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 threads in ductile materials like aluminum and steel. It is ideal for applications requiring high thread strength and no chip evacuation, common in automotive and aerospace manufacturing.
What are the specifications of the OSG 5/16"-18 UNC thread forming tap?
This OSG tap has a 5/16"-18 UNC thread size, H12 tolerance, plug chamfer, and TiCN coating on cobalt steel. The TiCN coating enhances wear resistance and tool life in abrasive materials. It is designed for through-hole or blind-hole threading in ductile workpieces.
Where to buy OSG thread forming taps worldwide?

As a sourcing partner, we provide genuine OSG taps like the 5/16"-18 UNC model with H12 tolerance and TiCN coating, ensuring you get the right tool for your threading application.
How to select the right OSG thread forming tap for your application?
Select an OSG thread forming tap based on thread size, tolerance class (e.g., H12), material hardness, and coating. For ductile materials like aluminum or low-carbon steel, a TiCN-coated cobalt tap offers extended tool life. Always match the tap's chamfer type (plug, bottoming) to your hole configuration.
