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, brass, and low-carbon steel. It is ideal for applications requiring chip-free threading, such as automotive and aerospace components.
What are the specifications of the OSG M2.5x0.45 thread forming tap?
This OSG tap has a metric size of M2.5x0.45 with a D3 / 4H tolerance class, bottoming chamfer for threading to the bottom of blind holes, and a TiN coated cobalt construction for wear resistance. The manufacturer part number is 1410100805.

How to select the right OSG thread forming tap for your application?
Select an OSG thread forming tap based on thread size, pitch, tolerance class (e.g., D3 / 4H), and chamfer type. Bottoming chamfer suits blind holes, while TiN coating improves tool life in abrasive materials. Always match the tap to the workpiece material and thread depth requirements.
