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. It is commonly used in automotive, aerospace, and general manufacturing for applications requiring high thread strength and no chip evacuation.

What are the specifications of the OSG 3/8"-16 UNC thread forming tap?

This OSG thread forming tap has a 3/8"-16 UNC thread size, H5 / 2B-3B tolerance, and a modified bottoming chamfer. It is made from cobalt for heat resistance and durability. The manufacturer part number is 1400135100.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source genuine OSG taps and deliver them to your facility, ensuring compliance with local import requirements.

How to select the correct OSG thread forming tap for your application?

Select an OSG thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum or steel, use a forming tap with the correct chamfer (e.g., modified bottoming for blind holes). Always match the tap's H limit to the required thread class (e.g., H5 for 2B-3B).
