Frequently Asked Questions

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

An OSG Screw Thread Insert STI Tap is used to form internal threads in pre-drilled holes for installing helical wire thread inserts. It is commonly applied in automotive, aerospace, and general manufacturing where strong, wear-resistant threads are needed in softer materials like aluminum or cast iron.

What are the specifications of the OSG STI Tap 3/8"-16 UNC?

This OSG STI Tap has a thread size of 3/8"-16 UNC with a thread class of H6 / 2B-3B. It features a modified bottoming chamfer for threading close to the bottom of blind holes. The tap is designed for thread forming, which displaces material rather than cutting it, producing stronger threads.

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

To select the correct OSG STI Tap, match the tap's thread size and pitch to the insert's specifications. For this tap, use a 3/8"-16 UNC thread insert. Ensure the tap's thread class (H6 / 2B-3B) aligns with your required tolerance. Always verify the chamfer type—modified bottoming for blind holes or plug for through holes.
