Frequently Asked Questions

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

An OSG Screw Thread Insert STI Tap is used to cut internal threads in a pre-drilled hole before installing a helical wire thread insert. It is commonly applied in automotive, aerospace, and general manufacturing to repair or strengthen threads in softer materials like aluminum or cast iron.

What are the specifications of the OSG STI Tap M22x2.5?

This OSG STI Tap has a metric thread size of M22x2.5, a D5 / 4H-6H tolerance class, 4 flutes, and is made from high-speed steel. The spiral-flute design aids chip evacuation in through-hole applications. The manufacturer part number is 10901400.

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 thread insert you plan to install. For example, an M22x2.5 tap corresponds to a thread insert of the same nominal size. Also verify the tolerance class (e.g., D5 / 4H-6H) matches your application requirements.
