This tool is designed for forming threads in a range of materials, with the H6 / 2B-3B specification indicating its precision class and thread fit.

Frequently Asked Questions

What is the OSG Thread Forming Tap 1/2"-13 UNC used for?

This OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, low-carbon steel, and stainless steel. The 1/2"-13 UNC size and modified bottoming chamfer allow threading close to the bottom of blind holes. It is common in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG Thread Forming Tap 1/2"-13 UNC?

The OSG thread forming tap has a 1/2"-13 UNC thread size, H6 / 2B-3B tolerance, and a modified bottoming chamfer. It is made from cobalt high-speed steel for heat resistance and durability. The manufacturer part number is 1400142900. This tap forms threads by displacing material rather than cutting, producing stronger threads.

Where to buy the OSG Thread Forming Tap 1/2"-13 UNC worldwide?

3G Electric supplies the OSG Thread Forming Tap 1/2"-13 UNC (MPN 1400142900) worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver this OSG tap to any country.

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

Select an OSG thread forming tap based on thread size (e.g., 1/2"-13 UNC), material type, and hole condition. For blind holes, use a modified bottoming chamfer. Cobalt taps suit harder materials like stainless steel. Ensure the tap tolerance (H6 / 2B-3B) matches your required thread class. Always use proper lubrication and tap speed per OSG guidelines.
