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. It is ideal for high-speed production in automotive, aerospace, and general manufacturing applications.
What are the specifications of the OSG #5-40 UNC thread forming tap?
This OSG tap is #5-40 UNC with a plug chamfer, H2 / 2B-3B tolerance, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in abrasive materials. It is designed for through-hole or blind-hole threading in ductile workpieces.

How to select the right OSG thread forming tap for aluminum?
For aluminum, choose a TiCN coated tap like this OSG #5-40 UNC to reduce galling and improve chip evacuation. Ensure the tap's H2 / 2B-3B tolerance matches your thread class requirement. Use proper lubrication and a rigid tapping cycle to prevent breakage in soft materials.
