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 in automotive, aerospace, and general manufacturing.
What are the specifications of the OSG #4-48 UNF thread forming tap?
This OSG tap is #4-48 UNF size with a H3 / 2B-3B tolerance class, plug chamfer, and made from cobalt for heat resistance. The manufacturer part number is 1400107100. It forms threads in materials up to 850 °C hardness, suitable for precision threading in thin-walled parts.

How to select the right OSG thread forming tap for my application?
Select an OSG thread forming tap based on thread size (e.g., #4-48 UNF), material type (ductile metals only), and tolerance class (H3 / 2B-3B for standard fits). Use a plug chamfer for through holes. For high-temperature alloys, choose cobalt taps. Consult OSG's technical data for optimal speeds and lubrication.
