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 aluminum for screw thread inserts. It is designed for through-hole applications, with spiral flutes that evacuate chips upward, preventing clogging and ensuring clean threads in softer materials like aluminum.
What are the specifications of the OSG STI tap 1/2"-20 UNF?
The OSG STI tap has a 1/2"-20 UNF thread size, H4 / 2B-3B tolerance, and 2 flutes. It is a spiral-flute design for aluminum, with manufacturer part number 1303901308. The H4 tolerance ensures proper fit for STI inserts, while 2B-3B covers standard and close-fit thread classes.
