI taps are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

How to select the correct OSG STI tap size?

To select the correct OSG STI tap, match the tap thread size and pitch to the insert's internal thread requirements. For M4x0.7 inserts, use an STI tap with the same designation. Ensure the tap tolerance class (e.g., D3 / 4H-6H) aligns with the desired thread fit.
