Frequently Asked Questions
What is an OSG thread forming tap used for?
An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger, burr-free threads in ductile materials like aluminum and steel. This H12 oversized tap is ideal for applications requiring precise thread fit, such as automotive and aerospace manufacturing.
What are the specifications of the OSG 3/8"-24 UNF thread forming tap?
This OSG tap has a 3/8"-24 UNF thread size, H12 tolerance, modified bottoming chamfer, and TiN coated cobalt construction. The TiN coating reduces friction and extends tool life. It is designed for forming threads in materials up to 850 °C hardness, with a modified bottoming chamfer for threading close to blind hole bottoms.

How to select the correct OSG thread forming tap size?
Select an OSG thread forming tap by matching the thread size (e.g., 3/8"-24 UNF), tolerance class (H12 for oversized threads), and chamfer type to your application. Use a TiN coated cobalt tap for harder materials. Always verify the tap drill size for forming taps, which differs from cutting taps, to ensure proper thread formation.
