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.
