Frequently Asked Questions

What is the OSG Thread Forming Tap 5/16"-18 UNC used for?

This OSG thread forming tap is used to create internal threads in metal workpieces without cutting material. It displaces metal to form threads, making it ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG Thread Forming Tap 5/16"-18 UNC?

This OSG tap has a 5/16"-18 UNC thread size, H11 tolerance, modified bottoming chamfer, and TiCN coated cobalt construction. The manufacturer part number is 1400159308. It is designed for forming threads in through or blind holes with a bottoming chamfer for threading close to hole bottoms.

Where to buy the OSG Thread Forming Tap 5/16"-18 UNC worldwide?

You can source the OSG Thread Forming Tap 5/16"-18 UNC worldwide through 3G Electric. We handle full logistics, customs clearance, and delivery to global destinations. Contact us for availability and lead time on this OSG tap.

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 hole configuration. For ductile materials like aluminum, use a forming tap with TiCN coating for wear resistance. Choose a modified bottoming chamfer for blind holes. Verify thread size (e.g., 5/16"-18 UNC) and tolerance class (H11) match your requirements.
