Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and steel without cutting. It displaces material to form threads, producing stronger, burr-free threads ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG thread forming tap 1400139905?

The OSG thread forming tap has a thread size of 7/16"-14 UNC, a tolerance class of H12 / 2B, a modified bottoming chamfer, and a TiN coated cobalt construction. It is designed for oversized thread forming in materials requiring precise internal threads.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location, ensuring you receive genuine OSG taps for your manufacturing needs.

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

To select the right OSG thread forming tap, match the thread size and pitch (e.g., 7/16"-14 UNC) to your hole requirements. Consider material hardness, coating (TiN for wear resistance), and chamfer type—modified bottoming for blind holes. Consult OSG's technical data for optimal performance.
